Connelly, Patterson and Cannell return to CASTLE (and we have the clips to prove it!)

Mystery legend Michael Connelly, cottage industry James Patterson and uber-producer turned author Stephan Cannell all return to play poker with Rick on CASTLE’s season finale.

Here are a couple of promos, the first of which has Rickie and the boys playing poker. The finale, entitled A Deadly Game, airs on May 17th on ABC.
