A terrifying international plot threatens the agents of Britain's Department Z in this tale of suspense from an Edgar Award–winning author. Leopold Gorman studies the World Economic Conference with interest—and then picks five rich and powerful men to bring his plan to fruition. If any one of them shows reluctance to fall in with his scheme, he'll be dead within the hour . . . Gordon Craigie, chief of British intelligence, is the only thing standing between Gorman and success. So Gorman turns his attentions to Craigie's greatest asset: the men of Department Z. As Craigie attempts to undermine Gorman's plot, Gorman decides which agent should be next to "disappear." Can Craigie and his men outwit this master criminal before it's too late?
