1916, Bois de Bolante, France. The battles in the trenches are raging fiercer than ever. In a deserted mineshaft, French sappeurs discover an unconscious man, and nickname him The Mole. Claiming he has lost his memory, The Mole is convinced that he's dead, and that an Other has taken his place. The military brass considers him a deserter, but front physician and psychiatrist-in-training Michel Denis suspects that his patient's odd behavior is stemming from shellshock, and tries to save him from the firing squad. The mystery deepens when The Mole begins to write a story in écriture automatique that takes place in Vienna, with Dr. Josef Breuer, Freud's teacher, in the leading role. Traumatized by the recent loss of an arm, Denis becomes obsessed with him, and is prepared to do everything he can to unravel the patient's secret. Set against the staggering backdrop of the First World War, The Shadow Of The Mole is a thrilling tableau of loss, frustration, anger, madness, secrets and budding love. The most urgent question in this extraordinary story is: when, how, and why reality shifts into delusion?
