Who was Sumuru? It was said that she was an ice-cold, fascinating genius whose hypnotic powers impelled all men to do her bidding. It was said she was a fanatic who ruled her followers with oriental despots. It was said . . . But what was the truth? Nobody really knew although two men knew part of it -- sir Miles Tristram, just returned from Cairo, and Dr. Steel Maitland of the Secret Service. But Tristram died by the hand of a beautiful woman and his secret died with him. That left Maitland alone to follow the trail through Sumuru's shadowy underworld and it almost proved to be a task more than he could handle. In Sins of Sumuru, Sax Rohmer, creator of the famous Fu Manchu novels, has written another masterly story of fear and excitement.
