The aging Mr. Big of the Gotham underworld, Li'l Studs, is being given a "welcome home" banquet by gangsters following a stay in the hospital. Quirk, one of Studs's competitors, has hired three hitmen to rub him out: a crack pistol shot named the Silencer, a poison-dart hurler called the Dart, and Big Jolt, a specialist in electrocution. Bruce Wayne and Dick Grayson are posing as waiters to avert such a hit-attempt, and thus stave off a gang-war amongst the other mob chiefs for Studs's place. Studs indeed dies, but none of the mobsters can agree as to how he was killed, since all three of the assassins struck at the same time. With help from Dr. Jennings, a doctor who treated Li'l Studs, Batman discovers the truth: Studs died of a heart attack before any of the assassins could kill him. Qu
