Love Me Dead

Plot:

Highly respected A.D.A. Jack Buckley, a tough crime-fighter, was murdered. His ex-brother-in-law Paul Cho, a businessman who likes call girls, was blackmailed by Danton to tell Buckley to back off. Castle and Beckett discover it's all about the discreet cyber-prostitution business, which happens to employ Buckley's legal protégée, Scarlett Price. Working out who took over the 'Danton' franchise when founder Dan Tonelli is jailed, leads to some surprising revelations. Meanwhile, 'cool dad' Castle worries about what secret Alexis shares only with Beckett.
