The Duke's Last Hunt — Rosanne E. Lortz

With her third London season drawing to a close, the shy Eliza Malcolm seems unlikely to find any husband, let alone a titled one. But when the hunting-crazed Duke of Brockenhurst invites the Malcolms to visit Harrowhaven, Eliza's father jumps at the chance to gain a wealthy son-in-law. Surrounded by quarreling parents, tactless acquaintances, the aloof dowager, and the unsettling duke, Eliza looks for one person kind enough to help her navigate the murky waters of Harrowhaven's secrets….

Estranged from his brother the duke, Henry Rowland only planned to visit Harrowhaven for the afternoon, but after meeting his brother's intended, his designs are overthrown. As misfortune strikes Harrowhaven, Jacob Pevensey is called in to investigate. Henry learns that the only way to safeguard Eliza Malcolm's happiness is to face the past he has been running from for ten long years.

This novel takes the medieval events surrounding William II's death in the New Forest and transposes them to a Regency country manor. It is the second book in the Pevensey series, but can be read as a standalone.
