Most of this book is indeed in the form of a narrative, and a good alternative title for it would be "The Mystery of the Monte Carlo Lock," since the last half concerns a case which inspector Craig of Scotland Yard must discover a combination that will open the lock of a safe in Monte Carlo to prevent a disaster.
