In a day in June, at the hour when London moves abroad in quest of lunch, a young man stood at the entrance of the Bandolero Restaurant looking earnestly up Shaftesbury Avenue—a large young man in excellent condition, with a pleasant, good-humoured, brown, clean-cut face. He paid no attention to the stream of humanity that flowed past him. His mouth was set and his eyes wore a serious, almost a wistful expression. He was frowning slightly. One would have said that here was a man with a secret sorrow.
