. . . is--who else?--Jonas Wilde, presumably in retirement in Spain, when he's recruited by Jonquil Malone (met several books ago) to work as a couple aboard the yacht of the Prince of Xanda, a vital Arab sheik on the side of the Israelis and the Western powers. They're hired to keep him alive, but then there are two lovely young women who are also his bodyguard (a double-duty word if there ever was one) and Jonas only realizes who serves what interests before the final spritz of gunfire. Need it be added?--Wilde is as romantically and fatally infallible as ever.
