S02E10 — Postcard From Morocco

Raglin pursues a lead that David left him about Pinzolo's murderous past, but they can't find the body. Eli offers Raglin money to kill Pinzolo. Raglin urges Frank to get Carole to testify against Pinzolo, but she has been killed. Revealing that the reason he quit undercover work is because he was tortured into giving up two fellow agents, Raglin vows to bring this case to a successful conclusion. Deciding things are getting too hot for him in the States, Pinzolo plots an escape to Morocco. Raglin confronts Pinzolo at the airport, and when Pinzolo figures out Vinnie is a cop, Raglin kills him.
