In this absorbing and atmospheric historical mystery from New York Times bestselling author Charles Todd, World War I battlefield nurse Bess Crawford's career and life are in jeopardy when a murder is committed on her watch

Bess Crawford has been summoned by the War Office to accompany a wounded soldier from Shropshire to Buckingham Palace, where he's to be decorated for gallantry by King George himself.

Heavily bandaged and confined to a wheelchair, Sergeant Jason Wilkins will be in her care for barely a day. But on the morning after the ceremony when Bess goes to collect her charge for his return journey, she finds the room empty. How could such a severely wounded man vanish without a trace?

Both the Army and the Nursing Service hold Bess to blame for losing the war hero. The Army now considers Wilkins a deserter, and Scotland Yard questions Bess when Wilkins is suspected of killing a man in cold blood. If Bess is to clear her name and return to duty in France, she must prove that she was never his accomplice. But the sergeant has disappeared again and neither the Army nor the police can find him.

Following a trail of clues across England, Bess is drawn into a mystery that seems to grow darker with every discovery. But will uncovering the truth put more innocent people in jeopardy?
