The Armistice of November 1918 ended the fighting, but the Great War will not be over until a Peace Treaty is drawn up and signed by all parties involved. Representatives from the Allies are gathering in Paris, and already ominous signs of disagreement have appeared. Sister Bess Crawford, who has been working with the severely wounded in England in the war's wake, is asked to carry out a personal mission in Paris for a Matron at the London headquarters of The Queen Alexandra's. Bess is facing decisions about her own future, even as she searches for Lawrence Minton. When she finally locates him, instead of the intelligent, ambitious officer she expects, she finds a bitter and disturbed man who has abdicated his duties at the Peace Conference and is well on his way toward an addiction to opiates. Indeed, he tells her that he doesn't care if he lives or dies, he only wants oblivion. But what has changed him? What is it that haunts him? It seems the truth is buried so deep in his mind that he can only relive it in wild nightmares. When Minton goes missing, bent on suicide, Bess must race to unlock his past before he succeeds. Reluctant to trust an officer in Minton's regiment, a man with secrets of his own, and uncertain of the loyalties of Matron's friends in Paris, Bess must rely on her own instincts and experience -- and sometimes in desperation on a stranger who claims he never met Minton. Could whatever happened to Minton in Paris somehow be connected to his war? And why did he not kill Bess when he had the chance -- then later, viciously attack her without warning? What is destroying Lieutenant Minton? Or is it who? And what horror will she have to confront, if she is to save him?
