In this fourth installment of her much-loved World War I mystery series centering on the intrigue and escapades of the Reavley family, Anne Perry brings her considerable creative writing talents to this historical setting once again.
The story opens in mid-July 1917 on the Western Front. It has been three years of latrines, corpses and poison gas for Chaplain Joseph Reavley. The war has dragged on longer than anyone predicted, and Joseph has had to write too many condolence letters to surviving family members. The losses have been overwhelming.
