The Good (S05E22)

After a suburban couple is found bludgeoned to death, Detectives Logan (Chris Noth) and Barek (Annabella Sciorra) suspect that their drug-troubled son Kevin (guest star Keith Nobbs) killed his parents' for their cash stash. But when a local investigator pressures the kid into a confession, the city cops discover a conflict of interest. While another suspect with close business ties to the victims emerges, Captain Deakins (Jamey Sheridan) urges Logan and Barek to drop the non-jurisdictional case – and ponders his own future with the NYPD.
