Jazz pianist Johnny Staccato supplements his meager musician's income by working as a private detective. The backdrop for many of the episodes is his friend "Waldo's" jazz club in New York City's Greenwich Village, featuring performances by the Pete Candoli jazz combo, which included Barney Kessel, Shelly Manne, Red Mitchell, Red Norvo, and Johnny Williams. The theme was composed by Elmer Bernstein.
