this be my favourite columbo . martin landau ( excellent . ) play twin and one of whom may have commit a murder . this columbo be unusual because the usual murder scene at the begin doesn not give you any clue to which one do it . peter falk be on form a usual in this episode write by steven bochco ( who also write murder by the book and my second favourite episode ) . the support cast be great especially julie newmar ( very under rat ) and jeanette nolan a the house keeper that columbo just keep on upset . the surname of martin landau character in this be paris . that be the surname of leonard nimoy character in mission impossible . coincidence . or a steven bochco joke .
