Kate Rees, a young American markswoman, has been recruited by British intelligence to drop into Paris with a dangerous assignment: assassinate the Fuhrer. Wrecked by grief after a bombing killed her husband and daughter, she is armed with a rifle and a fierce resolve. But she has no formal spy training. Thrust into the red-hot centre of the war, a country girl from rural Oregon finds herself holding the fate of the world in her hands. When Kate misses her mark and the plan unravels, Kate is on the run for her life - all the time wrestling with the suspicion that the whole operation was a set-up.
