Michael Oren’s thriller “Swann’s War” takes place on the small New England island of Fourth Cliff, “a world utterly cut off from the real one.” It’s 1944, and World War II still rages.
In charge of keeping the peace is Mary Beth Swann, who serves as the island’s de facto police captain while her husband, Archie, fights overseas.
For the past two years the island has held a camp for Italian POWs.
The prisoners, a mostly congenial lot, are well-tolerated by the locals and encouraged to take work on the docks.
But one morning, fishermen find the corpse of one of the Italians in their nets; the man has been strangled and then dumped in the sea.
