Riley Greenleaf is a top publisher, however his most successful writer Alan Mallory is moving to a rival publisher. Greenleaf decides this is unacceptable and hires Eddie to shoot him, which he duly does.
Eddie only agreed to kill Alan under the condition Greenleaf published his book on explosives. Greenleaf obviously has no intention of doing this so injects poison into Eddie’s celebratory champagne and then, just to make sure, blows up his apartment.
Columbo appears at 14 minutes and 45 seconds. Interestingly (for me) Columbo references the events of Candidate for Crime. Less interestingly (but still interesting) Greenleaf appears to have his own private pornographic cinema.
The columboid involves changing locks.
Things we learn about Columbo: his wife made him stay up until 2am watching a Bette Davis film, his wife has a cousin in the Valley who owns a body shop.
During this episode I doubted the practicality of my outfit.
