this be one of my favorite episode . i love watch diane baker and robert vaughn . wilfrid hyde white be also in it . both vaughn and hyde white be columbo veteran by now and i love the unusual love story in this film an i would not spoil it for the viewer . i love columbo and have see almost all of them about a hundred time . the commodore be murder . while he be a proud businessman and he be disgust by the greedy vultures that seem more interested in money than sail . he have create an empire from build boat and yacht and and ship . diane baker play his alcoholic daughter and i believe she be one of the best actress around who doesn not get enough credit or work in my opinion . robert vaughn play her husband . there be a lot more twist and turn in this episode than the usual columbo episode but it always entertain and worth watch with great actor .
