"Enemy to those who make him an enemy, friend to those who have no friend" is how Boston Blackie was introduced to radio listeners, and the former jewel thief turned detective proved week after week that he was always ready to lend a hand to a friend or throw a punch at a criminal. Richard Kollmar stars as the charming rogue who uses all of the tricks of his trade to turn the tables on dangerous crooks in three syndicated old time radio mysteries: "The John Austin Murder," "The Armored Car Murder Case," and "The Bombing of Joe Ingalls."
