S1·E29 The Bookworm Turns

Commissioner Gordon appears to have been assassinated during the opening of a new bridge. A copy of Hemingway's 'For Whom The Bell Tolls' nearly blows up the Batmobile. Both incidents are clues to the Bookworm's latest scheme. Batman and Robin interrogate The Bookworm's henchwoman Miss Limpet but deduce she is leading them into a trap. And while Batman intends to walk right into it, it is Robin who falls first.
