At the Queen’s request, Ciel and the demon butler Sebastian host an extravagant dinner party for the who’s who of the London underground. But an evening that begins with the promise of unmatched elegance quickly spirals into mayhem when their most distinguished guest is found murdered in his room. Now, trapped in the Phantomhive Manor by a dark and stormy night, Ciel and Sebastian must work together with their high-class guests, including the legendary author Sir Arthur Conan Doyle, to find the murderer in their midst before the blame falls on the host and his somewhat suspicious staff.

Ciel learns of a "Aurora Society", that is rumored to be researching how to bring the dead back to life. Their next meeting is scheduled to be conducted on the ship Campania, voyaging across the Atlantic Ocean. Much to Ciel's dismay, Elizabeth "Lizzy" Midford, is taking the same ship, thus leaving him with no choice but to get aboard as well.
