Our heroes try to solve some purr-fect crimes in these old time radio mysteries - each involving a cat. First, Sherlock Holmes and Dr. Watson (played by Tom Conway and Nigel Bruce) find "The Clue of the Hungry Cat" (originally aired on ABC on October 26, 1946). Next, Bob Bailey tries to help an inventor and finds a murder in "The Iron Cat" from Let George Do It (originally aired on Mutual on June 12, 1950). Then, a panther is on the loose in Los Angeles and Sgt. Joe Friday has to track it down in "The Big Cat" from Dragnet (originally aired on NBC on June 15, 1954).
