The Devil Bat
In "The Devil Bat," Dr. Paul Carruthers, a seemingly mild-mannered scientist, harbors a deep resentment towards his employers, the Heath family, who have profited immensely from a product he helped develop. Seeking revenge, Carruthers creates a formula that he applies to a special aftershave lotion, which he gives to members of the Heath family and their associates. The scent attracts giant bats that Carruthers has genetically altered, causing them to attack and kill the wearers of the lotion. As the mysterious deaths mount, a determined reporter, Johnny Layton, and his photographer, "One-Shot" McGuire, investigate the strange occurrences, ultimately uncovering Carruthers' sinister plot and putting an end to his deadly scheme.
