On the Western Front in World War One, the savage battle of Paschendaele has begun. Morale is low as the senseless fight to gain a few yards rages on. The soldiers clash amid the stench of death and the despair of seeing their fellow comrades die due to the incompetence of a senior officer's orders. It's the combination of arrogance and the inability to heed advice that causes the men to rebel and kill their superior officer. Having ministered and aided the soldiers, Chaplin Joseph Reavley becomes their advocate as they are court-martialed. His sister, Judith, an ambulance driver, attempts to help but only makes the situation more critical.

While Judith and Joseph struggle on the front lines, their younger brother, Matthew, works in the Intelligence Unit trying to isolate the Peacemaker. The Peacemaker and his organization conspire to sabotage and eliminate men working for lasting peace. He wants a world dominated by strong leaders, such as Lenin, who will ensure a utopian life with equality and no wars. Matthew can't trust anyone, even his superiors, as he races to stop the latest plot from the Peacemaker.

This fourth installment in Anne Perry's brilliant WWI series raises questions about honor, values and humanity. She poses the question: How much can we ask of soldiers as they become disillusioned with their leaders and what they perceive as hopelessness in the trenches? AT SOME DISPUTED BARRICADE is a thoroughly thought-provoking novel about war.
