March 1915, the war on the Western Front has ground to a halt. Britain cannot manufacture enough munitions to keep fighting, and yet the Allies must find a way to dislodge the German Army from France and Belgium. So when the bodies start piling up at the Royal Arsenal, Lieutenant Will Stanley is recalled from leave to investigate. The stakes are high, for if he does not get to the bottom of this mystery, it could spell not only defeat for the army, but the end of Great Britain and her Empire.
