Distinguished British diplomat Sir John Little seems to be living out his days quietly in retirement. But then, at his beach house in the Bahamas, he goes for a swim - and doesn't come back. Was it an unfortunate accident, suicide, or a well-planned murder? British Foreign Office employee Michael Burton and Bahamian detective Chester King are given the job of finding out. With little to go on, and still less volunteered by the diplomat's enigmatic wife and the unexpected heir who practices black magic, Burton and King discover that all is not what it appears.
