England, 1191. After the death of her friend and patron, King Henry II, Adelia Aguilar is living in retirement and training her daughter, Allie, in the knowledge of anatomy, forensics, and sleuthing. When a friend in Cambridgeshire falls ill, Allie is sent to Ely, where several local girls have vanished. A body is found, and after inspecting the corpse, Allie suspects that a monstrous predator is on the loose. Will her training and her stubborn pursuit of the truth help her find the killer, or make her the next victim? If Allie survives, Queen Eleanor of Aquitaine intends to find her a high-born husband, one way or another—yet Allie has just met the man she would want to marry. When Ariana Franklin passed away in 2011, her daughter Samantha Norman completed this novel, the final installment in the saga of Adelia Aguilar, which began with Mistress of the Art of Death.
