Kuroshitsuji: Book of Murder

At Queen Victoria's command, Ciel Phantomhive hosts a lavish dinner attended by aristocrats, professionals, and the struggling writer Arthur. A violent storm traps everyone inside the manor, where a guest is murdered and evidence points toward Ciel himself.

More deaths follow despite Sebastian's seemingly perfect control of the household. With no one able to leave and every guest hiding something, Arthur is drawn into an elaborate locked-room mystery whose solution may be more carefully arranged than the crimes.
