From The Shadows

US Army Captain Billy Boyle plunges into partisan warfare alongside betrayed French Resistance fighters in his seventeenth WWII investigation.

Southern France, 1944: Ex-Boston cop and wartime military investigator Billy Boyle is given a dangerous assignment—to extract a British Special Operations Executive officer from Crete and take him to France to serve on a security detail to identify fascist sympathizers. The mission gets even more complicated when Billy realizes how many enemies the officer he must protect has accrued. In the aftermath of the failed, and costly, Vercors uprising, tensions among Resistance groups are running high, and the mission turns far deadlier than expected.

On the quest to weed out Vichy collaborators, Billy takes up an independent investigation to exonerate an innocent comrade of murder. In the process, he crosses paths with the legendary SOE agent Christine Granville and the heroic 442nd Regimental Combat Team, made up of Nisei soldiers who are already on their way to becoming the most decorated unit in the history of the US Army.

With sacrifice and subterfuge afoot, Billy doesn’t know who he can trust, or how close to death this case may bring him.
