Columbo has to match wits with Robert Culp again in this episode. I don't know offhand how many episodes that featured Robert Culp but I remember this one. He is a scientist who specializes in mental manipulation. I couldn't think of another way to explain it. Anyway, Columbo has met his match in this episode. Robert Culp's character kills somebody who wants to destroy his professional reputation as a top scientist who helps improves sales in grocery stores and other ways. Anyway, you have to watch how Columbo catches him. Like a typical episode, he becomes interested in his line of work but does not forget the victim or the crime. It's worth noting that it's pretty sophisticated in 1973 and I would watch it again if I have too but it's not my favorite episode of his or with Robert Culp.
