In this Edwardian mystery, a woman must uncover the truth that will rescue her fiancé from claims of treachery against the English crown.

For heiress-turned-sleuth Ursula Marlow, the stakes have never been higher. Lord Wrotham, love of her life and the man she is to marry, stands accused of treason. Worse, a vow of secrecy keeps her beloved from even attempting to save himself from the gallows. It will be up to Ursula to find the evidence that will return Wrotham to his rightful place by her side.

But with the authorities convinced that Wrotham is behind a plot to sell naval secrets to Kaiser's Germany and liberate Ireland from English rule, Ursula partners with prickly Chief Inspector Harrison to delve into Wrotham's mysterious past. . . .

Drawn into the shadowy world of the Irish Republican Brotherhood and a web of espionage and betrayal, Ursula must race against time to clear Lord Wrotham's name and thwart a plot that threatens not only British national security, but her life.
