What would it be like to be unsure if you could recognize your own brother? That is the disturbing question that Julie Davidge, a young free-lance artist living in London suddenly and bewilderingly finds herself confronted with. Her brother Richard, ten years her senior and always a remote figure to her, has disappeared, presumably kidnapped as a British agent by the enemy. One day a man claiming to be Richard appears in London, and almost simultaneously Julie receives a postcard in Richard's handwriting, saying he is alive in France and needs her help. Is the man in London her brother, or is he an enemy plant, waiting for any clue to the whereabouts of the real Richard in order to have him killed?
I found this book and one day opened it, reading just the first few pages. I soon found I couldn't put it down and in the end I very much enjoyed Stevenson's whole story!
