We start off the fourth season of Columbo with a discussion of Exercise in Fatality in which our titular detective squares off with tough guy and fitness guru Milo Janus (Robert Conrad) in a case that gets everyone tied up in knots. 

This episode also features an interview with Amelie Hastie, author of Columbo: Make Me a Perfect Murder, a close reading of the series.  Get it now at https://amzn.to/3xf8Pjk
