October 1815: There is only one place Kendra Donovan wants to travel—back to her own time period in the twenty-first century. But since that’s not happening, she agrees instead to travel with her new guardian, the Duke of Aldridge, to one of his smaller estates in Lancashire. Their journey takes them through Yorkshire, a region whose breathtaking beauty masks a simmering violence brought on by the Industrial Revolution, which pits mill owner against worker.

When Kendra and the Duke encounter a band of Luddites on a lonely, fog-shrouded road, the Duke informs the authorities in the nearby village of East Dingleford that mischief may have been done at the local mill. However, it isn’t just mischief but murder that is discovered, when the body of the mill manager, Mr. Stone, is found brutally bludgeoned to death in his office.

The Constable is certain the radical-minded Luddites committed the murder. One look at the crime scene and Kendra knows they did not, prompting the Duke to shock the locals by volunteering their services to catch the real killer. Joined by lover Alec and Bow Street Runner Sam Kelly, Kendra must sort through the puzzle of Stone’s rather unsavory life, picking apart alibies and dissecting carefully created deceptions from a growing list of suspects.

As a special agent for the FBI, Kendra thought she’d encountered every kind of evil. But when another, even more vicious murder rocks East Dingleford, Kendra realizes that they’re dealing with a stone-cold killer—one who has a shocking secret that he will do anything to protect.
