Detective Comics #364

Detective Comics #364 (On Sale: April 27, 1967) has a fairly cool cover by Carmine Infantino and Murphy Anderson.

"The Curious Case of the Crime-Less Clues" is by Gardner Fox, Sheldon Moldoff and Joe Giella. Batman and Robin stop several crimes. At each crime scene they find strange clues that seem to have been left by their arch-enemies. However, each of the villains in question is already in prison. After receiving the final clue Batman realizes that their Founder's Day float is being targeted. Batman sets a trap, but when the float explodes the villain behind the attack fails to reveal himself.

The Elongated Man back-up "The Ship That Sank Twice" is by Gardner Fox and Irv Novick. Ralph Dibny and his wife witness a man purchasing a boat that he knows will sink the first time he puts it in the water. Curious, Ralph follows the man and watches the boat sink near a freighter. The man is taken aboard the ship, which was his plan all along.
