The Wolves of Deep Brooklyn

S1, E12: Greed is definitely not good when Henry and Jo investigate the murder of a young financial investment star who came from humble beginnings and turns up dead near the East River. Coincidently, the victim also happens to be the son of one of Abe's wartime Army buddies. Henry's first case back on the job after a leave to recover from killing a man has Jo and Lt. Reese keeping him under observation out of an abundance of concern. Meanwhile, unbeknownst to Henry, Abe decides to play detective with his Army buddies to solve the murder, with surprising results. In a touching flashback, Henry recalls his anxiety over letting a 17-year-old Abe go to Vietnam after he is recruited by the Army. Guest star William Baldwin (Dirty Sexy Money, Gossip Girl) appears as Oliver Clarion. Guest star Clarke Peters (Treme, The Wire, Person of Interest) appears as Jerry Charters.
