Mike Royce, Becket's former police mentor, who lost his bounty-hunter license when she arrested him, is murdered while visiting New York, possibly by a fellow passenger from L.A. The captain takes her off the case but she uses extant leave. Castle comes along, having to visit his book's movie set anyway. Informally backed up by Ryan and Esposito, they soon find Royce must have been after the manufacturer of the dissolving type of bullet he was killed with. The trail of arms-dealings and new crimes leads back to New York, fortunately as LAPD detective Kyle Seeger, who follows, wants them out as much as Montgomery ordered Becket back. Written by

When Castle visits the set of "Heat Wave" in L.A., he and the film's director pass by a set of an airplane fuselage. This is the real Castle
(2009) set in which Nathan Fillion
and Stana Katic
shot the scenes of Castle and Beckett flying to California and back to New York. See more
After questioning Reggie, as Beckett takes off her disguise, she undoes her top button of her shirt. In the next shot her shirt is fully buttoned up. Later, it is shown undone again. See more
Yo, you were right about the silencer. The lab found trace amounts of titanium alloy in the threads. They've narrowed it down to one of two commercial suppressors. Both run about a grand.
Why put an expensive silencer on a cheap gun?
Because... our killer followed Royce from L.A. and couldn't bring his own gun on the plane.
But a silencer is just a cylinder. It could easily be hidden in a checked bag.
