Burke's Law - Season 2 Episode 31 : Who Killed the Grand Piano? 1966

Pianist Artur Bachner's concert ends with a bang when his piano explodes, killing him. Anyone could have tampered with it during the backstage party before the concert - his abused ex-wife, a rival concert pianist, his personal manager, his horror movie star brother, or the woman he had been pursuing (now a ""Bunny Mother"" at a local Playboy-like club). Les, Tim and Sgt. Ames each have their own favorite suspect, but Burke's feisty Uncle Patrick, over from Ireland for a visit, helps solve the case (while getting cozy with Burke's date). The secret to solving the case is in the fact that the piece the victim was playing had been written so he was literally the only one in the world who could play it.
