Before you start, please read below, don't just skip down to the start of the story, k?

I had this very random idea for a fic here, it could work, it might not. Let's find out.

I don't own the rights to Life on Mars, but I do own this story, so, well, you know the drill.

Ok, here goes.

Meet Christy Tyler, Daughter of Annie and Sam Tyler. Born 1978, two years after Sam and Annie got married. She's head-strong and kind but also has a quick temper, a bit like her mother in that respect! She's followed in her parents' footsteps and joined the force after getting a Degree in Chemistry. Although born in Manchester, when she was four the family moved to York when Sam was offered a DCI placement in the CID there. Now 28 and a DS in the police force in York's forensic squad, she decides to return to the action of the city on a transfer to Manchester's A Division CID. She thought it would be a new experience, but she didn't know what was coming…

(Please bear with me; I wanna do a little bit of scene setting first off. K?)
(Oh and just before you get totally confused, the first bit is set before even the first ever episode starts!)
PPS in this fic, Annie knows, and believes that Sam is from the future. (This is a sort of sequel to One Way Ticket, but don't look at it like that).

Seeing Double

Sam

He'd been getting nowhere all week. Forensic evidence up to the department's eyeballs yet not even that and Manchester's finest CID squad could crack this one, death by bootlace with no obvious motives, just what he needed. Sam scoffed at the thought, he had other problems. Like the immanent arrival of a new DS, Christy Tyler. Sam smiled at the thought of being able to take another female detective under his wing, like Maya. "Sam, case reports on the West cliff road robberies, a cuppa tea, bourbons." Speak of the devil Sam thought as Maya breezed in.

"Ta, has that new DS arrived yet?" Sam asked leafing through the case file he'd been handed. For him paper files were now a rare occurrence with almost everything automated, but he did find they were easier to lay your hands on. Maya shook her head to his comment and turned to leave as quickly as she'd come.

"Maya." Sam said as she left but she didn't hear, and with sudden defeat buried his head in his hands.

Sam didn't enjoy the rest of the morning much either. Yes, he loved his job as DCI, but sometimes he felt like it was weight he could do without, especially where relationships where concerned. Another thing he'd rather not think about. Suddenly the phone on his desk rang with a shrill tone making Sam jump. "Sam Tyler." Sam said hoarsely.

"DS Christy Tyler is down here sir, shall I send her up." A muffled voice can over the intercom phone.

"Yeah, cheers." Sam said before hanging up.

Christy

"CID is on the 3rd floor, can you make your own way?" Said the rather officious looking WDS who was manning the front desk. She'd just called up, who Christy could only assume, was going to be her knew boss. Christy nodded, she'd like to make a good impression, and being able to stand on your own two feet in a new place was the best piece of advice her dad had ever given her. The WDS cocked her head towards one corner of the area, showing where the lift and stairs where. Christy decided on the stairs, she'd need the time to compose herself.

Come to think about it, she was wondering why she was so nervous. When she'd told her mum she was overjoyed that Christy could even be offered a job at A Division. Her dad, oddly, wasn't at all keen, and consonantly checked calendars and dates, as if trying to remember something, while shooting Annie, all the while, ever more meaningful looks. Christy had over heard an odd conversation erupt from the sitting room when she had go to the kitchen to make more tea.

"Sam, we've been over this a thousand times! So what if she meets, well, you. Can you remember?" Annie whispered in low tones.

"Well, to be honest, I was a bit dazed the week before the accident. I don't recall. You know my memory of back then is slipping." Sam muttered back, "I never told her, you know that. Only you knew, Annie."

"Maybe you do owe her that much."

"Only when I know that I've gone." Sam whispered. They stopped, almost as if they had heard the approaching footsteps from down the hall.

And then Christy walked in.

Christy ran her hand along the wall as she walked up the flight of stairs. Not even just over thirty years of new magnolia paint could quite cover up the nicotine stains from when her mum and dad had worked there all those years ago. Soon enough Christy found herself in a large open plan office space with a pre-fab. office at one end. The whole room was blindingly bright, awash with whites and powder-blues, which reminded her greatly of cornflowers. Spotting the closest desk with an officer stationed at it she walked over boldly and asked for directions to the DCI of the department.

The friendly face of DC Mark Swift, resident of the desk, gave Christy directions to the end of the room and to the pre-fab. office after introducing himself. Christy smiled in return and headed over to the stripped one-way glass door.

Sam

Sam heard a knock on his door, oddly similar, if not identical to his own.

"Cum'in"

Sam said though a mouth full of bourbon. No response. He swallowed hard,

"Come in!" he said a little louder and eyed the doorknob as it turned.

The woman who walked in looked truly lovely. She had darkish sandy brown hair cropped short with a wispy fringe that fell into her chocolate brown eyes. She wore a pinky coloured blouse that deliberately nipped in at the waist showing off her hour-glass figure. She wore deep espresso trousers, so dark they where almost black and black heels. And to finish the look, swung over her shoulder was a whisky coloured suede jacket. She radiated cool, and only her eyes, alert and sparkling gave away any tinge of nervousness.

"DS Christy Tyler." The girl said with a smile offering her hand across the desk. Sam brushed his hands together to get rid of the crumbs on his hands and offered his to her in return.

"DCI Sam Tyler." Sam said shaking Christy's hand. Almost instantly Christy's face fell and her eyes widened.

Christy

She couldn't let go of his hand. This man with the dead ringer of her father, more so. Identical. In his speech, his mannerisms, even choice of chocolate biscuit! But it couldn't be, it just couldn't be…

Sam and Annie

"DS Christy Tyler." The girl said with a smile offering her hand across the desk. Sam brushed his hands together to get rid of the crumbs on his hands and offered his to her in return.

"DCI Sam Tyler." Sam said shaking Christy's hand. Almost instantly Christy's face fell and her eyes widened.

The memory struck as if it had only freshly been thought. "Annie." Sam whispered across the room to Annie who was reading a book.

"What is it?" Annie asked saving her page and moving over to him.

"I remember."

Well, let me know what you think so far. I'm only going to keep it divided into 3 POVs as it could get confusing. Well, it's set to be anyway. Just to clarify, Sam and Annie are the Sam and Annie who are in 2006 and are Christy's parents.

Cheers for reading, chapter 2 soon.
