Ormond Sacker's military training, international travels, and experience of curious crime, together with an intimate relationship with the works of Sir Arthur Conan Doyle, have given him a unique view of the world. Such a character is clearly the ideal author of a book of Holmes-based conundrums and problems. He has also written A Sherlock Holmes Escape Book: The Adventure of the Two Flying Scotsmen and A Sherlock Holmes Escape Book: The Adventure of the Train of the Dead.
