Stand By For Crime - This show, from the early 1950s, is a good example of the true story style of delivery made popular in radio's classic crime shows Gangbusters and Mr. District Attorney.

 
CANDY MATSON was the private eye star of Candy Matson, YUkon 2-8208, an NBC West Coast show which first aired in March 1949 and was created by Monty Masters. He cast his wife, Natalie Parks, in the title role of this sassy, sexy PI. Her understated love interest, Lt. Ray Mallard, was played by Henry Leff while her assistant and best pal, aptly named Rembrandt Watson, was the voice of Jack Thomas.
 
Richard Diamond, Private Detective came to NBC in 1949. Diamond was a slick, sophisticated detective, with a sharp tongue for folks who needed it. Diamond enjoyed the detective life, but not as much as entertaining his girl, Helen Asher. After each show, he would croon a number to his Park Avenue sweetheart. Mr. Powell, a former song and dance man, was perfect for the role. He added an extra dimension to the 40's hokey private eye drama.
