Most of this episode takes place in a prestigious San Francisco music conservatory, where a highly unpopular violin instructor has been murdered. Investigating the case, Ironside (Raymond Burr) discovers that there is no lack of suspects. Zeroing in on a trio of decidedly eccentric musicians (one of them played by a young Tim Matheson), the Chief tries to determine the killer's identity by following some cryptic clues left behind in the victim's collection of classical compositions. ~ Hal Erickson, Rovi
