Richard Diamond, Private Detective is a radio crime series with Dick Powell in the title role, and the recordings here keep the sponsor's commercials in place. That turns the first stretch of each episode into a small period piece of its own. A Rexall family druggist comes on to speak for the independent druggists who carry the Rexall name and recommends one product at a time. Sometimes it is MI-31, sold as a mouthwash, gargle and breath deodorant that kills germs on contact. Other times it is Bismorex, an antacid, or a multivitamin capsule that promises liver concentrate and iron alongside the vitamins. The sign-off barely varies: good health to all from Rexall. Then comes the promise of another exciting half hour, and the register flips. Diamond's agency greeting is a joke that changes from one episode to the next. One version rhymes: 'when it's murder or less and you're caught in a mess, if you can't pay my fee, my advice is confess.' Another offers to swap a little corpse in your home for something useful, and a third sounds like a product slogan until it lands on strangling. The comedy is physical as well as verbal. In the excerpt from 'Ice Pick Murder', a man named Seymour apologises for knocking Diamond over, and Diamond, with a desk on his chest, insists he feels great and wonders who needs teeth. Clients arrive wanting to hire him, and when one asks, he replies, 'Well, bless your little heart.' An old acquaintance, Frank Bowers, gets back in touch and calls him Rick. Even the billing is played for laughs: in 'Mrs X Can't Find Her Husband', the introduction of a special guest star stalls because the guest will not give a name. The case titles lay out the beat, running from murder to a kidnapping to a fixed fight. Names sit right in those titles, among them Mary Bellman, Martha Campbell and Edna Wolfe. The draw is the contrast between grim subject matter and a lead who meets it with one-liners. For a first listen, 'The Fixed Fight Case' has the rhyming greeting, and 'Ice Pick Murder' has the desk mishap. Anyone curious about how radio advertising once sounded gets the Rexall reads as a bonus.
