Diamond Detective Agency. A pleasant smile, a cheerful rhyme, and we'll keep you from doing time. A quip, a carefree whistle, and a case closed - that's Dick Powell's Richard Diamond. Clients can be scarce, but he's not a bit worried. You see, he's "in partnership with a shill called human nature." And she's really quite reliable. Sooner or later someone will need his services for matters of protection or pay back, blackmail or bombs, modern art or murder.
