Proof of Guilt

London, summer 1920. An unidentified body appears to have been run down by a motorcar, and Ian Rutledge is leading the investigation to uncover what happened. While signs point to murder, vital questions remain. Who is the victim? And where, exactly, was he killed?

One small clue leads the inspector to a firm built by two families, famous for producing and selling the world's best Madeira wine. Lewis French, the current head of the English enterprise is missing. But is he the dead man? And do either his fiancée or his jilted former lover have anything to do with his disappearance—or possible death? What about his sister? Or the London office clerk? Is Matthew Traynor, French's cousin and partner who heads the Madeira office, somehow involved?

The experienced Rutledge knows that suspicion and circumstantial evidence are not proof of guilt, and he's going to keep digging for answers. Alone in a no-man's land rife with mystery and danger, Rutledge must tread very carefully, for someone has decided that he, too, must die so that cruel justice can take its course.
