"The tomb of Ts'in" by Edgar Wallace is an adventure-thriller novel written in the early 20th century. It centers on a dangerous hunt for the legendary tomb of China’s First Emperor, mixing crime, espionage, and archaeology. The key players include the flamboyant adventurer Captain Ted Talham, the brilliant Italian sleuth Signor Tillizinni, the poised Yvonne Yale, and the ruthless Mr. Soo, all entangled with a murderous secret society and a priceless jade clue. The opening of the story introduces the stakes through repeated attempts to rob a ship’s safe carrying a Chinese Embassy mailbag, leading Tillizinni to the Ambassador, whose historical article about the First Emperor’s burial becomes the catalyst for intrigue. Talham rescues Yvonne from Chinese pursuers in Hyde Park and deciphers the inscription on her ancient jade bracelet—directions that seem to point toward the tomb—before persuading her to let him hold it for safety. Soon after, the Ambassador is found strangled and a Chinese assailant shot dead in a bureau drawer; a vital envelope is empty, and the suave Mr. Soo emerges as a formidable rival, mobilizing his secret-society network. As deceptions multiply—a fake bracelet is swapped, two burglars (Talham and Tillizinni) collide in de Costa’s house, and a bomb nearly kills the detective—the strands tighten around the tomb’s secret, with social niceties masking a deadly contest for the true jade clue.
