The Feathered Serpent is a mystery-thriller novel penned by the remarkably prolific Edgar Wallace. A number of people receive threatening cards emblazoned with the device of a feathered serpent, a device that we later find is associated with ancient Aztec religion and with a cult that still exists in Mexico and Central America. Reporter Peter Dewin suspects the card mysteriously left in the handbag of actress Ella Creed is a publicity stunt. He soon discovers that a wealthy artist, a boxing promoter and a nouveau riche stockbroker share her fear. Then, after leaving the house of millionaire philanthropist and African explorer Gregory Beale, Daphne Olroyd is followed. The Feathered Serpent case will eventually lead to murder and two kidnappings. Who is behind the crimes of The Feathered Serpent?
