This is a fascinating book, well-written and thoroughly researched. It is about a real private detective, yet at times it reads like a novel. In addition to telling the story of Henry Slater, this book discusses identity in Victorian society including class and gender. Even the parts of the book that feel slower are interesting in painting a portrait of Slater and the society in which he lived. I was totally engrossed, even while I was appalled by some of the actions that were pertinent to the trial. Fans of historical true crime (that doesn't involve murder) and Sherlock Holmes will likely find this book interesting.

Thank you to NetGalley and Pen & Sword for the free eARC! I post this review with my honest opinions.
