Unrequited

"So what have we got?" Beckett asked walking down one of the city's many dark alleys. Castle, Ryan and Esposito were already there, Castle having just arrived and was sipping his coffee. Though she noticed there wasn't a second in his hand

"A young white woman, cause of death was a bullet to the back of the head," Lanie muttered sounding puzzled as she inspected the scene.

"She's wearing a diamond bracelet," Kate muttered kneeling down to inspect the body. Indeed the woman was wearing a lot of fancy jewellery

"This is pretty high end stuff, what was she doing in a neighbourhood like this?" Castle wondered aloud.

"This is gang territory, could be a robbery gone attack," Esposito suggested looking around,

"Then why leave the diamonds?" Ryan questioned.

"Do we know what she was doing here?" Beckett asked looking around, she couldn't see much around. One back entrance to a closed restaurant and a graffiti covered wall signifying nothing more than a dead end.

"No, but she wasn't killed here, there's no blood splatter. She was dragged here," Lanie interrupted standing up,

"The killer must have driven, you don't drag a body through a street without someone noticing," Castle interjected suddenly.

"I'll canvass the area; maybe someone saw something out of the ordinary," Ryan announced turning his back on the scene.

"Ok, Espo see if any of the cameras around here caught anything," Beckett instructed suddenly.

"Cameras around here not being smashed of fake? That's one of those things that can just never happen," Esposito replied in a warning tone, his eyes then caught Lanie's.

"Well you never know I suppose, sometimes you can be surprised," he corrected but found himself receiving an even more infuriated glare as Beckett and Castle looked oblivious.

"I'll look at the cameras, it can't be that unlikely," he said loudly before quickly scuttling away.

"What was that about?" Kate asked looking at Lanie whose eyes quickly darted towards Rick.

"I have no idea," she replied mystically.

"Anything to do with your date?" Rick asked suddenly remembering the doctor and the detective had gone out last night. They had waited for reservations for quite a while.

"No, nothing to do with our date," Lanie answered quickly.

Later

"So we have an unknown victim, an unknown killer, unknown murder weapon and an unknown location for murder. I'm going to guess invisible killer," Castle decided looking at the mostly empty board in front of him.

"Really that's it? No UFO? Time travel? Or any of the usual stuff?" Ryan wondered sounding almost amazed, Castle nodded.

"Point taken invisible CIA hitman," was his next try.

"There's the Castle we know and love," Beckett smiled, having been ignoring the man for quite some time.

"Who loves Castle?" Esposito asked suddenly interjecting himself in the conversation

"Everyone," Rick answered with a smile; usually the word love would have had him feeling like he had been run over but for some reason he felt ok. Esposito however looked a mixture of worried and relieved.

"Is that Charlotte Ollisan?" a suddenly stern and alert voice sent shockwaves through the air as Gates approached. Walking with narrowed eyes and a fierce stare which was transfixed on the victim's image on the murder board, looking a mixture of shocked and furious.

"You know this woman sir?" Castle asked, both of them agreed they would stay professional, they could be friends but she did not want anyone being casual in addressing her or any superior.

"Yes I do, Charlotte Ollisan, wife of Paul Ollisan," she muttered with a slight growl.

"Wait you mean officer Ollisan as in the officer Ollisan?" Castle inquired, all eyes were on him.

"Yes I do Mr Castle," Gates muttered.

"And just who is officer Ollisan?" Esposito asked, feeling out of the loop all of a sudden as everyone wondered how Castle knew who this officer was.

"He's an officer, a captain now who has a long and difficult history, I knew him a long time ago," Gates muttered in a voice that sounded ready to kill.

"What do you mean long and difficult, sir," Beckett questioned with a slight glance at Castle,

"A number of charges were brought against him over the years, none of them stuck. Domestic abuse, harassment and assaulting an officer, all of them dropped for reasons which have escaped us all." She replied with a growl.

"We'll look into him sir," Kate assured the evidently angry woman in front of her who seemed unpredictable all of a sudden.

"Do," she muttered before turning on her heel and storming back towards her office. The moment she was gone all eyes were on Castle

"How the hell did you know about any of that?" Beckett demanded, Rick paused; trying to think of an answer.

"He's a friend of a friend I met once, I knew he didn't have a good record but didn't know he was married," he explained, his eyes darting towards the captains' office. Kate Beckett didn't look overly convinced.

"We can take a shot at him in the morning, it's late," Ryan decided before she could say anything and with a quick nod it was agreed.

Outside

Captain Gates was going home early, normally she would work till late and recently she had been doing it to the extreme. After everything had happened with her husband she wanted to keep her mind as far away from it as she could. Though this new case was providing an unwelcome distraction,

"Need a lift?" Castle's voiced appeared from nowhere as he pulled over, it was cloudy and sooner or later it was going to rain. Once Gates would have said no and once Castle wouldn't have had the courage to pull over

"Thanks Rick," she smiled getting into the passenger seat.

"So how are you holding up?" he asked the moment they had set off, sounding worried.

"Fine," she answered quickly, she had no wish to think about it let alone talk about it.

"No I'm not," she sighed in the same moment. No she couldn't pretend, she was fine with breaking bad news, fine with tough decisions, hell she hadn't broken down in public after her husband but this she couldn't act through.

"You think he did it?" Rick asked and she appreciated him getting straight to the matter.

"When I first joined the force Paul Ollisan knocked my partner into the hospital for a week, he has friends and they pulled strings. He walked free, my partner walked out. That man pushed me to work for internal affairs. I hate that son of a bitch with every fibre of my being so yes Rick I do think he did it." Gates sighed sinking back in the car seat looking under pressure.

"We'll get him if he did it you know," Castle assured her and she smirked darkly.

"He's escaped justice every time," she corrected.

"Luck runs out," he countered as he pulled up outside her house. Her face fell.

"Who's that?" Rick asked seeing a foreign car and a strange woman outside the home.

"My husband and mother in law," Gates growled in a murderous tone "Obviously picking up whatever he left,"

"Well to stop a potential double murder I have a guest bedroom if you want to avoid them," Rick offered, it was late and judging from Gates' tone she was not going to enjoy their company.

"Anything but them,"
