Romance Historical
A scandalous widow. A wounded spy. And a passion that could expose a deadly conspiracy.
Simon Clark, Earl of Astley, is London’s most notorious rogue—and a spy for the Crown whose rescue from a French prison may have come too late. His memory is fractured, his enemies are closing in, and the secrets he uncovered could cost him his life.
Lady Caillen Griffith never expected to see Astley again. Once he was a menace to her peace; now he is the man who saved her life the night she lost everything. Widowed and determined to uncover the truth behind her father’s death, Caillen appoints herself Astley’s caretaker—whether the infuriating earl wants her help or not.
Forced together beneath one roof, old clashes ignite into something far more dangerous. Simon is determined to revive the fire he sees buried beneath Caillen’s grief—but the deeper she digs into classified information, the more lethal the truth becomes.
Because someone will kill to keep those secrets buried… and loving each other may be the greatest risk of all.
The Wicked Baroness by Helene Matheson delivers a gripping Regency romance where espionage, danger, and desire collide.
