The Losing Role (Kaspar Brothers #1)
by Steve Anderson
In the last winter of World War II a failed German actor, Max Kaspar, is forced to join a desperate secret mission in which he must impersonate an enemy American officer. So Max cooks up his own fanatical plan -- he'll use his false identity to escape tyranny and war and flee to the America he'd once abandoned.
The Losing Role is the first book in the Kaspar Brothers series.
