S1·E4 The Adventure of the Comic Book Crusader

Ellery himself is a leading suspect in the murder of a comic book publisher with whom he'd clashed over how he was portrayed in the publisher's comics. It seems as though the man left a dying clue which apparently points to him. Ellery is forced to investigate in order to clear his name. Ole Frank Flannigan is on the scene too trying to steal some of the glory.
