In this bonus episode, I'm sharing my five favorite installments of Barrie Craig, Confidential Investigator. William Gargan sleuths with a sardonic smile in these radio mysteries, beginning with "The Lost Lady" (originally aired on NBC on June 14, 1953). A client behind bars hires Craig in "For Love of Murder" (originally aired on NBC on August 3, 1954), and Craig helps an old colleague close one last case in "Blood Money" (originally aired on NBC on August 24, 1954). A vacation is a new setting for murder in "Hay is for Homicide" (originally aired on NBC on August 31, 1954), and a visit to see a friend turns into a night at a haunted house in "Ghosts Don't Die in Bed" (originally aired on NBC on September 7, 1954).

Place your bets and ride along with four old time radio mysteries set in the stables and around the racetrack. Boston Blackie doubts a horse is guilty of murder in a syndicated mystery, and international investigator Frank Race tries to find out who's out to make sure a prize racehorse doesn't make it to the winner's circle in "The Adventure of the Vanishing Favorite." A jockey loses a race and his life in Crime and Peter Chambers (originally aired on NBC on August 3, 1954). And John Gielgud and Ralph Richardson are Sherlock Holmes and Dr. Watson in an adaptation of "Silver Blaze."

We're riding the subway and walking the Great White Way with four radio gumshoes in New York. First, there's a dead body in Richard Diamond's office in "The Fred Sears Murder Case" (originally aired on NBC on June 5, 1949). A man is killed in Times Square by a man with only a month to live in "The Earl Lawson Murder Case" from Broadway is My Beat (originally aired on CBS on June 9, 1951). John Lund heads to the Big Apple in "The Independent Diamond Traders Matter" from Yours Truly, Johnny Dollar (originally aired on CBS on November 24, 1953), and Captain Kennelly and his men keep the city safe in 21st Precinct (originally aired on CBS on January 13, 1954).
