In a library, in a book, in a photograph, Phil Marlowe sees something which instantly changes his life. He seems to have evidence that in a previous existence he was the man who plunged the world into war and who called himself a 'dreamwalker': Adolf Hitler. Struggling to regain normality, Phil is assisted by his friend David who devises an ingenious test to determine whether Phil really is reincarnated. Meanwhile, a dying old man sets him on a quest to find documents, a place and a woman. His search leads to 'Shelburne' and a new take on mysteries surrounding Hitler's first war. In pursuit of Shelburne, Phil learns about a Breton called Morvan Lubbock who appears to have had dealings with Hitler. Is Morvan's story true? Who sent him? Who was betrayed? If Phil can find the answers to these questions then David can say whether Hitler really has returned, or if Phil is merely another dreamwalker.
