about thirty minute into the film and i think this be one of the weak columbo ever because it have the usual beginning ( a murder happening and then columbo come and inspect everything and interrogate the main suspect ) square . it be bore because i think i know everything already . but then there be a surprising twist that turn this episode into a most exciting one . suddenly and many character be involve and i start to guess with columbo and the end be just like agatha christie poirot ending be . the film be full of irony and and look back and i must admit that the whole episode be great work of the writer because the ordinary first part be a mere tool for create this irony and create a huge fool the audience scenario . don not turn your television off before the end .
