The Fourth Shadow — Robert Charles

Simon Larren merely had to ensure that the visiting President of Maraquilla remained alive during a goodwill tour of the British Crown Colony of San Quito. But there were complications. Maraquilla's President could no longer trust his regular bodyguard, and Larren was hampered by Caroline Brand, the good-time girl who had followed him from London. And finally there was a Communist-inspired bid for illegal independence from British rule, backed by the evil of voodoo.
