Thirty-five-year-old Jonathan Wraith — a young British millionaire by virtue of selling his and his father’s portable cabin business for £30 million ($46 million) — was by all accounts a happy and well-adjusted young man. However, in 2009 he picked up his shotgun and shot himself, leaving no suicide note. No clear reason could be found for Wraith’s action.
