The vengeance of Li-Sin

the long version

"Jack Mallory steals a sacred idol from the temple of Tsao-Sun and brings it back to England. It contains priceless jewels, hidden by Chinese priests, and is booby-trapped to explode if tampered with. Meanwhile, Prince Li-Sin tries to kill Jack; a family friend, Dr. Hartley, saves him. But Jack will pay a heavy price for his theft. For both Hartley and Sir Edward Mallory have received the same threatening letter: 'The vengeance of Li-Sin will overtake you'..."--Publisher description.
