Tommy Berecford and Tuppence Cowley are a real sweet couple. But there is one problem: they have no money, no job, and they are always broke. Then in their heads comes the decision to open their own enterprise "Young adventurers Ltd . And they are the best at cheating........... [ And here's the first order from a certain Mr. Whittington .. [ [ ] The fee for the services is excellent, but the matter is so strange that Tuppence decides not to reveal his real name and appears to be a name that she accidentally overheard in a conversation with another person in Whittington’s life......... And suddenly the customer changes in person, hastily leaves, for some reason giving Tuppens a large amount of money, and soon disappears without a trace from the horizon of adventurers. Curious Beresford and Cowley want to know who this Whittington is and why he is so afraid of the name Jane Finn.
