Could Fitzwilliam Darcy harbour a shocking, sinister secret?

Mr. Darcy and Elizabeth Bennet count themselves among the many guests of the Kendall family, whose estate lies amidst the picturesque hills, gorges, and rocky slopes of the Peak District in Derbyshire. Elizabeth's cousin, Rose Kendall, believes her dashing brother-in-law, Captain James Kendall, is Elizabeth's ideal match. Rose's husband, Nicholas, hopes his good friend Darcy-a rich, proud, and taciturn gentleman with a spotless reputation-will fancy one of the other eligible lady guests.

News of a brutal killing at a neighbouring estate sends a wave of shock through the genial group of friends and family. When one of the Kendalls' guests is attacked, all of the gentlemen become suspects, but the former Bow Street runner tasked with investigating the crime finds the evidence against Mr. Darcy particularly compelling.

In this romantic mystery, the beloved couple from Jane Austen's Pride & Prejudice cross paths with a ruthless killer. When faced with dire warnings against Mr. Darcy, will Elizabeth heed them or follow the dictates of her heart?
