Drums of Fu Manchu

Immediately before World War II, Fu-Manchu decides to kill or control the world’s war-mongering dictators, to pave the way for his own plans. The rapid-fire action moves from London to Venice to Paris, and involves various arcane and scientific forms of torture and death.
BONUS FEATURE: The Mark of the Monkey, the second of three lost adventures of Nayland Smith. It appeared in Collier’s in 1931, then in the short story collection Tales of East and West.
