The Doctor and the Dead Man's Chest — Robin Hathaway

Dr. Andrew Fenimore is an old fashioned doctor who is still willing to make house calls to his elderly patients. In his third adventure, a patient's call leads to more detection than medical care.

Lydia Ashley, owner of a large farm in Southern New Jersey, is being systematically harassed by someone who wants her land. Dr. Fenimore can't leave his Philadelphia practice, so he sends his nurse Mrs. Doyle and his young assistant Horatio to try to stop the attacks, but the threats continue. When Mrs. Doyle is kidnapped, Dr. Fenimore joins the hunt and learns that hidden treasure is at the root of all the evil deeds.
