Sir Geoffrey Hawkes was a landowner before he fell into the sway of Evelyn Poole. She needed him to exert pressure on Joan Clayton in order to claim The Poetry of Death, a cursed book in Clayton's home. To that end, Hawkes was seduced by Evelyn and persuaded to do all he could to buy out her property, or force Joan to leave. Part of this also included a campaign of harassment against the old Cut-Wife of Ballentree Moor.
When efforts to force Clayton out failed, Evelyn goaded Sir Geoffrey and a handful of townsfolk into taking action. Sir Geoffrey then led a lynch mob to Ballentree Moor and called Clayton outside. They bound her, and doused her in oil before setting her alight, and then turned on her ward Vanessa Ives, whom they branded with a hot branding iron in the middle of her back before departing.
Five years later, Sir Geoffrey chanced upon Miss Ives and Ethan Chandler as they were out walking in the woods. He made lurid comments, and threatened the pair with his pack of dogs, before spurring his horse and departing. Later at night he went out to feed his dogs, unaware that Vanessa had opened The Poetry of Death, and was driving them into a rabid fury from afar. The dogs turned on Hawkes and mauled him to death.
- Sir Hawkes' death is possibly a homage to Dario Argento's classic horror film Suspiria, where a witch casts a spell on a blind man's guide dog to make it attack and kill its owner.
