A/N: This is a first attempt at a DR Who fanfiction but I've been watching it for as long as i can remeber so I decided to take the plunge and try it out, please R&R if you please.

Chapter 1- The first meeting.

Harry ducked into a supply closet when he heard the whooshing sounds, he couldn't be sure if it was some kind of security measure Van Statten had put in place which irked him. He'd scoped out the place extremely well, men like Van Statten were easy targets, and discovered the usual haunts. A Leroy 300 vaulting system, he could crack that in under ten minutes and after that it was pure key codes most of which were so worn down all it would take was a few minutes of guesswork and then he'd be in. "-hat is it, What's wrong" A female voice said, London if he cared to guess.

"Don't know some kind of signal throwing the TARDIS off course" A man's voice this time, from the north. As much as Harry felt like cheering that the Brits were invading the US, he wasn't in so much of a hurry to be arrested again. His 'acquired' wristband beeped, so Van Statten was more than a rich arse hole collecting pricey art work? He dabbled with Alien tech too; Harry smiled his pay check seemingly rising. He loved a challenge. When the pair of voices drifted away he opened the door and slipped back out.

He shucked his bag and pulled out his glass cutting tools, clipping it to the glass display case and letting it do its work while he looked at the merchandise. It was some hunk of fossilised life form, not his normal penchant but he'd learned long ago that where there were illegal goods there was a black market for all of it.

By the time he'd worked his way through the cases his bag was beginning to get full. He walked back to the supply closet and dumped his first duffel bag in the vent grabbing the empty one on his way out. When he walked out he was smiling until he came face to face with a group of armed guards "Ah….Any chance you'd believe me if I'd said I'd got lost on the tour?" The one who was apparently in charge shook his head sternly his gun not wavering, Harry hummed "Thought so" he followed them when they motioned for him to do so.


Harry was pushed into a room by the nice man with a gun and walked in to find a man wearing a leather jacket with some…odd ears, a blonde girl sitting near them, a weedy looking man (Adam, in charge of Van Statten's new acquisitions) watching in awe as the big eared man gently stroked something in his hands. "Who the hell is this?" Van Statten asked a frizzy haired woman behind him. "I-I don't know sir, he was found on the same floor as those two"

The big eared man looked at him, opening his hands revealing what had been making the noise, "Huh, A circillian music pipe…that's rare" he commented- he'd stolen one of those years ago his contact had told him what it was and what it was worth, sinking into a seat and putting his feet on Van Statten's desk, "Good eye, Who are you" The big eared man asked

"Someone passing through, who are you"

"I'm the doctor, this is Rose" He said pointing at the blonde girl who smiled and gave a little wave

"Now I know who you are" Van Statten said with a smug little smile, he was sat reclining in his chair he turned his computer turned to face Harry. "Harry Potter AKA the fox, the world's greatest thief"

"World's greatest thief huh?" He said leaning back with his arms behind his head "Think I could get that on a t-shirt" he asked Henry back.

"You know you're pretty calm for someone caught red handed" He sounded so confident and sure that Harry laughed, he caught the Doctor studying his wristband and Rose was frowning at him as though she were working him out "Look Van Statten, I broke into your supposed secure base with as much effort for me to open a can of coke" Harry said all serious now looking at Henry Van Statten in all of his vain glory "Do you really think you scare me"

"Hmm true, Alan!" he called and the stern guard from before walked in, Van Statten waved his hand to him and he found himself sat in front of a man with a gun. Clearly done with him, Henry turned to the Doctor, whoever he was, and said "So you seem to be the expert, but the question is, how you got in? Fifty three floors down, with your little cat burglar accomplice. You're quite a collector yourself, she's rather pretty"

"She does gonna smack you if you keep calling her she!" Rose snapped at him and Harry smirked at her, she gave a sort of smile back. He called it a win.

"Oh and she's English too, got yourself a little girlfriend Lord Fauntleroy"

"This is Mr Henry Van Statten" The Weedy man said and Harry felt distinctly unimpressed by him. He seemed easy to be swayed by temptation "And whose he when he's at home" Rose asked

"Mr Van Statten owns the internet" the weedy man said

"Don't be ridiculous, no one owns the internet" Rose scoffed and Harry nodded, making the man frown "Nah he doesn't, He just likes to put on airs to make himself feel all manly" Harry snarked and Alan, as the guard had been named, prodded him with the butt of his gun. Rose coughed, covering a laugh and he could see the Doctor smirked, "There's one thing I got to ask Van Statten, even when I was scoping out your little man cave here, there's that thing called the cage…What the hell is in it"

"Like you don't know" he said "The great thief and he doesn't even know" Harry scoffed at the man.

"I look for valuables, stuff I can hawk at a later date. Whatever kinky lab stuff you got going on wasn't my priority, can't make money from it" he gave a breathless laugh "But since I'm all tied up, you've piqued my curiosity, so tell me what you got hiding down there" Van Statten smirked and looked this time at the doctor "The cage contains my one living specimen"

"Show me" The doctor demanded and Henry smirked, all of his small stained teeth showing under his slug like moustache "You want to see it"

"Show me" the doctor said again and Harry shifted in his seat

"Well, you can just smell the testosterone in here" Rose joked and Harry chuckled drawing her attention to him "Goddard inform the cage we're coming down, Alan take Mr Potter here to the cells near the cage until the FBI can be called, You" Van Statten pointed at Adam "Take the girl and do whatever it is that you British do spoon or canoodle or whatever"


And that was how Harry found himself inside of a cell, again. Course it was nothing like the ones in Rome, they still used the chains. Alan, his personal appointed guard, was hunched in the corner polishing his gun, no entendre intended there. He leaned back in his chair, his cuffs clinked against the wall, there was a vent in the corner, and it was big enough for him to slip through showing once again the ineptness of Van Statten's supposed high tech security. He glanced at Alan who seemed to completely disinterested with him, he stretched back reaching into his hair for his bobby pin. Slipping it free and placing his hands in between his knees and out of Alan's he set about freeing himself from the cuffs.

The Doctor watched in Horror as the Dalek broke free from the chains holding it's position in the cage, the as it consumed and eventually killed a, while not innocent, doctor. The camera flicked to the outside of the cage, Rose's face came onto the screen. Her normal pretty face was twisted in ear and the doctor felt a tendril of guilt in his chest, she was so young. Too young "I'm sorry Doctor, it was my fault" She said and he tried to smile comfortingly at her but in his mind he knew the reality, A Dalek wouldn't stop, couldn't stop. It was a killing machine, no remorse, no guilt, nothing but hate. "I've sealed off the compartment, it can't get out that locks got a billion combinations"

"A Daleks a genius, it can calculate a thousand billion combinations in one second flat" The Doctor said, behind the Guard he could hear the Vault door crack open and he groaned in anger, he hated them. In that moment he felt such a rush of pure unadulterated hatred towards the being currently butchering the soldiers below, he wanted it gone. "Don't shoot it!" Van Statten shouted at the team leader "I want it unharmed" ignoring the stupidity of the man next to him he tried to catch Rose's attention "Rose! Get out of there, now!" she nodded and her face left the screen "You need to move harry as well"

"Good point" Van Statten said turning to Goddard "Tell Alan to get out of the cells, leave Mr Potter"

"You're condemning him to death!" The doctor snapped when he had first seen the boy he could almost feel the potential in him, much like he had when he had first met Rose. "Thieves die all the time" He said callously, when a power surge made the Doctor look back at the screens "What…What's it doing" Goddard asked as the Dalek screamed, one of its weapons imbedded in the server "It's downloading" The Doctor said horrified as it eventually stopped, the metal surrounding it becoming shiny and new, "Downloading what?" Goddard asked as Van Statten continued to bark orders to the soldiers in the compartment "Everything, in one second that Dalek has just downloaded the entire internet and the eastern seaboard power supply" The Doctor snapped "You have to kill it, now!"


"Alan, leave the cage and the prisoner and help with the incident outside" A voice in Harry's guards walkie talkie sounded "But Sir, what about the Prisoners safety" Alan glanced at Harry, who smirked at him, he didn't realised he cared "The Prisoner is not the Priority, eliminating the threat in the containment cage is the priority"

Harry could see Alan's reluctance before his training kicked in, he stood and cocked his gun; as he let the room he cast one last look at Harry before sweeping out. The second he left, Harry jumped to his feet and climbed on top of the table using the bobby pins flat edge he slowly began to unscrew the sides of the vent. When he heard the sounds of fighting and screams from outside the door, he desperately tried to unscrew it quicker. When it finally clattered to the floor he could hear the whirring of whatever Van Statten had kept inside the cage, the thing that had mowed down nearly all of the compounds guards. He slipped into the metal vent and clambered away hoping to lose whatever it was.

He crawled through what seemed like miles and miles of vents until he reached an upward facing vent shaft, he didn't have his harness or his climbing gear. Sighing he dug his fingers into the grooves on the side and heaved himself up, in his head he did a mental calculation that to reach Van Statten's office and find whoever the hell this 'doctor' was, he'd have to climb over 1,000 metres of ventilation shaft. He shook a bead of sweat from his forehead; it was going to be a long climb.


"Because it honestly believes they should die. Human beings are different, and anything different is wrong. It's the ultimate in racial cleansing and you, Van Statten, you've let it loose! The Dalek's surrounded by a force field. The bullets are melting before they even hit home, but it's not indestructible" The Doctor ranted before instructing the men, civilians, anyone with a gun how to kill the machine. He had now once again lost sight of rose and if it weren't for the layout of the compound showing her signature on the map, he'd have no idea where she was. "Sir, something's climbing the ventilation shaft" Goddard said and the Doctor rushed over, Van Statten close behind.

"How long till it reaches us" Van Statten asked his voice wary and afraid- something the Doctor himself almost mirrored. "Now" She answered and the grate above the desk popped off, a foot dangled over the edge before it slipped down revealing Harry stood smiling as though nothing was wrong "What…How…" Van Statten mumbled before harry smirked at him, his green eyes flashing

"What am I doing? Well that thing you kept in the cage got loose and I'm not one to wait around to die" He answered "How, well you did call me the world greatest thief" He said and the Doctor grinned at him "So what's the sitch"

"An unstoppable killing machine housed by that idiot" The Doctor said pointing at Van Statten "Has escaped; Rose is still down there with what's-his-face"

"Always knew you were all money but no brain" Harry said picking up an expensive looking paper weight and pocketing it, "What the hell did I ever do to you" Van Statten asked Harry who shrugged, sitting back on the chair putting his feet up "Don't take it personally, it's not just you" Harry said looking at Henry Van Statten head on "To me you're just another pay check, with all the Alien tech you have down there it would have been a pretty good one too"

"Who to" The Doctor asked him

"What do you mean, who to. Black market sales men take all kinds of stolen art work and with the stuff he's got packing in here they'd be all over it"

"No, the at work I get but what about the Alien Technology, who's gonna buy that" He asked and Harry smiled at him "I got contacts, course not all of them are down here" He said tapping his wristband "Found this in an army base, they couldn't work out what it did but I sure as hell did"

"It's a teleporter, that's how you know so much about Aliens and the universe, cos you've got a little universe Jumper right on your wrist, one button and off you go"

"Exactly" harry said smiling widely, but the Doctor frowned at him

"But it's wrong" The Doctor said, pulling out some kind of long metallic tube form his jacket "That wristband tears a whole in the fabric of the universe for a split second, long enough for you to push through but it's creating cracks in space and time, nothing can do that"

"Which means what exactly" Harry said picking at the straps of the wristband, it had begun to feel uncomfortable on his wrist, no matter how useful the thing was in procuring Alien tech the fabric of the universe seemed to be a hell of a lot more important than any pay check could be "Eventually the cracks will grow, the universe will begin to push them wider, realities will begin to bleed into each other and the universe as we know it comes to an end" The Doctor said looking at Harry intently as though judging him for what his next move would be, Harry tugged the leather strap off his thin wrist and said "Stupid thing clashed with all my shirts anyway" and tossed to the floor, stamping his foot over it until it was crushed beyond repair. He smiled and jumping to his feet he said "Now, about getting out you said that we can seal the vault"

"This place was supposed to be a nuclear bomb shelter, those doors are reinforced steel at least six inches thick" Harry rolled off

"There's not enough power, those bulkheads are too big"

"We have emergency power, we can re-route tem to the doors" The doctor suggested but Goddard shook her head her curly hair whipping across her face "No, we'd have to bypass all the codes, it would take a genius"

"Or it would take me" Van Statten said sitting at his own computer

"You want to help?" Harry asked disbelieving of the self-serving man.

"I don't want to die" He said and Harry nodded,

"Careful Van Statten for a second I thought you had a heart" Harry snarked at the billionaire, who glared at him in front of him, the metal thing appeared on the screen "I shall speak only to the Doctor" it spoke in its tinny metallic voice, the Doctor looked at him and Harry shivered the look on his face was almost murderous "You're going to rust" The Doctor said as the Dalek remained stationary in the face of the fire sprinklers. "I fed off the DNA of Rose Tyler, the Biomass of a time traveller has allowed regeneration" It spoke, it's golden body glinting in the dim light.

"And for your next trick" The Doctor spat out angrily

"I have been searching for the Daleks" It said and the Doctor gave a humourless laugh once again glaring at the metal thing, A Dalek, "Find them did you"

"I scanned your satellites and radios and found….nothing" It said this almost sadly, Harry felt sorry for it. He knew all too well what it meant to be alone in the world, "Where shall I get my commands now" It asked the Doctor "You're just a soldier without commands"

"Then I shall follow Primary command for the Dalek Race" It said "Destroy and Conquer"

"But what for, what's the point? Don't you see everything you were everything you stood for it's all gone?"

"Then what shall I do" It asked again and the Doctor froze for a moment and then he slowly spoke, in a quiet dangerous voice "Die" Harry spun to look at him "finish the job! Make the Dalek race extinct rid the universe of your filth, why don't you just die!" He shouted at the thing, nothing was said and Harry squirmed in the uncomfortable feeling in the room "You would make an excellent Dalek" The Doctor mouth dropped, only minutely but harry knew how to read people, the Daleks words had chilled him, no matter how much he would try to deny them "Seal the vault" The Doctor said breaking the silence finally "But, but your friend is still down there isn't she?" Harry asked him and he nodded, rubbing a hand across his face "I know, but if that Dalek gets out it will kill every man, woman and child in the entire world" He said, Harry stood and rested a hand on his shoulder, he looked at Harry who looked at him, trying to look sympathetic, The doctor grabbed Van Statten's office phone dialling a seemingly random number, he put it on speaker phone and Roses voice broke through "Not really the best time" She sounded out of breath and the sound of feet pounding concrete echoed through the speaker "Where are you right now" He asked desperately

"Level fourty two" She said and the Doctor sighed looking over at Van Statten who was still typing rapidly on his keyboard "You need to Hurry, the vaults being sealed off at Level Fourty six" Rose panted harder "Can't you stop it" She asked

"I'm the one sealing them; I can't let the Dalek loose, so for God's sake hurry up!" He said, behind them Goddard said "It's right behind them"

"The powers at the bulkheads, we can seal them" Van Statten said leaning back with a smirk on his face "God it's been years since I had to work that fast"

"You're enjoying this aren't you" The Doctor asked, the speaker phone crackled again and Rose's voice broke through "We're nearly there, give us two seconds"

"I can't hold them up for long" Van Statten said "You have to seal the vault now" The Doctor looked indecisive before his hand hovered over the enter button "I'm sorry" he clicked it and a klaxon blared around them. "It's done its sealed" Van Statten said and the Doctor dived to the phone

"Rose?" He asked "Did you make it, Rose!" there was a second of silence and harry felt his heart constrict at the face of the Doctor, "I was a bit slow…Sorry" She eventually said, her voice shook as the Dalek rounded the corner "I guess this is it. Doctor, this wasn't your fault! Remember that okay? It wasn't your fault" She insisted and the Doctors face twisted in grief as she took a shaky breath "And you know what? I wouldn't have missed it for the world"

"EXTERMINATE!" a zap of something and it all went dead. The Doctor dropped the phone, Harry felt bad for him, and he really did. This Rose girl was clearly important to him, very important "I killed her" He said and Harry looked at him "No you didn't" he said and the Doctor spun to him with fire in his eyes the lines around his mouth tightened "I promised to take care of her, I promised"

"I'm sorry" Van Statten said but it sounded hollow to Harry's ears

"She was only here because of me and you're sorry!" He snapped to the man who leaned back as the Doctors anger rounded on him "I could've stopped this, I could've killed that thing in its cell but you stopped me!" He all but shouted at the man

"It was the prize in my collection!" Van Statten said back as though that absolved everything that had happened down there, Harry felt his blood boil "And that makes it okay! All those men died, Van Statten, they died! How many had families down there? How many kids will never see their parents again?" Harry asked him standing with his hands balled into fists

"Was it worth Van Statten? All those men? Rose's life? Let me tell you something Van Statten, mankind goes into the universe to explore, to be part of something greater" Van Statten's moustache began to quiver as he took in the two angry figures in front of him and the disgusted face of his assistant Goddard "That's what I wanted! I wanted to touch the stars" Harry scoffed, the Doctor shook his head giving a sardonic smile to the man "You want to drag the stars down, stick a label on them and lock them underground underneath sand dirt and concrete. You're about as far from the stars as you can get and you dragged her down with you!" He snapped again "She was nineteen years old"

Behind them, the weedy man Adam ran in, he stooped down sucking in lungful's of breath greedily, "You were quick on your feet, leaving Rose behind" The Doctor commented

"I'm not the one who sealed the vault here" Adam retorted and Harry scoffed

"No but you are the one who took a civilian down to a sealed area to get a leg over" He put in, the man glared at Harry who smirked in response, no humour when he did so. Before the man could reply, the monitor behind them crackled before it opened revealing the Dalek "Open the Bulkhead or Rose Tyler dies" It ordered and the Doctor gave a short breathless whoop of joy

"You're alive!" he said and Rose on the screen gave a small smile, though it was more of a grimace "Can't get rid of me" She tried to joke but Harry could see the small tremors in her body as she stood next to a killing machine. "Open the Bulkhead" The Dalek demanded again.

"Don't do it!" Rose shouted, seemingly uncaring that the thing next to her could kill her.

"What use are emotions Doctor, if you can't save the woman you love" It asked him and Harry could see the conflict inside of his head "Doctor" He said quietly and the man turned to him "Do what feels right, ignore everything else" He didn't know if that helped him in anyway but it was all he could do "I killed her once, I can't do it again" He said he pressed the release button, the screen went black and Harry's hear thudded in his chest, usually when the going got tough he legged it, he didn't stick around. "What do we do now?" Van Statten demanded of the Doctor "What the hell do we do, you bleeding heart"

"We kill it when we get here" Adam suggested and Harry nodded approvingly

"How? All the guns are useless and the Alien technology is in the vault" Goddard said

"Only the non-catalogued ones" Adam said to him, and when the Doctor nodded he gave a wide smile, before leading them to his workshop.

"Dear god, I'm in the belly of the nerd monster" Harry said, he walked to Adams desk and opened a few drawers- there wasn't anything that valuable but he pocketed a nice looking watch and a few bags of what he assumed to be office petty cash. In the corner he overheard the Doctor and Adam discussing what he'd do if he were to be replaced in Van Statten's service. Harry rolled his eyes when he mentioned how he'd fight his way out, the weedy man wouldn't stand a chance. "Oh yes" The Doctor said holding a gun looking thing up "Lock and Load" he ran out of the room, Harry followed behind while Adam began to load all the discarded stuff back into the box grumbling as he did.

Harry watched the Doctor run ahead, brandishing the gun wildly, he turned and headed back to the cupboard where he had dumped all his gear, he knew that Van Statten had contacted the FBI and they would be here in a matter of hours, he rather get a head start on them before they could catch up to him. While he could bust out of the cuffs no problem, he'd rather not have his face blasted all over the world.

He had already taken his bag back from the office; he walked into the supply cupboard and grabbed his second duffel bag from the floor. "-Good thing I'm not going anywhere then" Rose's voice drifted through the open door "Yeah" The Doctors followed, shouldering one of them and dragging the other one behind him "Alright harry" Rose said smiling slightly

"Hello, so I guess this is it for Van Statten" he said

"In a matter of hours he'll just be another faceless man in the city" The Doctor replied

"What about you, where are you headed"

"Well, I'll have to go find a buyer for this stuff" Harry said "After that I guess…I'll just keep travelling" He shrugged, he didn't see Rose glance over at the Doctor with a look until the man sighed and said "You know, if you were just wandering we could always use another person on the TARDIS"

"What exactly is a TARDIS?" He said as the two walked into a blue box, "Er, I know that Van Statten has an obsession with history and stuff but how is that gonna fit all of us"

"Trust us" Rose said and she walked in after the Doctor, the door shut loosely behind her. Harry reached out his hand, and touched the wood, which seemed to be humming under his fingertips. He spied Adam from the corner of his eyes, taking a deep breath; he pushed the door open and walked in, shutting the door behind him.

"No way!"
