The Man from the Train is a 2017 true crime book written by Bill James and his daughter Rachel McCarthy James. In The Man from the Train, the authors claim to have discovered the identity and existence of a previously overlooked serial killer active in the late 1800s and early 1900s. According to the authors, this criminal was named Paul Mueller, who operated throughout North America and killed a minimum of 59 people and possibly over 100. In the early 1900s some of these crimes were attributed to a suspected killer known as Billy the Axeman, but the authors suggest the killer was responsible for a wider range of crimes than earlier thought. Bill James is best known as a baseball analyst using sabermetrics, but also writes about crime, having previously published Popular Crime: Reflections on the Celebration of Violence (2012).
