G'day, Wasn't he the inspiration for Robert Louis Stevenson's Dr Jekyll & Mr Hyde? He used to be a respectable citizen by day, visiting people as a deacon, but actually spying out the properties which he would rob by night. I'm not sure whether he also used to rob graves at night, selling the bodies to surgeons. Don't think he was really a deacon either.

I believe he eventually died on the gallows he designed which had a trapdoor so that the victim died of a broken neck, not by strangulation.

Cheers,
Alan
