His Butler, in an Isolated Castle

Ciel is informed that the abandoned Ludlow Castle that his estate owns is haunted by ghosts and the workers are too spooked to continue remodeling it into a hotel, so he and Sebastian head to the castle to investigate. There they encounter the ghosts of two princes who were assassinated four centuries ago, Edward V and his brother, Richard. Ciel plays a game of chess against Edward V to pass the night, but he loses and Edward claims Sebastian as his winnings. Alone, Ciel solves the mystery behind the princes. The ghosts of Edward V and Richard thank Ciel and Sebastian before departing for the afterlife, and the remodeling of Ludlow Castle resumes.
