S19, E19: When a firefighter and his wife are found tortured and brutally murdered in their new townhome, Detectives Lupo (Jeremy Sisto) and Bernard (Anthony Anderson) struggle to find a motive. The couple’'s recent purchase of an expensive Art Deco lamp signals to Lieutenant Van Buren (S. Epatha Merkerson) that they were living beyond their means. The search for the killer leads detectives to an old, unsolved case involving drugs and missing money, as well as a tight knit group of firefighters with something to hide. Also stars Sam Waterston, Linus Roache and Alana De La Garza.
