The year is 1937.
"The Japanese have invaded northern Shanghai, and a fierce battle rages across the city, but the International Settlement is an island of safety. When an American seaman is found shot on the edge of the urban battleground, Doug Bainbridge is assigned to investigate for the navy. But what seems a case of foolhardy drunken daredevil sightseeing gone wrong becomes more sinister when Doug learns it wasn't a Chinese or Japanese military gun that shot Seaman Nick Bonadio. His was no accidental death. Can Doug solve Nick's murder before the murderer comes for him?"
