"Angels in the gloom" is an intense saga of love, hate, obsession, and murder that features an honorable English family. Brothers Joseph and Matthew Reavley, and their sisters, Judith and Hannah. In March 1916, Joseph, a chaplain at the front, and Judith, an ambulance driver, are fighting not only the Germans but the bitter cold and the appalling casualties of the Battle of Somme. Scarcely less at risk, Matthew, an officer in England's Secret Intelligence Service, fights the war covertly from London. Only Hannah, living with her young children in the old family home in tranquil Cambridgeshire, seems safe.
