I appreciated all of "The Maltese Falcon" references, from McGraw's partner's name Archie Miles (Spade's partner was Miles Archer), the similar secretary, and the partner's names on the window, to Spade's/McGraw's quote "When a man's partner is killed, he's supposed to do something about it." Made it fun to watch, to catch any similarities! Otherwise, it was the standard "Murder She Wrote" episode, which isn't a bad thing. As I've been going back and watching all of the MSW episodes (for the third time), I've selectively been watching those with Harry McGraw, Michael Hagerty, and Dennis Stanton. This episode is one of my favorites!
