Hiring themselves out as “young adventurers willing to do anything” proves to be a smart move for Tommy and Tuppence. The first job sounds like a dream. All Tuppence has to do is take an all-expense-paid trip to Paris and pose as an American names Jane Finn. But with the assignment comes a bribe to keep quiet, a threat to her life, and the disappearance of her new employer. Now Tuppence’s newest job is playing detective – because if there’s a “Jane Finn” that really exists, she’s got a secret that’s putting both their lives in danger.
