A young man is found unconscious in a park in London. He has no injuries, no illnesses. Weeks later, the doctors still can't explain why he hasn't regained consciousness. A detective, a homeless man and a writer try to find answers to the questions surrounding him. A widely traveled elderly man is working on his memoirs. He had left home at the age of nineteen. The decades that followed were dominated by his determination to overcome professional and personal adversities. About half way through the book, the young man and the elderly man meet under extraordinary circumstances - they "collide," may be a better word - and seemingly unanswerable questions emerge. One man's search for answers takes him around half the globe to Western Australia. The Mysterious Man is a major novel that encompasses three genres: literary fiction, mystery and memoirs.
