In this 15th adventure of the series, Peter Sharp's privacy has been invaded: a person with a grudge against him knows that Peter is a devout fan of mysteries, especially those featuring Sherlock Holmes... and some events take place in banks that have traces of elements coinciding with the characters and occurrences in the Holmes stories, but the FBI doesn't think they merit investigation, so they bounce the matters down to offices of the Los Angeles District Attorney, who is Peter's ex-wife Myra, who asks Peter to look into these matters to determine whether or not these events are merely the jokes of some pranksters, or if they are hints of a serious upcoming crime that will take place. If you have ever enjoyed a Sherlock Holmes mystery, you'll enjoy reading about this gang weaves several of them into this adventure. This is the first adventure in which Peter's legal ward Suzi's huge Saint Bernard may accidentally provide information that can solve this case. You'll also enjoy trying to match wits with little Suzi (and her dog) in this case.
