England. The end of the 19th century. Seventeen-year-old Audrey Rose Wadsworth is the daughter of one of Britain’s influential lords. But instead of fashionable dresses and a future—undoubtedly a brilliant marriage—her thoughts are occupied by forensic medicine, anatomy, and other activities improper for a young aristocrat. This “hobby” would have remained her secret, shared only with her uncle, surgeon and doctor Jonathan Wadsworth, and his brilliant student Thomas Cresswell, if the most terrifying serial killer had not appeared in London—Jack the Ripper. Audrey Rose resolutely joins the investigation, but soon begins to suspect that the maniac is hiding behind the mask of someone close to her. But who is this madman?
