Disclaimer: don't own-ah well. Truly I will one day have my own category and won't have to write this any more

Right so. This sprang into my head quite of it's own accord-hopefully I'll get to finish some of my other stories, but I've been watching far too many murder mystery cop things lately-and though I'm crap at writing them I decided to give it a go.

This story is AU, set in the normal, everyday, non-wizarding world. This may well turn into a slash, knowing my string of luck with Draco and Ron. As this is an AU, I will give you some history and character stuff, though don't expect an update for a while.

Ron Weasley-- a detective/cop type person. This is his story, so I can't give too much away.

Draco Malfoy--the new detective at the prescient, and Ron's new partner, also the son of a man suspected of being in cahoots with crime boss Tom Riddle, aka, Voldermort.

Severus Snape-- undercover agent working in Voldermort's operation, trying to find out anything that can bring the crime lord to justice. Ron believe he is a double agent.

Hermione--the forensic scientist, and Ron's crush, basically all she does is cut up bodies and tell him icky squicky facts, and refuses to go out on a date with him.

Percy/Oliver--another police team (can't you just imagine it?) who occasionally help out and make random appearances.

Dumbledore--the police chief.

Harry Potter--Ron's old partner, dies in the first chapter (what, I hate Harry!) had a major chip on his shoulder against Voldermort because of a bomb that killed his parents.

Sirius--Severus' liaison with the police force, though they fight they work well together, Sirius making sure Sev doesn't go too far under.

Remus--he just kinda appears at random intervals. Used to be a cop, and Sirius' partner, but unfortunately was injured, but he occasionally helps out.

Yes I know, confusing. But if I tidy it up it might actually be good. Lol.

Remember to review.

Prologue

Gunfire erupted suddenly, giving the red haired man barely enough time to dive behind the merge shelter of the patrol car door, grasping with one hand for the radio dangling on the cord, swinging serenely just inches from his grasping fingers, slamming his gun down on his knee, locking and loading as efficiently as he could. His questing fingers finally made contact and he quickly pulled the radio over to him quickly, pressing the button.

"Officer Ron Weasely, requesting backup, Number 5 Eglinton rd. Gunfire, officer Potter's status unknown." he said in as calm a voice as he could, grimacing as a bullet sheared through the car door very close to his head.

"Backup on the way Officer, just hold on." Mavis, the communications officer told him in her reassuring way.

Officer Ron Weasely didn't respond, but threw the radio back into the car, twisting until he could see where the shots were being fired from, raising his gun he snapped the safety off, aimed and fired in the most likely location before he made an undignified scramble to the back of the car as an explosion of bullets rained down around him. All he could hope was that his best friend and partner was alive in this madness.

He wasn't sure how long he had spent ducking around the car, dodging bullets, waiting for the damned backup to realise it was a bloody emergency and get here, keeping an eye out for his partner. But he hadn't seen sight nor sound of Harry since he had entered the building. He had stayed outside on Harry's request-after all, it was supposed to have been a routine check-up at the house. An anonymous tip about some druggie teenagers.

A few minutes and hundreds of bullets later he heard the sound of sirens coming closer. Thank god. There just might be a chance now. He fired off a few more rounds, knowing it was useless. He couldn't see who was firing, or from where exactly. He heard the other squad cars pull up and ducked back down, turning to motion the other officers where there was an almighty explosion from behind him. Eyes wide he turned.

The building was on fire, smoke billowing out of the windows. All shooting had ceased.

All Ron could do was stare at it, shocked into immobility, one thought flashing to the forefront of his mind.

"Harry was in there!"

He felt himself be jerked back by another officer as another explosion rocked the building, sending a shower of flaming debris flying out to land on this car, which smouldered for a moment before the fire caught on some petrol that had leaked when a bullet had hit the gas tank and the car joined the building in an explosion of fire.

There was little they could do but call for the fire brigade and try to keep the onlookers who had gathered back.

There was no way anyone could have survived that blast.
