As for that part, blackwood bribed the executive. When he hanged himself, he tied an iron hook to the drawstring, that is, tied it together and hooked it to the collar of Wood's suit, so that he wouldn't strangle him. In fact, the rope around his neck was just for show. It was worn on his head and didn't straighten at all, creating an illusion. As you can see, the iron hook has three small bends and a small hook (tie).

Hope to adopt
