This volume includes two of Conan Doyle's most gripping tales. 'The Tragedy of the Korosko' is a thrilling adventure story set in the heat of the Sahara desert, where a group of Europeans find themselves at the mercy of a band of ruthless kidnappers. 'The Green Flag' is a chilling mystery involving a murdered man with a green silk scarf around his neck. With his masterful storytelling and vivid characters, Conan Doyle is at the top of his form in these classic tales.
