Returning to the States, battle-fatigued war correspondent Bob Rivers finds it difficult to unwind in Nantucket when his provocative neighbor Meri becomes the victim of surveillance, break-ins and dead prowlers. The goings-on seem to be connected with both the suspicious death of her journalist fiance the previous year and with Rivers' politically aspiring publisher Tim Hoffmann. Is it really Tim who's about to get his party's nomination for president. . . or could it be his look-alike German cousin, Konrad von Hoffmann, a Communist sleeper agent who may have taken his place during WW II? The Democratic National Convention looms hours away. . . the only other serious candidate is steadily losing ground thanks to his promiscuous wife. . . will Rivers and the CIA be able to make the real Hoffman stand up in time? A circuitously obvious soaped-up item.
