all i know about jack cassidy be his son who be in the hardy boy . he die before i get to know him . i think this be my favorite columbo episode with him a a magician with a secret and he be a nazi in germany during world war ii . cynthia sikes play his lovely daughter who be clueless about her father identity and history but she be memorable and she be well know for her role in st. elsewhere . sadly and i hat read about jack cassidy tragic death . wherever you be jack and we miss you still after 30 year . columbo always catch his man or woman even in this episode . a columbo always say and there be no such thing a a perfect murder . just when you think he get away with his crime and nothing could be far from the truth . if you love columbo and you will love this episode and how he catch his man be just as much fun to watch and learn .
