The Golden Scorpion — Sax Rohmer

Four brilliant men have died mysteriously -- and the only clue is the carved tail of a golden scorpion, left beside their bodies. The man behind the horror calls himself "The Scorpion," and he clearly is a man of superior cunning. When the finest detectives of France and England join forces to stop "The Scorpion" before he can add a fifth victim to his list, the twisting trail takes them through the haunts of London's underworld to the seamy opium dens of Chinatown -- and from there into "the Lair of the Scorpion."
