Books like Why kings confess by C. S. Harris

In January 1813, a badly injured Frenchwoman is found beside the mutilated body of Dr. Damion Pelletan in London’s poorest slum. Sebastian St. Cyr, an aristocratic private investigator, and his pregnant wife Hero are drawn into a high‑stakes investigation. Sebastian recognizes the woman, Alexi Sauvage, from a wartime atrocity that scarred his past. As he probes Pelletan’s murder, he discovers the doctor was part of a clandestine Napoleonic delegation seeking peace with Britain. Ignoring his father‑in‑law’s warnings, Sebastian follows clues to the "Lost Dauphin," a boy prince who vanished during the French Revolution, and finds himself confronting the Dauphin’s ruthless sister, daughter of Marie Antoinette, who seeks to reclaim the French crown. With the killer closing in, Sebastian must protect Hero’s health, their unborn child, and confront the truth about his own past guilt.
