"He Walked Around Horses" is the first short story in the Paratime Police series. It is said that Piper hinged his story on on a report of the disappearance of the British diplomat Benjamin Bathurst; his father was the Bishop of Norwich of the Church of England. His disappearance occurred during the Napoleonic Wars in Germany. His vanishing exit from life kindled much guesswork about what happened to him. Though, most likely he was a victim of foul play.
Piper used this unfortunate disappearance as a jumping off point for his story. In Piper's short story, while journeying home from Austria and traveling through Prussia, Tortha Karf plucked Bathurst up with a Paratime conveyer. He is left in a different timeline that forked off in 1775 at the Battle of Quebec. Benedict Arnold dies from his wound in Piper's story. And other historical changes follow from that divergence.
