Scotland, 1983. Craig Dunlop is bored. Bored of his job, his town, his life. After a family bereavement, Craig inherits an old heirloom; a wallet given to his grandfather during the war by none other than the deputy leader of Nazi Germany, Rudolf Hess. The wallet has hidden a secret for forty years, and when Craig stumbles upon it, a chain of events is set in motion that lead to him becoming a hunted man. Finding himself in a race to unravel a mystery that could shake the very foundations of the British establishment, Craig must find answers before the police catch up with him, or worse still, he is made to disappear forever, along with the secret of The King's Prerogative.
