the best columbo ever . the best villain ever . jack cassidy have log the most appearance of any columbo killer up to this point . he be to die in a horrible fire only a few month later . the suave and sophisticated cassidy and the down to earth falk play off each other magnificently . santini ( cassidy ) never sweat and never get nervous and never appear ruffle all throughout the episode . even at the end when columbo have him dead to right and show him the paper which contain the incriminate eveidence against him and santini say this one be burn . he then burn it into thin air . columbo say watch closely and sir . this be my best trick . he then pull out copy after copy of the document and hand one back to santini . you can burn this one too if you like sir and there plenty more where that come from . a classic end . the best columbo .
