Chapter 1-

The day was cold, the first day of December, when advent calendars were open, and the nights got colder than the days. Jamie Reagan was still asleep at half seven in the morning having taken a late shift the night before, thankfully Jenna the English Language student who went to the local community college had the evening off making it easier for him, to work. Suddenly there was a large thump and Jamie was awoken from sleep by something heavy and giggling bouncing on his bed. Rolling over and narrowly avoiding a knee to the ribcage Jamie turned to see his little five year old daughter Katy sat on the bed in her unicorn pyjamas clutching her stuffed unicorn, blonde hair messed up in a way that would have been irritating had it not been Katy.

Sitting up and waking up because Jamie had learned the hard way that once Katy was up then that was it she would stay up. Especially in December when there was only a few weeks till Christmas and Katy was counting down the days on that stupid calendar that Erin had thought it would be funny to buy.

"Hey Katy-Kat" Jamie muttered sitting up and pulling Katy and her unicorn on to his lap. "Helwo Daddy" came the small mutter back. Hoisting Katy up on his hip the young cop and father walked down the hallway of his apartment into the kitchen.

Sitting Katy on one of the high bar chairs at the little island, he then busied himself by making a coffee for himself and pouring a glass of milk for Katy and putting some toast in the toaster.

Katy Margret Reagan was the only daughter of Jamie Reagan and Eddie Janko, and one of the products of a confused one night stand born on one rainy night in November. Eddie had died in a 10-13 when Katy was just a baby and the killer had been put away for life leaving a younger brother who had stood in the court in shame. It hadn't been easy being a cop and a father all at the same time but Jamie had been lucky enough to find Jenna one of Nikki's friends who was studying locally and lived nearby to look after Katy when he was at work in exchange for money for her tuition and carpooling fees. Katy was now five a little blonde haired, blue eyed dervish that could change from little angel to little devil in the blink of an eye. Katy was generally a sweet kid but could somehow manage to manipulate the entire family to do whatever she wanted no matter what, which was great for Danny who seemed to enjoy being the "fun" uncle no matter what happened including feeding his daughter enough chocolate to ensure that sugar rush kicked in which was beyond brutal.

Jamie watched as Katy chomped down two slices of buttered toast and chugged down a mug of milk before hopping down off the chair and pattering off to her room still clutching her unicorn. Jamie checked his watch and right on schedule the buzzer chimed signalling Jenna's arrival. Jenna was responsible for taking Katy to and from school, and looking after her at night when Jamie was on the shift. Letting Jenna in Jamie went off to get ready and came out in his uniform to see the petite eighteen year old sat at the counter a stack of books next to her.

"Morning Mr Reagan" she said smiling brightly. "Morning Jen" Jamie said smiling "and I've told you to call me Jamie" the girl smiled again, then rolled her eyes "slight change today if you don't mind Mr Reagan, I got a mock exam this afternoon so I might be a bit late picking up Katy should only be half an hour but I'll let the school know."

Jamie smiled-the girl was really too sweet for her own good. "That's fine, I'll be up at the 12th until six so if you could take her till, then that be great- there's some leftover Chicken Casserole in the fridge and fix yourself a plate up too- I'll catch something when I come in" Jenna nodded and Jamie grabbed his gun before walking into Katy's room.

"Hey Katy-Kat" he said bending down and helping her with her tie, it was no good tackling her hair that was best left to Jenna who also had to battle with the unicorn who Katy insisted was the best thing she had ever-owned, and should therefore be taken everywhere no matter where "there" was and never be washed.

"You know the drill remember Jenna takes you to school but today she's gonna be a bit late to pick you up so you don't leave the school without her ok?" Katy nodded once, blue eyes round, serious and yet completely innocent. Jamie grinned before leaning forward and pressing a kiss to her blonde hair before wrapping her in his arms.

"Love you Katy-Kat" he muttered seriously "Love you too Daddy" came the reply. Placing another kiss to his daughter's mess of blonde hair, and smiling at Jenna on the way out, Jamie went to work.

He watched Regan leave, from the side of the street uniform all crisp and neat like the day he had been in court and gave his older brother a life behind bars branded a cop-killer with little chance of parole. He could see from the top of the apartment the nanny brushing the little girl's hair into a French plat. The girl was an exact replica of her father and that just made his blood boil. But he had a plan, today he would extract revenge on the man that had ruined his brother and his family life. He was going to make Reagan pay through the one thing he would put down his life for. His daughter.

On the cold day that was December 1st Jason Callan brother to Lance Callan the infamous cop killer of Eddie Janko, made a promise to himself and his brother. Today Jamie Reagan would pay.
