But when a high-society call girl commits suicide in one of the Beaumont's suites, Pierre learns she'd been under pressure to murder Moon. He also discovers that there is a "Moon Club" made up of people with good reasons to wish the man dead. When an anonymous big spender offers $10,000 to any club member able to exterminate the menace, Chambrun works with his chief of security and the NYPD to catch the mastermind before the plot—and Moon—are executed.
