This is NOT a Caskett story. There is major character death. Very permanent death.

One chapter only!

Kate knocked on Roy's open door and stepped just inside. "I'm told you wanted to see me, sir." Kate had no idea about what. She had put up with Castle. Had him arrested for a felony, only to let herself be talked out of pressing charges.

Not just the theft of Police property, but she had agreed not to press charges for sexual harassment. She had a case against him, but Roy had talked her out of them. It was against her better judgment, but she had agreed. Roy had promised to put his foot down and keep Castle under control.

"I got a call from the mayor's office. You have a fan." Roy liked it, though he was afraid of how Kate would take it.

"A fan, sir?" Kate didn't have a fan. Hell, she didn't even have a boyfriend. Not that under her present circumstances could she afford a boyfriend or keep one. That was out of the question.

"Richard Castle. It seems he's found the main character for his next novel. A tough but savvy female detective." Roy told her as he thought about her learning to love it.

"I'm flattered?" Kate said skeptically since that was all she could think of.

"Don't be," Roy said dryly. "The man says he needs to do research."

"OH, NO!" Suddenly Kate knew just who he meant.

"Oh, yes," Roy countered.

Kate fought back. "Sir, he's like a nine-year-old on a sugar rush. He's completely incapable of taking anything even remotely seriously."

"He did help solve this case," Roy pointed out. Kate scoffed at the thought. He was more jackass than helpful.

"When the mayor's happy, the commissioner's happy. And when the commissioner's happy, I'm happy." Roy smiled at her since he was happy.

Kate fought back. "And when he gets himself killed, will you still be happy? What happens when he gets me killed, or Javi, Kevin, or anyone else killed? Will you, the mayor, and the commissioner still be happy? Because it will happen. A child like Castle is going to get someone killed. He won't listen, sir. He'll do the exact opposite of what anyone tells him to do."

"Those are your orders, Beckett." Roy knew this wouldn't go over well, but Beckett needed to loosen up and Castle might be just the person to do it.

"How long?" Kate would find another way to get rid of him.

"That's up to him." Roy nodded toward his doorway, where Kate saw a victorious, smirking Castle waiting for her.

Kate huffed, left his office, and pushed the writer out of her way. "Out of my way, Castle." She stomped her way to her desk and sat down.

The next thing Kate knew, Castle was sitting in the chair next to her desk. "I promise to listen," Rick told her.

"And you're lying already," Kate snapped.

"What makes you think that? And that's rude, by the way." Rick did plan to listen to her. Though if he didn't like what she said, he would ignore her.

"Because you're a child, Castle. Children lie all the time. They have no concept of what their word means, and neither do you. If they ignore the consequences of their lie long enough, it'll just go away.

"So why don't you just beat the rush and go away now, before you get yourself or one of us killed? These are real killers with real guns and real bullets. Your pen isn't mightier than my gun. Your pen will get my blouse dirty while my gun will kill you," Kate fought back for the second time that morning.

"You don't have to be mean, Beckett." Rick didn't like how this was starting, but he would win her over. No woman could resist him. She would change her tune eventually. In the meantime, he had to get inspiration from her for his new book.

"Castle, I went to the Police Academy so I could qualify for this job. I spent my time in a patrol car and paid my dues. I spent time in Vice before making it to Detective. I'm qualified for this job. You. Are. Not.

"If I thought all I had to do was spread my legs for the mayor to get this job, I might have considered it, but I didn't. I did it the hard way," Kate told him.

"That was mean, Beckett. But that was so cool! I need to write that down." Rick pulled out a small note pad and a pen and proceeded to write, causing Kate to moan and scrubbed her face with her hand.

She should have known better than to try and reach a child. Even insulting him by suggesting that he had spread his legs to the mayor hadn't worked. It left her thinking he couldn't be insulted. He had to care what people thought of him first.

She should have known better than to try and reach a child. Even insulting him by suggesting that he had spread his legs to the mayor hadn't worked. It left her thinking he couldn't be offended. He had to care what people thought of him first.

"I have work to do." Kate took her weapon out of her desk drawer and got all of two steps away from him.

"Ooo, a dead body!?" Rick was excited.

Kate lied to him, thinking it would keep him right where he was. "No, real work. The kind of work you don't do."

"Paperwork!" Rick shuddered in disgust and stayed where he was. At least until he got bored and Beckett wasn't back yet, so he went over to bug Javi and Kevin. His charm should work on them too. It simply worked on women better.

x-{Z}-x

The detective was thankful that it wasn't a school day. Kate didn't have to do this, she knew she didn't. She honestly didn't want to kill Castle, and what she was thinking of doing to him was going to kill him, but not actually kill him completely.

Still, her mother was dead, and she knew that kind of pain. Her father was all she had, so Kate was willing to give her a chance to keep her father before she got rid of him forever.

Kate watched the door open. "Detective Beckett?" Alexis was a little shocked. "If you're here to arrest him again, I'm sorry, but my dad's not home." The teenager knew Beckett had cause to arrest him and was thankful that her dad wasn't still in jail awaiting trial before being sentenced to prison.

"Yes, I know. Your father's back at the Precinct. I'm here for you." Kate meant talk to her. She was only fifteen years old, and that was too young for her to be here for her. Castle, however, was more than old enough. Physically, anyway.

Maybe when Alexis was eighteen years old, she would revisit the idea, but for now, she was safe.

"Oh? Okay, come in, please." Alexis stepped back and let her in.

Kate had never been there before, and that told her what money she didn't have could buy. It was breathtaking and was filled with beautiful furniture. It must be heavenly to live here.

"What can I help you with, Detective?" Alexis inquired as she made her way to the kitchen. She had a guest. "Can I get you something? We have just about everything, including ones I choose not to drink." She meant alcohol.

"Nothing, thank you. I'm good." Kate could drink and eat a little, but she didn't require food or drink. She could even drink anyone under the table since alcohol of any kind didn't affect her at all.

Alexis took out a can of Diet Coke and poured it into a glass of ice. "So, what can I help you with?" She turned her attention to the Detective.

"Your father. We need to talk about Castle," Kate informed her.

Alexis sighed. "What has he done now?" She should have known her dad was involved with Beckett being here, so it wasn't that big of a surprise.

Kate raised an eyebrow at that comment. Obviously, Alexis was used to her father doing stupid stuff like this.

"Castle has managed to attach himself to my team. He got the mayor to call the commissioner, who called my captain. And now I'm expected to drag Castle around with me everywhere I go. When I go to bring in a suspect, he goes with me. Go to a body site, and he goes with me. Everywhere I go, he goes," Kate explained.

"I don't see how I can help you, Detective." She was his daughter. She didn't have control over the mayor or the commissioner.

"I'm hoping you can reach him. You know what happened on the last case. If not for Captain Montgomery talking me out of various charges, he would either still be in jail or out on bail awaiting trial for felony charges.

"Castle didn't even see the hazards of what he did. He doesn't see the hazards that he's going to get into this time either," Kate began to tell her.

"Such as?" Alexis still didn't see how she should be involved.

"In my world I hunt down murderers. Most, if not all, have no intention to pay for their crime. If that means killing me and my partners like Javi or Kevin, they will do so.

"Not all will be carrying a weapon, but it will happen. Castle refuses to listen. Tell him to stay in the car where he's safe, and he says okay. But two seconds later, he's not in it any longer. I'm sorry, but there's no way I can trust him.

"So, in addition to protecting myself from a potential killer while supporting and protecting my team, I'm now expected to keep an unarmed civilian from harm, someone that has no business even being there.

"I want you to talk him out of his idea. I lost my mother, and I know that pain. I'm extensively trained, Alexis, and this is my job. I don't sit behind a desk writing fiction. I live in reality. I'm not saying it will happen, but since he has no training, his chances of being hurt or killed are seriously high.

"I'm asking you to try and save your father before it's too late. The pain of losing a parent is something I know well, and I'm asking for your help to prevent it.

"I went to the Police Academy, paid my dues in a patrol car before moving to Vice, and finally made it to Detective. People kill people, Alexis," Kate said. "If your father's in the wrong place at the wrong time, he could be next."

"I see." Now Alexis understood why she was here. "I'm not sure he'll listen to me. I can't get him to stop being a playboy or signing women's chests. If anything, he wants me to be more like him. Create memories I will regret later in life making.

"Dad listens to Gina and himself, but not so much me. Is the danger really that great?" Alexis asked her.

"It can be, but there are no guarantees. Suppose I have to choose between saving Castle's life or Javi's, Kevin's, or another officer's. Who do I choose? Shooting a paper target is simple if you've trained for it. But actually ending a life to save your own or someone else's is another matter entirely. It changes you. Not that Castle's allowed to carry a weapon, but what if he gets his hands on one?

"I work in real life. Castle works in fiction, sitting at his desk. I'm asking you to help me keep your father alive and safe. If he at least had training, I might not be here, but he's an unarmed civilian. So I'm asking for your help."

Alexis stood there in the kitchen and thought about it. She knew what her chances were, and they weren't good. "I can try, Detective, but as I said, Dad doesn't really listen to me much."

"That's all I'm asking, Alexis," Kate asserted. "Perhaps I'm overreacting, and nothing will happen to him, but this isn't that safest of cities." And she wasn't going to put up with him following her around. She had secrets that she needed to keep. If she allowed Castle to follow her around, he might somehow find out what her biggest secret was, and she couldn't have that. No matter the cost to him, or Alexis, or his mother.

"I've said my peace. I wish you luck, Alexis. I'll let myself out. You can lock the door after I'm gone." Kate let herself out and went back to the Precinct.

No sooner than she sat down at her desk when suddenly Castle was there, and he wouldn't shut up.

"Is there a point to all this babbling, Castle? Does it solve any of our open cases? Have you ever decided to read any of our open cases? Or are you just here to make sure my life is miserable," Kate demanded.

"Are you always this mean? And to answer your question, I didn't know you had any open cases," Rick said.

"I don't want you here, Castle, and I certainly didn't ask for you to be here. In fact, if Captain Montgomery hadn't talked me out of pressing charges like I wanted, you would be awaiting trial on federal charges.

"And if you offer to debrief each other again, I won't drop the charges. Captain Montgomery won't talk me out of it again. You may act like a child, but you'll be tried as an adult and spend the next twenty years in federal prison," Kate informed him, her eyes blazing with anger. "You can write your blasted books from prison."

"Got it." He didn't like it, but he got it. Still, it was good stuff for Nikki Heat. And with that, he pulled out his little notepad and pen and began scribbling.

x-{Z}-x

Kate was home and finally free of Castle. Stripping till she was naked, she stepped into her bathroom to wash up a little, and to take off what little makeup she had applied this morning.

Going over to her dresser, she took out a new pair of panties, shorts, and a t-shirt. She wasn't expecting company, and even if Lanie did suddenly show up – and she might if Javi had blabbed to her that Castle was now attached to her – she didn't care if Lanie saw her nipples poking out her t-shirt.

Since she didn't need food or drink, she tried to decide whether to read a new book that sounded interesting, watch a new DVD movie, or find something on TV. There were a few things on TV worth watching. Maybe even a baseball game. Likely not the Yankees, but any baseball would do.

Kate stopped on Pittsburgh Pirates playing Chicago Cubs. She didn't care who won. She was just interested in seeing what moves each coach made during the game.

Who was pitching, and were either any good or were the teams that bad at batting? She even wondered just how far she could hit a ball. Just not as a human. Humans, even her, had certain restrictions, and strength was one of them.

It was a little interesting, but then there was someone at her door. They weren't even knocking on her door. Whoever it was, they were pounding on it! Since Lanie had no reason to be that mad, she had no idea who it was.

Flipping the lock and opening the door, she saw who it was. "Castle?" What the fuck was he doing here? Even more to the point, how did he find out where she lived? She definitely hadn't told him, and the NYPD would never give out that information.

Castle pushed past her and walked right into her apartment. Talk about rude! "What do you want, Castle?" Couldn't he just leave her alone? Let her live her life without him like she wanted to do?

"You came to my home and talked to Alexis. What gave you the right to talk to my daughter?" Rick was beyond furious.

Kate raised her chin. She was over and done with trying to be polite. "Yes, I talked to her. You've inserted yourself into my life where I don't want you, so I talked to Alexis. What we do isn't a game, Castle. I'm not risking anyone's life because of you."

"You leave Alexis out of this, completely out of this," Rick growled. "I'm following you because I have an idea for a new character. I'm going to follow you around so I can get her right. I have the mayor's, the commissioner's, and your captain's approval," he reminded her.

"Fine, Castle, I've had enough of you. You asked for this, so you're going to get it. Alexis will just have to find a way to survive," Kate threatened and reached to pull her t-shirt over her head, exposing her breasts to him.

Then she pulled her shorts and panties down simultaneously and stood there as a naked human for a moment.

Rick was shocked by that. Sure, he was interested in taking her to bed and making her one of his conquests, just like he had offered at the end of the last case. So, Rick was looking her over. He knew she didn't have the size of tits he loved, but she was still lovely.

Abruptly everything changed or began to change. Beckett's tits got bigger and bigger. Then he noticed wings coming out from behind her, and there was this tail whipping around.

Little horns came out of her forehead, incredibly her hair grew a lot longer and went from brown to jet black, and her skin color changed.

Her body was more reddish now, just like her wings and tail. Rick had never seen anything like that before. But his memory suddenly reminded him of something he had read long ago. He had even seen a few illustrations of one.

Her body began to produce pheromones of a far greater potency and concentration than ordinary humans' were. Hers was capable of creating an overwhelming level of sexual arousal in her victims. At the same time, her puffy labia swelled outward, revealing the wet pink flesh inside as her vagina began producing copious amounts of lubricant, causing the fluid to start to trickle down one leg.

She smiled as she waited; it was apparent that her pheromones were beginning to affect him when his skin became flushed and his breathing quickened. He was also having a great deal of difficulty maintaining eye contact with her. His eyes kept straying downward to her pert breasts and then farther down to her swollen mons. Against his will, he was rapidly becoming aroused by her presence.

In her green eyes, specks of gold glimmered and danced. Rick felt something like a moment of vertigo before his jaw slackened, allowing her tongue to explore his mouth in a kiss. As he continued to stare into her hypnotic gaze, a burning desire began to throb in his body and mind. Rational thought faded while his cock became rock-hard in his pants.

Her eyes gleamed with delight as she sensed his resistance break, replaced by need instead. She guided his hand between her legs, allowing him to feel her excitement while her own hands went to work rubbing and caressing his hardness through his trousers. They moaned into each other's mouths as their tongues sparred. Nimble female hands unfastened his belt and quickly undid his pants, freeing his erection before pumping and caressing it as they smeared pre-cum along his length.

Kate forced Castle to the floor, taking him by surprise. Both partners moaned in pleasure while she worked herself against his cock. Finally, Kate drew back, angled her hips, the head of his penis nudged into her entrance, and she grimaced in pleasure as she slowly pushed downward, little by little impaling her tight vagina on his stiff cock until she buried to the root.

She smiled and closed her eyes, laying her head against his chest as she grew accustomed to the feeling of penetration, experimentally clenching her inner muscles to squeeze the member that filled her cunt. Slowly, she began moving, rising up and down as she felt his shaft rub against her inner flesh. Moving faster and faster, Kate cried out and panted as she pounded herself down on him.

Kate squeezed and rippled her inner muscles, milking his cock while she let out little shrieks of ecstasy and bit her lower lip with pleasure. Her response to his thrusts only aroused Castle even more, and she moaned in anticipation as she felt him double his efforts, hammering into her body as he strove toward his peak. Like an animal, he impaled her again and again, stroking hard and fast as he fucked her. He gave a hoarse cry and finally came with an orgasm unlike he had ever experienced.

An expression of confusion appeared on Castle's face as his body continued to thrust into Kate outside of his conscious control. He couldn't stop coming inside her clenching depths as his climax went on and on without release. A tortured cry of intermingled pain and pleasure was wrenched from his throat as his cock jumped and pulsed, spurting his seed deep into her womb.

Kate laughed evilly, feeling his life force flow into her body, strengthening her and bringing with it a buzzing ecstasy which coursed through her core with an intensity far more intense than mere sex. The Succubus watched with a wicked smile as the life drained from his eyes.

Kate smiled victoriously. She slowly ground herself against his still erect cock with a hand pressed against her flat belly, reveling in the afterglow and the satisfaction of feeding upon his life's energy. Finally, with a sigh of regret, Kate rose to her feet. As she did so, her victim's cock slid from her vagina with a wet sucking noise.

Looking down at Castle, it was obvious that his body was worse for wear. His skin had turned gray, and he seemed seriously shrunken to half his size. Every vein in Castle's body was now black.

Pulling on a pair of latex gloves, Kate only had to find a trash bag after taking off all his clothes; she kept his wallet and phone for a moment. With the dead body in a trash bag, she took off the back of his phone and removed the battery, effectively killing it. Still, she went looking for her little pin, forced out the SIM card, and cut it into two pieces. Then she took the two thousand in cash and put it in her safe. Kate cut up Castle's credit cards and everything else in his wallet.

The body in a trash bag went into the trash bin behind the building. Castle's clothes, phone, and everything else went into a different trash bag. That bag would be dropped off in a different trash bin on the way into work the next day.

She had tried to save Alexis the pain of losing her father. She truly had. Still, she didn't need another man's life force for a while now. Castle's would keep her satisfied for some time.

x-{Z}-x

Roy came over to her desk. "Have you seen Castle, Beckett?"

"No sir, not since yesterday here in the office. I saw Alexis at their loft yesterday to try and get her to talk Castle out of following me around. It was a bad idea, sir," Kate told him.

"Alexis just called, asking if I had seen him. She knows he came home last night, but she doesn't know where he is now and he isn't answering his cell phone," Roy told her.

"I don't know what to tell you, sir. Have you gotten permission from her to have his phone pinged? Right now, he's a missing person, not a homicide," Kate pointed out.

x-{Z}-x

Without a body, Castle never became a homicide for any detective to track down. Rarely were missing persons found. And for the most part, Kate never heard the word Castle ever used again.

She had no interest in finding out how Alexis was getting along with a missing father. She had no idea when Castle was finally declared deceased or when his daughter and Martha finally settled his estate.

Kate had fed several times since then. It was something she would for the rest of her life. Depending on how long it took her to find out who killed her mother, Beckett would remain in New York City before moving to a different city in another state with a new ID. She could live for centuries so long as she got the male life force she needed. She would look and live at this age for centuries.

Kate had tried to save Alexis from the pain of losing her father, she genuinely had. But she was a Succubus, and her life came first above all others. At least she did decide to leave Alexis alone and not convert her into a Succubus just like her.
