Unholy Alliance - S1.E3

Sam investigates a series of murders which bear striking similarities to the methods of a killer (Benjamin Mouton) whom Bailey put in prison 10 years earlier. Sam suspects that the real culprit is still free, and through her gifted insight, she finds clues in the ancient I Ching art of divination that lead her to a high-ranking military officer (Carmen Argenziano), who may be protecting the slayer (Ian Patrick Williams).
