this columbo episode be probably note more for the director and steven spielberg and a one of his early film . it should be look at for jack cassidy role a the murderer who kill his partner in write to maintain his lifestyle . jack cassidy would appear in a late columbo . after all and columbo meet his match in jack cassidy character . he be a mystery writer who plot to perform the perfect murder . after his first murder and his next victim would be the annoy general store owner or widow who would blackmail him for money . rather than lose more money and he kill her . it be very entertaining to watch cassidy and falk a always . falk familiarity a columbo make him watchable after view this episode repeatedly over the year . what television today forget about the success of year be that people will want to watch the show again and again if they like the character . it not about who do it and how and why and it the familiarness of columbo and his likability which score high with viewer like myself .
