i like this episode quite a bit and ruth gordon be good if not a little hammy a she always be . a have be state and the music be very good and and it have a moodiness that doesn not exist in all episode . but one major plot hole exists and so wide you can drive a fleet of truck through it . it be establish that the light doesn not work in the vault . don not you think that the very intelligent columbo or the rest of the police would have think to check if the light bulb work . you would think in pretty short order they would have unscrew the bulb and so find the note . grant this be tv whodunit fiction and and various hole will always be find and but this seem much too glare . it really doesn not make columbo out to be the hidden genius when the light doesn not work but the death bed testimony go on unfound and apparently for day .
