Wounded dectives are not always allowed to sit around comfortably and recouperate.  John Corey was pulled into a murder-treasure theft situation by knowing the right people – those who were murdered.  Luckily some of his friends taught him about manuvering a boat in Long Island Sound and about the animal disease research site at Plum Island (before they were killed because of their knowledge).  In this story one learns a lot about the way a dective’s mind works, helping to sort out facts from feeliings and put them in a logical order that points the direction of the crime.  it is also very interesting to learn about things that may have happened to Captain Kidd’s treasure.
