JFK is in the Oval Office. "Love Me Do" is climbing the charts. And in West Berlin, a wealthy ex-black marketeer, the Dane, is offering a stolen spy satellite for sale. Nothing unusual there, except the asking price: half a billion dollars. Too much for any satellite—unless it's Hitler's legendary, long-lost Project Archangel.

Archangel, it's rumored, is a device capable of shifting the balance of the Cold War. To find it, Mallory and Morse fly to the Monaco Grand Prix and infiltrate the Dane's entourage: a pair of lovely and vicious blonde twins, a ravishing Polish giantess with a taste for movie magazines, and an American ex-mercenary with quiet eyes and hands like stone. The Dane is both a perfect host and a savage killer, and has already done one of the Consultancy's agents to death. But their greatest peril may come from the long-buried passions of the icily beautiful Laura Morse. . . .
