Freeport attorney Gabriel “Gabby” Gordon rehabs old houses when not practicing law. When she purchased Babcook Manor, a six bedroom 1920s era mansion for one of her projects she was told that the place had been uninhabited for over fifty years. Just as she finishes the 3-year rehab she is contacted by John Galway, an elderly resident of a nursing home. While Galway appears to be suffering from dementia, Gabby is not so sure once she meets him and he claims to have lived secretly in the basement of the mansion for forty years. When a background check reveals that he was once a sniper in the OSS and then for the CIA, Gabby begins the process of unwinding the secrets of Babcook Manor and John Galway. An oily Chicago attorney, Swiss bank accounts, and a couple enforcers for a bookie add to the complications.
