What happens when Gates finds out about Beckett and Castle's relationship? How does Castle prove his worth to the Captain? Will he be able to stay at the 12th Precinct or will the partnership be broken? Starting sometime in mid Season 5 - pretty much fully AU from then on.

Has a gang of vigilantes been operating on the streets of NYC with Police protection for over a year without being detected? Castle thinks so. How do you solve a case when you have no suspects or evidence? Get them to confess of course!

This was a prompt from mysafewordisapples. Castle is murdered and comes back as a dog, but has 2 weeks to help Kate find his murderer. If he does he comes back as a human. If not he remains a dog. Tell me what you think. This is one big chapter! So yes, there is Character Death. Just how permanent, you get to read to find out. - COMPLETE

Kate stared at the murder board, her eyes bloodshot and her vision blurry but she couldn't rest. Not with the smiling picture of her own husband staring back at her. AU, Future fic.

There were so many things he wanted to say to her but that wasn't a part of their relationship. So he wrote her letters instead, hid them away, never intending for her to read them. Until one day, Kate stumbled upon them by mistake. Complete.
