The TARDIS landed smoothly and the pair strolled out. Rose seemed reasonably normal despite their last adventure; Donna couldn't help but be glad Sarah Jane was there to help. After a take out dinner and spending the night there, Rose was ready to leave hugging both Sarah Jane and Luke, giving promises to visit again. Donna looked round to see they landed in the garden of some posh house.

"Where are we?" Donna asked.

"Haven't got a clue" Rose said looking up at the clear blue sky.

"I think we might be in the 1920s" Donna said smirking.

"Oh yeah? How did you come up with that one?" Rose asked walking forwards still looking up at the sky with a soft smile it was like she never saw a sunny day...actually she probably hadn't for yonks.

"Because you're about to be run over by a vintage car" Donna said.

"wha-" there was a honk and Rose leaped back in time to avoid being hit.

"Haven't you seen a sunny day before?" Donna asked laughing. "You're head was literally stuck in the clouds"

"Nah I was just enjoying the sun while it lasted, I think there's a party going on. Want to have some fun?"

"But we haven't been invited" Donna said.

Rose pulled out the psychic paper. "Now we have" she said with a sly smile. "Race you to the wardrobe room"

DWDWDWDWDWDWDWDWDWDW

The two strolled along arm in arm, Donna in a brown flapper dress and Rose in a dark green one both grinning insanely. An old woman of roughly sixty was ordering the waiters around, one of them bowed to the young women.

"Good afternoon" he said. "May I get you a drink Ma'ams?"

"Sidecar please" Donna said putting on her best posh voice.

"And I'll have the same" Rose said smiling politely.

"May I announce Lady Clemency Eddison" the older butler said as a middle aged blonde woman strolled out in navy blue.

"Lady Eddison" Rose cried out holding her hand out which Lady Eddison took and shook firmly.

"Forgive me" she said politely "but who might you be? What are you doing here?"

"I'm Dame Rose Tyler of the Powell Estate" Rose said calmly. "And this is Miss Donna Noble of the Chiswick Nobles"

"Good afternoon milady" Donna said putting on a 1920 accent. "Topping day, spiffing. Top hole"

"No, no, no, don't do that" Rose murmured feeling rather embarrassed for her and Donna. She then flipped out the psychic paper. "We were thrilled to receive an invitation milady; we met at the ambassador reception"

"Dame Rose how could I forget you?" Lady Eddison said, leading them to the table with a true hostess smile. "Though one has to be sure with the Unicorn on the lose"

"A unicorn?" Rose asked gleefully. "Brilliant, where?"

"No The Unicorn, the jewel thief and no one knows who he is" Lady Eddison explained. "Just struck again and Lady Babington's pearls right from under her nose."

"Funny place to wear pearls" Donna muttered causing Rose to bite her lip to stop laughter from coming out. The waiter handed Rose and Donna their drinks and they both took a quick sip in unison.

"May I present the Colonel Hugh Currishly and the Honourable Roger Currishly" the butler said as a young man wheeled in an old man on a wheelchair.

"My husband" Lady Eddison giggled "and my son"

"Forgive me for not rising" the Colonel said "nerves haven't been the same since that flu epidemic in '18"

"My word" Roger said staring at Donna "you are a super lady"

"Oh" Donna said smiling coyly as she shook his hand. "Oh, I like the cut of you're jib…chin-chin."

"I'm Dame Rose how do you do?" Rose said politely shaking Roger's hand.

"Very well thank you" Roger said.

A young waiter came up to him. "your usual sir" he said.

"Ah thank you Davenport" Roger said taking the glass. "just how I like it"

"How come she's an Eddison but her husband is a Currishly?" Donna asked Rose quietly.

"The Eddison title is hers, one day that Roger guy will be a Lord" Rose murmured.

"Miss Robina Redmond."

Lady Eddison waved towards Robina and then turned back to Rose and Donna. "She's the absolute hit of the social season. A must, Miss Redmond."

"Reverend Arnold Golightly."

Lady Eddison and the Reverend began a conversation about a burglary in the church where apparently the Reverend had stopped them. Roger agreed whole-heartedly that the boys deserved 'a good thrashing' and the young waiter Davenport also agreed flirtatiously.

"Typical" Donna hissed. "all the good guys are on the other bus"

"Or idiots" Rose murmured thinking about the only good guys she ever had...Mickey, the Doctor, James, the human version of the Doctor...all four were proud idiots in their own way.

"Now my lady," Reverend Golightly said rather loudly obviously wanting to change the subject. "What about this special guest you promised us?"

Lady Eddison smiled at someone behind them all "Here she is, a lady who needs no introduction."

The small group turned round and all clapped as a tall blonde walked towards them.

"Oh, no" The blonde woman said looking modest "please don't. Thank you, Lady Eddison, honestly, there's no need." She walked up to Donna and Rose who wore smiles, pretending they knew who this woman was. "Agatha Christie." The woman held her hand out to Donna.

"What about her?" Donna asked.

"That's me" Agatha said smiling awkwardly.

"NO!" Donna said looking stunned.

"Agatha Christie!" Rose said shaking the woman's hand. "Oh I loved your stuff! Used to read it with my grandmother when I was a little girl! I'm Rose and this is Donna, oh what brilliant stuff you have written."

"Such an unusual child" Agatha said "though you won't be for much longer"

"What?" Rose asked nervously.

"You must be nearing the end of your teenage years, dear" Agatha said.

"Oh yes, yes of course" Rose blustered, for a moment she had a flashback of the beast, why she did not know but recently she had felt on edge.

Lady Eddison pulled Agatha Christie away and everyone began to discuss her husband and her work as Rose spied a newspaper and picked it up to check the date. Rose frowned, the Doctor being a big literate fan had told her everything she knew about Agatha Christie including her mysterious disappearance, she gestured to Donna who walked up to her.

"Today's date" she murmured.

"What about it?" Donna asked.

"It's the day Agatha Christie disappears" Rose said. "She just discovered that her husband was having an affair."

"You wouldn't think so, the way she's smiling away" Donna commented.

"Well she's British and has loads of money" Rose said "they ignore things, carry on. Except for this one time...she just vanished. Her car will be found tomorrow morning by the side of a lake and days later Agatha Christie turns up at a hotel in Harrogate. She lost her memory; she never spoke about her disappearance till the day she died but whatever it was..."

"It's about to happen" Donna realised.

"Right here and right now"

There was suddenly a scream and someone shouting murder on the top of their voice.

DWDWDWDWDWDWDWDWDWDWDW

The three women and the butler ran in to find a body laying on the rug. "oh my goodness!" the butler choked out as Rose and Agatha fell onto their knees to examine the body.

"Blow to the head" Rose decided. "Blunt object" she fingered his watch which was broken. "Watch broke as he fell, he died quarter past four"

"Bit of pipe, call me Hercule Poirot, but I reckon that's blunt enough." Donna muttered.

Rose raised an eyebrow at her noticing from the corner of her eye that Agatha knelt down and picked something up from the fireplace. She ignored it for now, knowing that whatever she found would be important later.

"Nothing worth killing for in that lot, dry as dust." Rose said.

"The body in the library" Donna said to Rose. "I mean Professor Peach in the library with a lead pipe" Rose sniggered at the reference to Cluedo. Suddenly the other guests came bursting in and soon became hysterical.

"We should call the police" Agatha said.

"No need" Rose said pulling out her psychic paper. "Detective Rose Tyler and detective Donna Noble are on the job"

"Why I say" Lady Eddison muttered.

"Now I need you all to go out so I can examine the crime scene in peace" Rose ordered, Agatha herded everyone out and Rose knelt on the floor examining the fireplace and the floor surrounding it carefully.

"And why aren't we calling the real police?" Donna asked.

"Because I don't wan PC bloody Plod interfering" Rose snapped, she then gasped and held something up. "look what I found, morphine residue"

"Morphine?" Donna said incredulously. "Doesn't sound very 1926"

"That's because it's an alien genetic code" Rose murmured.

"The murderer is an alien" Donna said sounding even more incredulous.

"Yep one of the guests is an alien in human form" Rose said absently.

"Yeah but think of it, there's a murder, a mystery and Agatha Christie" Donna whispered rapidly.

"So? Happens to me all the time" Rose said holding the residue out for Donna to sniff who flinched away with a disgusted look.

"I know but Agatha Christie didn't go around surrounded by murders, not really. I mean that's like meeting Charles Dickens and he's surrounded by ghosts, at Christmas"

"Remind me to tell you that story" Rose said. "it was my first ever trip to the past"

"Oh come off of it!" Donna spluttered. "Next you're telling me we're going to drive across the country to meet Enid Blyton who's having tea with Noddy!" she paused. "could we? Noddy isn't real, tell me he isn't real!"

Rose stared at Donna in amusement. "I promise you that I never in my life have met Noddy and I am sure I'll never will but if I do, I'll tell you yeah?" she then strolled out, Donna following.

"Next thing you'll tell me that it's Murder on the Orient Express and they all did it" she said.

"Murder on the Orient Express?" Agatha asked coming out from a door.

"Yeah one of your bests" Donna said.

"But not yet" Rose hissed.

"Marvellous idea though" Agatha said slyly.

"Yeah tell you what, copyright Donna Noble" Donna said.

"Pardon?"

"Anyway" Rose butted in. "Agatha I'm going to question the suspects while Donna will search the rooms" she whispered to Donna "look for more residue, you'll need this" she pulled out a giant magnifying glass that the TARDIS has put in there.

"Are you for real?" Donna asked raising an eyebrow.

DWDWDWDWDWDWDWDWDWDWDW

The Reverend was unpacking his luggage in his room, Roger was taking a stroll in the woods 'alone' (though Rose assumed that he was with Davenport the way Roger kept saying his was alone), Robina Redmond was in the bathroom preparing for the party, the Colonel was in his study (and got stuck in the flashback, Rose assumed those military memoirs were actually pornography) and Lady Eddison was in the blue room drinking tea.

"No alibis for any of them" Agatha said sighing as both she and Rose paced the room. "we got to look for the motive...look for the grey cells."

"Poirot" Rose said sitting in the chair sipping her tea. "you know I went to Belgium once...very muddy, then again I was in the woods"

"Rose for such an experienced detective you're missing something. A very big clue" Agatha said.

"What the little bit of paper you nicked from the fireplace?" Rose asked raising an eyebrow.

"But you had your back to me!"

"Yeah but I saw your reflection" Rose said shrugging.

Agatha smirked. "You crafty girl" she pulled out the paper. "This was all that was left" Rose put down her tea and ran over to Agatha's side.

"What's that first letter? M or N?"

"An M for maiden"

"But what does that mean?"

"No idea...our nemesis remains at large unless Miss Noble has found something"

"ROSE!"

"Something tells me she has" Rose said running out of the room, Agatha hot on her heels.

"ROSE!"

They ran up the stairs and down the corridor as they heard Donna let out a shrill scream. They found her by a door panting and looking terrified.

"There is a giant wasp" she said.

"What do you mean a giant wasp?" Rose asked.

"I mean there's a wasp that's GIANT!"

"It's only a silly little insect!" Agatha cried out looking amused.

"When I say giant, I don't mean big I mean flipping enormous!" Donna said looking annoyed. "Look at its sting" she said pointing at the giant stinger that stuck out through the door.

Rose ran in the room. "It's gone, buzzed off, vamoosed" she said peering out the broken window.

"But that's fascinating" Agatha said kneeling down to touch the giant stinger. Rose ran back.

"No touching, let me" she got out a test tube and tweezers and pulled out golden goo slowly before putting it in the tube. "Lots of morphemes nectar species out there but none in the galaxy"

"I understood enough of that to know you're completely potty!" Agatha snapped.

"Lost its stinger though" Donna commented. "That makes it defenceless"

"Creature this size? It can grow a new one"

"Can we please return to sanity?" Agatha asked. "There's no such thing as giant wasps!"

"So why is one here then?" Rose asked getting up and leaving the room.

DWDWDWDWDWDWDWDWDWDWDWDW

The housekeeper was murdered, a stone gargoyle landed on top of her, her last words were 'the poor little child', they had turned in time to see the wasp flying away. They chased the wasp to a hallway and when Rose shouted for it to show itself everyone came out of the room. Rose considered it as cheating. No one knew what the dying words meant and everyone believed Agatha could help them, Agatha admitted she could do nothing to help and the only one that could was Rose who everyone immediately turned to look at. Great just great Rose thought sarcastically.

Agatha and Donna went out to have a chat and came back presenting a black leather case to Rose. Who started going through it.

"Oh someone came well packed haven't they?" Rose said thoughtfully. "This would be something a thief would use"

"The Unicorn, he's here!" Agatha exclaimed.

"The Unicorn...or someone else" Rose murmured as the door opened and the butler passed them their drinks.

"How about the science stuff?" Donna asked. "What did you find?"

Rose pulled out the test tube. "Hmm...yes. it's a Vespaform. Vespaforms are from the X Galaxy"

"Again you're talking like Edward Lear"Agatha said.

"But for some reason this Vespa is acting like one of your characters" Rose said taking a sip of her drink.

"Come on Agatha what would Miss Marple will do? She would have heard something vital now because everyone thinks she's a harmless old lady" Donna said.

"Clever idea! Miss Marple, who writes those?" Agatha asked.

"Erm...copyright Donna Noble, add it to the list" Donna said sheepishly.

"Donna..." Rose said.

"Ok we can split the copyright" Donna joked.

"No...something is inhibiting my enzymes" Rose groaned before letting out a shriek and sitting up quickly. "I've been poisoned!"

Donna and Agatha ran to Rose's side. "What do we do? What do we do?" Donna asked as Rose started to have what looked like a bit of a seizure.

Agatha examined the drink "it's Cyanide, sparkling Cyanide" she shouted. Rose got up and began to run. The other two women followed.

Rose staggered into the kitchen. "Ginger Beer!" she shouted to Davenport.

"I beg your pardon?"

"I need Ginger Beer!" Rose said throwing the contents of the shelve off and picking up the Ginger Beer bottle.

"That girl has gone mad!" the cook shouted.

"Rose that poison is completely toxic, there's no cure!" Agatha cried out looking distressed as Rose poured the Ginger beer over her head. Rose spat some Ginger beer out.

"Not for me! I can reverse it, I need protein, give me some protein!" she said panting as Donna ran off. Donna shoved a jar into Rose's hand and Rose poured the contains in her mouth, taking deep breaths. She then began to motion for something.

"I can't understand you!" Donna shouted. "How many words?" Rose held a finger up. "One, ok shake...shake...milkshake? no not milk, not milk...cocktail shake, what you want a Harvey Wallbanger?"

"Harvey Wallbanger?" Rose spat out looking incredulous.

"Well I don't know!"

"How is Harvey Wallbanger one word?"

"What do you need Rose?" Agatha shouted.

"Salt! I was miming salt, Jesus Christ!"

"How about this?" Donna asked holding a package up.

"What is it?" Rose asked.

"Salt!"

"Too salty"

"Oh it's too salty" Donna grumbled sarcastically.

"What about these?" Agatha asked, Rose nodded and snatched the jar and swallowed the contains.

"What are they?" Donna asked.

"Anchovies" Agatha said.

"what else?" Donna asked. "What else do you need?" Rose began to mime again. "it's a song? A Mammy? I don't know, Camptown Races?"

"Camptown Races?" Rose cried out looking disbelieving.

"Well how about Towering Inferno?" Donna asked.

"It's a shock, I need a shock!" Rose shouted. "Blimey woman how many charade games have you won?" Donna slapped her hard. "that's not a shock! That's just you! You almost slapped me several times on the day we me-"

Donna shut Rose up with a snog. Rose pulled back stumbling as grey and black gas poured out of her mouth.

"Right" she gasped wiping her mouth. "Detox, must do that more often, the detox not the snogging. I had enough companions trying that. Martha and Jack couldn't keep their hands off of me"

Donna raised an eyebrow in disbelieve.

"What are you?" Agatha asked looking shocked.

DWDWDWDWDWDWDWDWDWDWDWDW

At dinner, everyone was seated around the table, dressed in their finest clothes while slowly eating the soup placed in front of them.

"A terrible day, for all of us…with the professor being struck down, the housekeeper cruelly taken away from us and yet we still dine like nothing happened." Rose said glaring at everyone.

"We are British Rose, what else must we do?" Lady Eddison asked.

"Then someone tried to poison me, any one of you had the chance to put cyanide in my drink…but it rather gave me an idea." Rose continued as if Lady Eddison never spoke.

"What would that be?" The Reverend asked.

"Well…poison" Rose said shrugging. "Drink up" She smiled sweetly. Everyone stopped eating and looked at her in shock, Donna spat out the soup she was eating. "I laced the soup with pepper" Rose continued and everyone sighed in relief.

"Ah, I though it was jolly spicy." The Colonel said.

"well you see pepper is traditionally used as insecticide. So anyone got the shivers?"

Suddenly the sound of thunder crashed through the room and the lights went out. One window's had opened, hustling the wind in, burning out the candles. A faint buzzing sound began to erupt in the room.

"What the deuce it that?"

"Shh…listen" Rose hissed, listening intently to the sound.

As the buzzing got louder, Lady Eddison rose from her seat whispering, "It can't be." On the opposite side of her Agatha Christie also rose from her seat.

"Show yourself, demon!" she shouted into the blackness of the room.

"Nobody move…stay where you are!" Rose yelled. The wasp came out of the darkness, Robina and Lady Eddison screamed, while Rose, Donna and Agatha ran out of the room with the butler beside them.

"Well at least we know that the butler didn't do it" Donna said.

"Then who did?" Rose asked pulling the sword from the wall and running back in. The lights flickered on and Roger was found dead and the crystal necklace of Lady Eddison's was missing.

DWDWDWDWDWDWDWDWDWDWDW

"That poor footman, Roger's dead and he can't even mourn him…1920's…it's more like the dark ages." Donna grumbled as she took a seat beside Agatha.

"Did you enquire about the necklace?" Agatha asked.

"Lady Eddison brought it back from India, it's worth thousands."

"It can sting, it can fly, and it could wipe us all out in seconds…why is it playing this game." Rose asked darkly.

"Every murder is essentially the same; they are committed because somebody wants something." Agatha said thoughtfully.

"Yeah but what would a Vespaform want?" Rose asked.

"Rose stop it! Whatever it is it's human as you and I" Agatha snapped.

"You're right" Rose whispered. "I've been so caught up in giant wasps that I forgot that you're the expert!"

"Rose stop it! I'm just a writer and not a very good one!"

"No, no, no you don't just write detective stories, you're the best of the best. And why is that? Why are you so good Agatha? Because you understand, you lived; you had your heart broken. You know about people, their passions, their hopes and their anger. You know all of these things; you know what can make the most ordinary person into a killer. Just think Agatha, if anyone can solve this it's you!"

DWDWDWDWDWDWDWDWDWDWDWDW

Everyone was crowded round the drawing room, on the sofas as Rose stood in the centre before the fireplace.

"I called you here on this endless night because we have a murderer here among us" Rose said quietly. "And when it comes to detection there is no one more finer...Ladies and Gentlemen I give you Agatha Christie" Rose took a seat by Donna as Agatha stepped forwards.

"This is a crooked house, a house of secrets, to understand the solution; we must examine them all…starting with you, Miss Redmond." Agatha said shooting a look at the young brunette woman, everyone turned to look at her.

But I'm innocent, surely." Miss Redmond said nervously playing with her necklace.

"But you never met these people" Agatha said calmly. "And these people never met you; I think the real Robina Redmond is still in London, you're impersonating her!"

"How silly" Miss Redmond said smiling. "What prove do you have?"

"Oh I know this" Donna butted in. "If she was really posh she would have said loo"

You said you'd been to the toilet. Earlier today, I found this on the lawn," Agatha said ignoring Donna and turning to pick up the black leather box. "Right beneath your bathroom window, you must have heard Miss Noble was searching the rooms and panicked. You ran upstairs and disposed of the evidence."

Miss Redmond placed her wine back down. "I never seen that thing before in my life" she said calmly.

"What's inside it?" Lady Eddison asked.

"The tools of your trade, Miss Redmond, or should I say The Unicorn," everyone gasped. "you came to this house with one intention - to steal the Firestone."

Miss Redmond got up. "Oh, all right fine, it's a fair cop. Yes, I'm the bleeding Unicorn. Ever so nice to meet, I don't think, I took my chance in the dark and nabbed it" she said losing her posh accent and gaining a rougher one. She pulled out the necklace from the strap of her dress and swung it around. "Go on then, you knobs, arrest me, sling me in jail."

She threw the necklace at Rose who caught it swiftly. "So is she the murderer?" Donna asked her mouth full of nuts.

"Don't be so thick, I might be a thief but I ain't a killer." Miss Redmond said leaning on the Colonel's chair.

"Quite and to find the darker motives we have to continue our investigation. And now we come to you...Colonel" Agatha said looking at the Colonel.

"Damnit woman!" the Colonel spat out. "you rumbled me!" he stood up.

"Hugh, you can walk" Lady Eddison gasped. "But why?"

"My darling, how else could I be certain to keep you by my side" the Colonel asked taking his wife's hand.

"I don't understand" Lady Eddison said shaking her head.

"You're still a beautiful woman Clemency" the Colonel said sighing. "Sooner or later a young chap would have turned your head, I couldn't bear that, staying in that chair was the only way I could be certain of keeping you. Confounded Mrs Christie how did you find the truth?"

"Erm actually I had no idea, I was going to say that you were completely innocent" Agatha said blinking.

"Oh"

"Sorry"

"Shall I sit back down then?"

"I think you better had"

Rose sniggered as Donna asked once again with her mouth full. "So he's not the murderer?"

"Indeed he's not" Agatha agreed. "To find the truth, let's return to this," Rose handed her the Firestone. "This far more than the Unicorn's object of desire, the Firestone has quite a history…Lady Eddison."

"I've done nothing." Lady Eddison whispered.

"You brought it back from India, did you not? Before you met the Colonel, you came home with Malaria, and confined yourself to the house for six moths, in a room that has been locked ever since, which I rather think means-"

"Stop! Please!" Lady Eddison interjected.

"I'm so sorry, but you had fallen pregnant in India, unmarried and ashamed, you hurried back to England with your confidante, young maid…later to be the housekeeper, Miss Chandrakala."

"Clemency is this true?" the Colonel asked.

"My poor baby." She began to sob, "I had to give him away, oh, the shame of it."

"But you've never said a word?"

"I had no choice, imagine the scandal, the family name, I'm British…I carry on."

"It was no ordinary pregnancy." Rose muttered.

"How can you know that?" Lady Eddison glared at her.

"Sorry, Agatha, my territory. When you heard that buzzing sound in the dining room, you said 'it can't be' why did you say that?" Rose asked Lady Eddison.

"You'd never believe it."

"Rose has opened my eyes to believe anything" Agatha said reassuringly.

Lady Eddison told them a tale, a tale of a man called Christopher who she fell in love with, who was not human, who showed her his true shape but it didn't matter to her because she loved him. But he had died in the flood but before he died he had given her the Firestone.

"Just like a man, he flashes his family jewels and you end up with a bun in the oven." Miss Redmond snorted.

"A 'poor little child', forty years ago, Miss Chandrakala took that newborn baby to an orphanage but Professor Peach worked it out, he found the birth certificate." Agatha said.

"Oh that's maiden, maiden name" Donna said.

"Precisely."

"So she killed him?" Donna asked.

"I did not!" Lady Eddison objected.

"Lady Eddison is innocent" Agatha said. "Because this point...Rose"

"Thank you!" Rose said getting up. "from all the lies and truths we have to consider...it was you Donna Noble" she said pointing at the redhead.

"What? Who did I kill?" Donna asked swallowing.

"No sweetie you had it right all along" Rose said trying her hardest not to laugh. "That this was being acted out like a murder mystery which means...it was you Agatha Christie!"

"I beg your pardon" Agatha snapped.

"So she killed them!"

"No Donna, she wrote, wrote those clever books and who is her greatest fan? Lady Eddison"

"Leave me alone" Lady Eddison whimpered.

"So she did kill them!"

"No Donna" Rose said sighing in frustration. "Just think, last Thursday night, what were you doing?"

"erm, I was in the library reading my favourite Agatha Christie"

"Now, Reverend, think, what happened Thursday?"

"I'm sorry?"

"You said on the lawn this afternoon, last Thursday, boys broke into the church."

"That's correct…they did." He shifted nervously "but I apprehended them."

"Really? A man of God against to strong lads, a man in his forties? Or should I say, forty years exactly." Rose smiled slightly. "Lady Eddison, you're child, how old would he be now?" Lady Eddison just looked at the Reverend, shocked. Rose walked closer to him. "You realized you're inheritance, after all these years, you knew who you were…what's that like?"

"Oh my god" Lady Eddison cried out.

"Last Thursday, you got angry very angry and you broke the genetic lock" Rose said before the reverend could deny it. "this" she picked up the Firestone. "Is a Vespaform telepathic recorder, it's part of you, part of your brain, part of your very essence. It beamed everything you know about yourself as a Vespa into your mind and at the same time the works of Agatha Christie"

"So he killed them?"

"Yeah," Rose said. "You finally got that one right"

"Well," the Reverend stood up, "This has certainly been a most entertaining evening, really, you can't believe any of this, surely, Lady Eddizzz…"

"Sorry didn't catch that Rev?" Rose said sarcastically.

"Lady Eddizzzon" the Reverend buzzed.

DWDWDWDWDWDWDWDWDW

The Reverend turned into his true form and Agatha got him to follow her by snatching up the Firestone and running out of the house, she drove to the lake, Rose and Donna following and threw the Firestone in, the Vespaform followed, drowning. The Firestone connected to Agatha wiped out her memories of the day. Rose dropped Agatha off at the hotel finally solving the mystery of Agatha Christie.

"So all that time" Donna whispered. "It was us that took her"

"Yep" Rose said. "But some of the stuff leaked through. Say...Miss Marple"

"Ahhhhh" Donna said "I should have written up a contract and gotten my ten percent"

"Oh well you win some and you lose some" Rose said shrugging. "Now I believe I promised you a tale of Charles Dickens, ghosts and Christmas"

"Hold on a moment, I'll put the kettle on" Donna said walking back into the TARDIS, Rose following.
