Complete Monster: The sinister John Gray, "evil himself", is a cabman by day and a grave robber by night. Gray digs up cadavers to provide to his associate, Dr. "Toddy" MacFarlane, and he shows off the kind of man he is by braining a dog with his shovel when it almost gives him away. Eventually, taking inspiration from the old case of Burke and Hare, Gray murders a harmless, blind street singer to give her corpse to MacFarlane. When Gray's assistant Joseph tries to blackmail him, Gray laughs, smothers him to death, and presents his body to "Toddy" as a sick gift. Gray finally admits he puts MacFarlane through such psychological torture just for the pleasure of having a rich man bent to his whims, and he vows he'll never stop tormenting MacFarlane. Gray haunts MacFarlane even past his own death, having broken the doctor beyond the point of all recovery, and his words follow MacFarlane to his untimely death: "you'll never be rid of me, Toddy!"
Ho Yay: Gray's obsession with MacFarlane has him try to be an all-encompassing, all controlling figure in Gray's life, and he seems unable to settle on either being MacFarlane's tormentor or his friend. Plus MacFarlane's embarrassment over their history together sounds like a shameful past relationship.
