Ante up for three radio mysteries involving gamblers and the sometimes deadly bets they make. First, a pet shop owner is killed when he refuses to offer his store as a front for a gambling ring in Boston Blackie. Then, a real-life Chicago reporter cracks the case of a poker game that ends in murder on The Big Story (originally aired on NBC on April 4, 1951). And finally, Sgt. Joe Friday hunts for floating games in the City of Angels in "The Big Gamble" from Dragnet (originally aired on NBC on May 8, 1952).
