Detective Comics #364

In "The Curious Case of the Crime-less Clues!", Batman and Robin investigate a series of baffling crimes that seem to point to their archenemies—except each suspect is already behind bars. With a clever twist involving a drop of glue in screw holes to reform damaged threads, the duo unravels a mystery that defies logic. Written by Gardner Fox and illustrated by Sheldon Moldoff, with inks by Joe Giella and letters by Gaspar Saladino, this 1967 tale features a cover by Carmine Infantino and Murphy Anderson.
