The Richard Diamonds now in circulation are a must for the detective show freaks in the OTR audience. Dick Powell, the flip lady-killer crooner, is perfect as the flip lady-killer crooner detective. With more humor than Howard Duff's Sam Spade, with more unbelievable scripts than I Love a Mystery, with more dazzling chicks than Mike Shayne, the Richard Diamond series must be rated No. 1. On most shows, Powell answers the phone with his newest slogan for his business, like "Diamond speaking, a girl's best friend," or "Diamond's tough when he's in the rough."
The shows are far out too. Take "The Gray Man" (02/16/1951), who has been poisoned and is gradually turning colors, or the "Blue Serge Suite" case where every blue serge suite in town is disappearing! Or the time Rick takes a job in a butcher shop where "The Stakes Are High."
Helen is the perfect girlfriend. Unlike most detective's girls, she stays out of every case. You know Margo Lane had to be snooping over Lamont's shoulder. And Ann Williams, Casey's sidekick in crime photography, had to be taking every other picture. Edith Miller in Mr. DA even helped to solve crimes for goodness sakes! But not Helen. She waits in her rich, stately penthouse for Rick to finish his case, and when he finally shows up, he croons the Camel commercial, the kiss and fade out ... Diamond, you're a chauvinist pig but I love ya!
Here are the Diamond cases that I have heard. Maybe there are others you know of to add to the list.
