James Stonehouse

James Stonehouse was a resident of 1820 Liverpool, who prided himself on having a more "robust and rational" man than Joseph Williamson. He questioned Williamson insistently about the purpose of the mysterious Tunnels whose digging Williamson was sinking so many resources into, but Williamson, while insisting that his tunnels did have a rational purpose, refused to reveal it to Stonehouse.

Behind the scenes
James Stonehouse was a contemporary of Joseph Williamson who explored his tunnels extensively and made sketches and accounts of them which have proved to be valuable historical documents in studies of Williamson's life. The historical Stonehouse, however, was born in 1809 and would thus have been much younger than Williamson in 1820, contrary to what is depicted in The Halloween Apocalypse.
