Edgar Wallace 
Feathered Serpent 

Reporter Peter Derwin suspects the card mysteriously left in the handbag of actress Ella Creed is a publicity stunt. But Joe Farmer, the boxing promoter, has received one too. Then, after leaving the house of millionaire philanthropist and African explorer Gregory Beale, Daphne Olroyd is followed: she is at her employers‘ offices when Leicester Crewe opens the front door. A dead man falls into the hall. In his hand is the card of The Feathered Serpent.
