Ninety-year-old Gladys McFadden is certain she’s been robbed. A single item is missing – from a full safety deposit box in the invincible vault at Dawson Bank. Humouring the old girl, Investigator Matthew Traverse opens a case, and asks his retired-thief girlfriend for a professional opinion. In less than a day, Rennie’s looking at a life sentence, while Matt’s career lies in ruins and he’s facing charges of murder. Matthew has only hours to live, unless he can exonerate them both by unmasking a brilliant new ‘Napoleon of Crime’.
