A/N: Hi, I'm Meg. I'm pretty new to this writing business, even though I have been reading fanfics for ages.

Anyway, so I have been searching for AU where Cas and the whole angel garrison are law-enforcement officers. But I was really disappointed when I couldn't find a single one. So, I decided to write my own fic. =)

Just some info, I do not know sh*t about behavioral analysis other than what I have learned from cop shows on TV and such. And also I don't know how the police work in the US. I am totally basing it on how the cops work in my country(which is India). So, maybe some part may seem weird to you guys.

Anyway I really would like to improve my writing, so please review and tell me how I'm doing. And if you want to know something related to the story you can PM me.

(This is the edited version of the original chapter).

Thanks to Brooke for pointing out my mistakes.

Disclaimer: You honestly think I would write fanfics if I owned Supernatural?

Chapter 1

Castiel huffed. He was dog-tired and beyond frustrated. And on the very first day of his job, he was on the verge of reconsidering his career choice.

15 Hours Ago

It was 8.30 a.m. when the newly-passed-out-from-the-academy rookie Castiel Novak reported for duty. It was cheerful, sunny and, in general, a nice day. And Cas was quite excited. A small grin was ever-present on his decidedly handsome face. Because all the hard work he put into excelling at the Academy was finally paying off. He desperately tried to look serious as he opened and walked through the huge double doors of the station, his back ramrod-straight and head held high.

The room he entered was basically a huge open room with desks strewn all over the place. Several doors on the sides led off to different sections of the station. Police personnel were moving around chaotically, most carrying sheaves of paper and files. The room was humming with conversation. Occasional cursing and shouting could be heard from the adjacent holding cells, which were separated from the room by a door. The atmosphere was relatively relaxed, a stark contrast with the rush during the day.

From the lobby area, a stair spiraled up, leading to a long balcony. Several rooms with (bullet-proof) glass walls led off from the balcony. These belonged to the superiors, the forensic labs, the briefing room and occasional task force gathered in the station.

No one spared him a single glance as he made his way through the people. Cas's spirit dampened a bit. He expected that people would at least look at him, nod at him or something! Something to show that he would be accepted as one of their own- but they didn't. But he shrugged lightly to himself and tugged at the black leather satchel he was carrying, and made way to his destination. The lieutenant's office.

The door of the room boldly proclaimed 'Lieutenant A. Milton'. The inside of the room was clearly visible to Castiel. There were three persons in the room. A red-head woman in a black pant suit, a uniformed police officer and a short blonde man in a tan jacket. The woman was leaning against the far wall, the man in the jacket sitting was on the huge desk on the side of the room while the other man was sitting in the comfortable-looking leather seat on the other side of the room. They were looking at a LCD screen that was placed directly opposite to the door. The screen was currently showing the face of a man, it was heavily pixelated, probably from a cheap CCTV camera in some shop. Some other papers were also on the background; Castiel could only guess they were the man's criminal history.

Castiel took some time to compose himself before he opened the door to the room in one swift, confident motion, not bothering to knock. The door gave a small damped creak as it opened and three pairs of inquisitive eyes immediately snapped to look at him. Cas was pretty sure they got whiplash from how fast their heads turned. The gazes softened when the people recognized who it was.

A small welcoming smile spread on the woman's face. "Hey lil' bro!"-she checked her watch- "and right on time too! Nice."

The last part seemed directed to the guy in a jacket. Who smirked before coming and hugging Cas.

"Hey bro", he pulled back and spread his arms in a welcoming gesture and then added, "Welcome to the 15th Division".

A small grin found its way to Cas's face as he muttered a small, "Thanks Gabe".

He turned to look at the third person in the room who nodded at him with a small smile. Cas did the same.

"So what's going on here guys?", the rookie ventured looking at the screen.

"Oh just that another criminal wandering the street again, all thanks to, yes, you guessed it right, the highly functional FBI!", Gabe said with a flourish, the mocking tone in his voice evident.

"I think you are seriously underestimating this guy. You have seen his rap sheet, right? He has got pretty much everything under his belt! Including three counts of first degree murder. And not only has he escaped from the police and FBI innumerable times, he has also broken out of a super-max facility once. He is definitely not your petty criminal, this guy has some serious skills.", the uniformed guy said, he was clearly impressed.

"What do you think is this guy? Modern-day Houdini? Pfft, come on, he so had inside help escaping the super-max. And. Okay, he is good at his game. I will give him that. But that is all he is, a pay-for-hire goon." ,the blonde shot back, hands on his hips.

"I actually tend to agree with Michael on this one. This guy is smart. Smarter than our general bunch of gun-toting criminals. ", the red-head said.

Gabriel rolled his eyes exaggeratingly at this. The woman ignored this and continued, "But, thankfully, this time our source is dependable. He is coming downtown tonight to seal a deal apparently. However, we have no intel on what deal it is. Could be anything ranging from drugs to weapons. We are confident that he hasn't been tipped off. So this is our only chance to put the elusive bastard behind bars."

Castiel's blue eyes widened at this. His sister swearing was not something he was used to. Actually he had never heard his sister swear before. And somehow it didn't just sound right coming out of her throat.

Gabriel, noticing Cas's expression, patted him lightly on his back. "Get used to it baby bro. Lieutenant Anna Milton is a totally different person from our sweet sister An.", a small wink followed.

"Oh shut up Gabe!", Anna snapped, "and sorry Cas, I really don't know what else to call these people".

Cas mumbled a "It's 'k", busy staring at the screen and absorbing the case details.

Anna noticed this, and reminded him "You know we generally don't put rooks on such high profile case?". Cas's shoulder fell. She continued," But maybe I can make an exception for my little brother". Even though Anna couldn't see his face, as his back was turned towards her, she was positive that his face had lit up.

Cas was actually grinning ear-to-ear. He really wanted to be a part of this hunt. He wanted to impress his siblings with his skills. He knew he was good and a natural. And he wanted to show them that. And this, of course, was the perfect occasion. And with his knowledge of behavioral analysis (the only one in the station to have that, he had checked), he was sure that he would be able to help a lot.

"But before that, you need to go on routine patrol with Officer McNally, who will also be your training officer. You think you can handle a 12 hour shift on your first day?", Anna said, while tapping on her hand-held.

Castiel's face fell at the prospect of having to drive around the city all day to break up petty squabbles and such. But obviously, his sister had rules to follow and he was going on a real case in the evening, so he just nodded. He then realized that her sister was looking at the computer rather than at him so he hastily added an "Yah, sure!", while thrusting his hand into the pockets of the light jacket he was wearing.

"Okay, good, then. Your uniform is in your locker and also your service revolver. And there will be some paperwork there too. Turn them in as soon as possible. And, uh, here's your key and your badge."

Castiel wordlessly took the small brass key and the badge. He lightly ran his fingers over where his name was written on the badge. A small sigh escaped his lips.

"So then, I'll see y'all later?", Cas was excited to put on his uniform.

"Actually, stay put, I wanted to give something to you", Anna said after looking at both his brothers briefly (who both nodded), and then started rifling through her drawers.

"Sure, what?", rocking on the balls of his feet slightly, noting the small exchange between his siblings and guessed it was probably some family-related matter.

"I wanted you to have Dad's old Glock", Anna finally said, pulling the aforementioned object into Castiel's view.

Cas stopped rocking and his vision snapped to the black gun. His eyes moistened a bit. And even though he opened his mouth to say something, nothing came out.

He felt a hand on his shoulder and looked back at his brother.

"Go on take it, he had told me in the hospital that he wanted you to have it if and when you joined the force."

Castiel immediately protested - " But Mike, that's Dad's and-and I can't just take it. You are older than me and you should have it."

"It's okay, we have talked and you can keep it. He would have wanted it." Michael's voice was firm and soft.

Castiel looked wordlessly at his other two siblings. They smiled encouragingly. He moved forward and picked up the gun, and gripped it tight.

"Oki doki, kiddo, now go change into your uniform and keep our city safe.", Gabe stated breaking the slight tension in the room.

"Yeah, I should get going."

"I'll tell McNally to meet you in an hour. Look around the station for a bit until your shift starts. Bye Cas."

Cas nodded then went out after a quick "See y'all later".

It was almost midnight and their shady Alonzo Mosley/Eddie Moscone/whatever-crappy-name-he-thought-of still hadn't arrived. And Cas was tired. His white shirt clung to him uncomfortably with sweat, and he hated that he had to wear a jacket. But it was necessary to conceal the gun that was resting snugly against his lower back.

Damned hot Miami weather.

He swore as he trudged through an alleyway in Downtown. If his profile of the guy as right then the guy would prefer places like this.

Places that were well lit. Places that drew less attention from gangs and cops alike so that he could do his job in peace. Plus, he apparently liked to show-off, always making a grand show. Be it going for overkill as he carved designs on the flesh of his victims or hacked their heads off after killing them just to show he could, or just plain terrorizing them. The guy was narcissistic and delusional, not to mention sadistic.

Hence, he had extended his shift (after much groveling from his end and a sincere 'Take care' from Anna) and was looking around. A lot of other cops were also in the area, keeping lookout. Mainly in the known hideouts of the local gangs. The location give by the informer was vague at best and the cops had to canvass a large area. He knew the guy wouldn't be stupid enough to show up there. However, he couldn't exactly establish this so he had sneaked off to do his own investigation. And maybe that was the worst mistake of his life.

Please leave a review. Constructive criticism is welcome!

That's all.
