February 1917. The Germans may not be the only enemy on the Western Front. A young officer is haunted by nightmare recollections of the Battle of the Somme and shackled to a desk at the War Office as he attempts to come to terms with his experiences in France. But trouble has a knack of finding Captain Will Stanley. The last time he was on the Western Front, he was dying. But now one man has been murdered in gruesome fashion, another has vanished into thin air and the actions of Captain Stanley's own former battalion may have grave connotations for the Allied war effort. In the midst of the coldest winter that Europe can remember, Captain Stanley is about to be called back into action. Battling against events he cannot control and against his own mental debilitation, he must attempt to unravel the case, ascertain the extent of the damage to Allied plans and discover the fate of the man who returned to save his life; when all others had left him for dead.
