When the body of a young woman is found near the ruins of a haunted abbey, everyone assumes she died of fright. A postmortem examination tells a different story. Not only was Elizabeth Barrett poisoned, but the lethal dose of cyanide must have been administered by someone close to her-someone she trusted, who may have known her secret.

As Captain Redmond and Constable Haze delve into the victim's seemingly ordinary life, they learn she wasn't the proper, biddable wife everyone believed her to be. With no clear motive for the murder and no obvious suspects, the trail soon grows cold. But the killer is closer than they imagined, waiting to strike with deadly force should they discover the truth.
