Happy April Fools day! Fortunately for me, my siblings haven't even remembered that it's today, and I didn't bother reminding them. Maybe tomorrow I'll tell them that it's April fools day… Ok, so I'm just mean.

Thanks to my reviewers (ooh, I love saying that): Marian Locksley, milady dragon, the darkness revealed, specialfrancine, Alibrandi, gernumblies, L.A.H.H. and Ravenja70. Really really thanks – I love reviews! Reviews = more story + happy Beth.

Chapter 1

Wednesday 1st April

"Oh god!" Gwen jumped as her mobile started ringing, jerking her out of her breakfast reverie. She made an apologetic face at Rhys as she picked it up, followed by an annoyed one as she saw who the call was from.

"Work, eh?" Rhys asked as he put his own plate of toast down on the table, but Gwen didn't answer.

"Hi Jack."

"Hi Gwen. Look, things are a little busy down here right now, so I need you to check something out for me."

"Err, yeah, ok."

***

Back in the Hub, Owen sniggered slightly as Jack played Gwen's side of the conversation over the speakers.

***

"Ianto's been getting reports of some sightings over at some disused warehouses over in Splott. Apparently some dog walker saw something – no description, by the way - and got scared. Doesn't sound like anything dangerous, but I'd take your gun just in case."

"Yeah, fine. I can be onto it in…" Gwen glanced at her watch. "About half an hour?"

"That's great. I'll send you the coordinates now. Thanks Gwen."

Gwen put the phone down as Jack hung up. Her husband looked at her curiously as she began shovelling down the remains of her breakfast. "So…?"

"Another bloody reconnaissance mission." Gwen dropped her spoon and grabbed her bag and car keys. "But it sounds like they need me back at the Hub straight after, so I'd better be off."

"What time will you be back?"

"Oh, I don't know. Before breakfast tomorrow?"

"I'll cook dinner tonight then, shall I?"

"That'd be great, yeah." Gwen dropped a kiss on Rhys' head as she hurried past. "Got to go."

"Bye, then!" he called after her and was rewarded by the sound of the flat door slamming shut.

***

In reality, the only thing Jack, Owen and Ianto were busy with was cracking up laughing.

"She fell straight for it!" Owen gasped.

"Hook, line and sinker." Ianto agreed. "Oh, hi Tosh."

"Hello." Tosh looked at them carefully. "What are you up to?"

Jack gave her a secretive smile, and was about to explain, when Owen opened his mouth first, looking very guilty.

"Err… Tosh?"

"What, Owen?"

"Err, I sort of broke your computer…"

"Very funny, Owen, but you're not getting me that easily." Tosh walked past the little group towards her desk.

"Actually…" Ianto began, "he did break you computer. You see, he was trying to pour a bucket of water over me, but I dodged and…"

Ianto's explanation was interrupted by a scream of fury which sounded more like it came from Myfanwy than from Tosh. "Owen!"

Gwen drew the car to a stop and looked up at the building looming above her. She checked the map – this was definitely the place. Maybe Jack hadn't realised quite how large it was. It looked pretty ancient too; from the outside she could see that most of the windows had the glass smashed in, and the whole pace had a rundown look. She was willing to bet that no one had been inside in years. And all that, of course, made it the perfect lair for all kinds of alien riffraff.

She checked to make sure that she had her gun, torch and comms and walked up to the door. It had a warning sign on it, saying that the building was structurally unsound. Gwen ignored it – it was probably just there to deter trespassers. If the building really was unsafe Jack would have told her. She was about to give the door a good hard kick when she noticed that it was slightly ajar anyway. Taking a deep breath she switched on her comms.

"Jack, I'm going in."

***

"Ok. Keep us informed if you find anything. And be careful." Jack signed out before Gwen had time to pick up on Owens sniggers over the comms.

Tosh's eyes narrowed suspiciously as she looked up from the rewiring she was doing. "That's what you were laughing about, wasn't it? You're playing games with Gwen."

"Excellent detective work, Miss Sato!"

"And PC Cooper doesn't suspect one bit." Owen gloated. "What's up?" he asked mockingly, seeing the expression on Tosh's face harden. "Is it too cruel, or something?"

Tosh shrugged. She didn't really care what they were all up to right now. She had better things to do. Fixing her computer, for a start.

***

Gwen shone her torch up the flight of dusty stairs and then along the shadowy corridor. There were five floors - she'd counted outside. Maybe cellars too. And she had to check them all. Sighing, she started walking down the long corridor, resolving to search the first floor first then work up.

***

"Coffee, sir?"

"No thanks, Ianto. I'm sure it'll have sun cream in it, or some other humorous flavouring."

"Sun cream, sir? Wherever did you get that idea from?"

***

Doing a few mental calculations in her head Gwen worked out that this room was at least the twentieth she had searched. And with at least another twenty more to go on this floor alone and another five floors… that made nearly two hundred rooms. She really, really hoped that there weren't cellars as well.

"How long before she works it out, do you think?" Owen asked as he swivelled round in his chair.

Jack shrugged. "She must have been there nearly an hour by now… How big is it, Ianto?"

"Quite big, sir. But I'd be expecting an angry call from her quite soon."

***

Gwen brushed her hair out of her eyes with dusty fingers. The atmosphere in the building was really beginning to freak her out. It was getting to the stage where she'd almost be glad to find something, just to bring the waiting to an end. And the feeling in the pit of her stomach – the one that was telling her that something was very, very wrong – was growing. One more room, she promised herself. One more room and then we'll call the others to check that… well, to check that this isn't just a false alarm.

She pushed open the door, and was instantly hit by a smell she knew only too well. Dead meat, of some sort or another. It was probably just a dead rat, but her hand tightened on her torch anyway. With her other hand she drew her gun out of her pocket, and cautiously began to approach the pile of cobwebbed packing crates on the other side of the room.

She never reached them.

Somewhere in between me starting this story and actually getting this far it somehow turned into a horror story instead of a comedy. I don't really mind, since I was intending to try writing horror at some point anyway. So no apologies for the cliff-hanger.

Oh, and someone please tell me whether or not the switching viewpoints thing works or not. I'm a bit uncertain about it myself. And about the cliff-hanger. And about most of the rest of the story, really.
