Disclaimer: I don't own anything that didn't come from my own imagination.

A/N: Exams at the moment so updating will probably be pretty slow for the next two weeks. Wasn't planning on posting this till I had more chapters written but need so motivation tbh. Anywho hope you enjoy and reviews are much appreciated, even the bad ones if they're constructive. Sorry that this is so short, I promise the chapters themselves will be longer.

Prologue

'Who can hope to be safe? who sufficiently cautious? Guard himself as he may, every moment's an ambush'-Horace

J.J slammed the door behind her, throwing her keys on the phone table as she passed. It had been a long day and a hard case that she didn't want to revisit again. She needed a stiff drink and a long sleep. She hoped they might have some time off tomorrow but she doubted it, she was the one who decided the cases and she knew there would be a fresh pile of files on her desk by morning to add to the towering piles already stacked all over her office.

She paused in pouring herself a large glass of wine and glanced around her, her hand going to her holster. The house was silent except for the ticking of the clock as the hour hand slipped closer to two. The streets were empty, both doors were locked and garden was surrounded by a six foot wall and a heavy metal gate which was permanently padlocked. Her mind was simply playing tricks again; she still wasn't used to living alone. As she swallowed her glass of wine in one she tried to figure out when she next had vacation time and if there was any way to move it closer. She needed to see Henry soon, she hadn't seen him enough before, now that he lived in a separate house, in a different state, it was torture. She poured and downed a second glass before heading upstairs.

The streets were silent and empty so no-one noticed the unmarked black sedan parked slightly up the road from J.J's house. No-one witnessed the expression of annoyance that flashed over it's inhabitant's face when the master bedroom's curtains closed or how it changed to a smirk when the sliver of light visible between the curtains went out. No-one noticed that after a tense twenty minutes the sedan drove off carefully and no-one realised it's departure was prompted by the four brief torch flashes the came from the master bedroom window.
