When investigating a case, Kate and Castle cross paths with the FBI's Fringe Division, but in the least expected way. Set on season one of both shows.

A chance meeting between two women with more in common than they could ever foresee, for Beckett and Dunham find they have a shared spirit for the job and in life. Professionally and personally, they recognise within each other the potential for both teamwork and friendship.

Kate finaly think she got the guy the shoot her mother, but did she really get him?

Just another normal day in the Castle / Fringe universe. That is until HE shows up... Disclaimer: I don't own Castle or Fringe

Olivia and Peter are tracking down William Bell and it's led them to New York City. Beckett is working a case that leads her down the same trail, as fate would have it, they meet at gun point. Will they be able to work together? Plot heavy with lots of Polivia and Caskett goodness. Also look for the development of Rick and Peter's bromance.

A collection of oneshots dabbling in possibilities of the Frastle multi-verse. Ratings may very. Events definitely will.

When their latest murder victim turns out to still be very much alive, Beckett and co. are in for a hell of a time. Especially when a division of the FBI they've never even heard of shows up to help.

Castle y Beckett se ven inmersos en un caso que no esperaban con un grupo del FBI que desconocían que existía, la División Fringe

Castle gets to see the real and raw Kate Beckett when he goes searching through her mind. Castle-centric under a Fringe concept the premise of 3x19 LSD . small cameos of Walter, Astrid, Peter, and Olivia at the end.
