No-one knows more about the workings of Dividend Investments than Eddie Fly. He reads all the memos, all the telexes. He hears all the most important telephone calls.

Percy Wheeler, Dividend’s boss, decides to put a woman in his place. Eddie’s carefully-managed world begins to run out of control. And has someone been up to some mysterious dealings on the side?
