Features fantastic world-building, a gripping mystery, and an enjoyable rendering of the Holmes / Watson partnership. I particularly liked the author’s take on a Roman Empire that has (at least some) honorable servants who wish to protect the public. 

Enjoyed a small chuckle when a character reflects that the taste of tobacco really helps his thinking along; very Arthur Conan Doyle. The society’s enhancements and body modifications stand in for Sherlock’s heroin, I guess.
