A Scotland Yard detective hunts down a mysterious international crime ring in this thriller by the author of the Fu Manchu novels.
Across London, brilliant scientists are dying of strange causes and Scotland Yard suspects foul play. When Inspector Dunbar seeks the advice of Dr. Stuart, an expert in exotic poisons, he learns that the good doctor has been experiencing mystifying troubles of his own. But Dunbar is shocked by yet another development: he’s informed that his friend, French detective Gaston Max, has been found dead in the Thames.
Max had been investigating a criminal mastermind known as the Golden Scorpion, and evidence suggests the cases may be related. As Inspector Dunbar and Dr. Stuart seek out the illusive figure—they encounter deadly stakes and shocking twists—because not all the Golden Scorpion’s victims are as dead as they first appear.
