World War II is raging, and while the RAF struggles to keep the Luftwaffe at bay, Britain faces a sinister threat from “the enemy within”—Nazis posing as ordinary citizens.
With pressure mounting, the intelligence service appoints two improbable 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 far from an easy stroll along the promenade—N and M have just murdered Britain’s finest agent and no one can be trusted.
Who are the real killers? And why does Delia keep insisting that she committed the crime?
Another classic crime novel by a master of the genre!
