A soprano's daughter is killed during a rehearsal break; she plays the violin and "maestro" gonna make her soon the first violin in the orchestra. Anyway there's something hidden behind scene and it takes time to Logan and Barek to figure out. The singer (Alice Krige) has a lot of medical issue due to a disease inherited from his father and she has to find the right person who could take care of her situation that already starts to degenerate (she forgets things, falls down while running and she's unable to find her way out). Her only child doesn't seem too supportive, she just wants to pursue her career, so mother's choice fall upon another person. Is he willing to do that?
Medical examiner (who stated having a date with Lennie Briscoe) performs some verses of "Rigoletto" much to Logan disapproval. I discovered in this episode a new way in smuggling drugs by soaking stage costumes.
