AU. Meet Richard Castle, playboy mystery writer and reality television latest star. Beckett's undercover to bust a drug ring and part of her cover involves getting very close to one of New York's most eligible bachelors. The strait-laced cop isn't charmed by his flirty banter and she won't chase after him like the female contestants on the show. She's out to cuff him, not jump him.

AU. An alternative Castle/Beckett meeting. What if Beckett had been the arresting officer in that incident with the police horse. "Richard Castle you are under arrest for theft of a police horse and public nudity." Beckett glared up at the naked man sitting atop her horse.

A/U It's definitely not love at first sight. Prickly, aloof and strait-laced Kate Beckett isn't what Rick expected when he hires someone to protect a young Alexis. She's all business while he's all about the play. Shallow, irresponsible and a playboy is how Beckett would characterize her latest employer. But sometimes first impressions can turn out to be wrong.

The M version of chapter 17 of my story Bullet Catcher

What happens when your romantic plans get wiped out at the last moment? Castle is hoping to make their first Valentine's together something special but fate is conspiring against him. So he improvises. Drums, an elephant and a loin cloth, you can't get more romantic than that. No spoilers for the episode.

"You want me to wear this?" Beckett holds up a red lace merry widow trimmed in faux white fur. "I'm not sure that you've been good enough to deserve it." Kate and Rick exchange early Christmas presents.

Set early S4. Kate survives the bullet but their partnership doesn't. Almost everybody agrees that it's too dangerous for Rick to keep shadowing her, so she kicks him out for his own good. The only problem is that Kate can't seem to go cold turkey.

Mild spoilers. Based on the episode promo for "Murder He wrote". It's the pool scene minus the interruption of a dead body. "You forgot your suit." "I know." A cute giggle escapes her. "I hope you don't mind," she taunts him as she takes a few provocative steps closer. Her thumb brushes over the corner of his lips as she tells him, "Castle, you're drooling."

AU, three years on. Kate is married to a wonderful man, she has a job that she's great at and they're starting a family. She should be happy, right? Sometimes it isn't falling in love but staying there that's the hard part.

Castle and Beckett are masters of miscommunication. So many lost opportunities that make you want to slap them sometimes. Here's a story of how they get together but for all the wrong reasons.

We all know that Castle likes to play the clown and this time he tries to pull off the ultimate practical joke on Beckett, aided by Esposito and Ryan.

Something happens to make Beckett reevaluate her relationship with Josh. Castle tries to do the right thing despite his own feelings.
