The third and final book in the Empire Of The Wheel series by my guest and former co-host Walter Bosley ties together all of the themes presented so far, and introduces some new evidentiary threads involving horror writer H.P. Lovecraft, the Zodiac Killer and the horrifying activities of a little-known serial killer of the 1920s.

The events center around a rash of unsolved murders in the Inland Empire area of Southern California in the first years of the 20th century.

In the course of his investigations, Walter believes that he also has found evidence that Harry Houdini was targeted for death by the Spiritualist movement because of Houdini’s relentless persecution of members who he claimed were taking advantage of bereaved relatives of the deceased.

Walter also describes some strange shenanigans at the Secret Service archives and National Archives when he asked for a file from 1915, the period of the action in the books. This was the first time he mentioned this turn of events.
