I'm looking for a Castle fanfic that I read some time ago. It's a few years old, and I read it on www.fanfiction.net. Castle and Beckett are on a date and Castle disappears. He is taken by a man who turns out to be his father. His father is a CIA agent, I think, and has taken Castle to protect him. They hide out on an island for a while and return just in time to help Beckett take down the bad guy (I can't remember who this is, maybe Tyson?) If anyone can help me find this fic that would be great! Thanks!
