Mr Boyle is a character in the Understone DLC in Fable III. He is the quest-giver for The Voice. He recently purchased a factory, but nobody will work there due to it being "haunted": a disembodied voice is emanating from the bowels of the factory. Mr Boyle hires the Hero to investigate the basement, where the voice is coming from. Instead, deep in the caverns beneath Bowerstone, the Hero discovers Understone, an underground community created over fifty years earlier by the rich, eccentric inventor Montague Humes, who directs the daily lives of the citizens by relaying messages over a loudspeaker system.
