Following the 1916 Easter Rising, anyone who served with Britain in the war is now thought a traitor, including nurse Eileen Flynn and Michael Sullivan, who plan to marry in the village where she grew up. Bess Crawford has come to see Eileen wed, despite the risk, but in this 12th mystery (following A Cruel Deception), the groom has vanished—and then a body is found. Eileen begs for her help, but in this bitterly divided land, how can Bess possibly save herself, much less stop a killer?
