With pressure mounting, the intelligence service appoints two unlikely spies, Tommy and Tuppence Beresford. Their mission: to seek out a man and a woman from among the colorful guests at Sans Souci, a seaside hotel. But this assignment is no stroll along the promenade—N and M have just murdered Britain's finest agent and no one at all can be trusted. . . .
