The cheer of the holidays may have passed, but the Noah's Ark traveling circus has been making the rounds, bringing fun and joy to children of all ages. However, as the ringmaster's cries fade away, a disturbing trend begins to surface in the wake of the colourful entourage. Children are disappearing whenever the circus packs up for its next destination, and there are no clues - or corpses - to be found.

Dismayed by these occurrences, Queen Victoria dispatches Earl Phantomhive and his most able butler, Sebastian, to locate and reunite the missing children with their loved ones. When the situation calls for the pair to infiltrate the big top undercover, however, will Sebastian's inhuman skills be enough to see him and his young master through a treacherous tightrope act that may well end in death?

Having successfully infiltrated the Noah's Ark Circus in the guise of rookie performers, Earl Ciel Phantomhive and his butler, Sebastian, set about gathering clues backstage as to the whereabouts of the missing children. But when a turn at a snooping puts Ciel on the trail of a man whose identity is shrouded in mystery, he sets his consummate manservant to the task of investigating further.

This time, however, Sebastian must call upon one of the more infamously wicked skills of his kind to solve the puzzle. As he stalks his vulnerable prey in the shadows of the fairgrounds, is his young master prepared for where the ill-gotten gains of his butler's methods will lead?

When one curtain falls upon the big top stage, another rises behind the scenes, as young Earl Ciel Phantomhive and his virtuoso butler, Sebastian, face off against the villain behind the missing children.

With the masterless Phantomhive Manor under attack from the Noah's Ark Circus and Sebastian nowhere nearby to protect its inhabitants, is Ciel's home once again headed for the same tragedy that took the lives of the young earl's parents?

Earl Ciel Phantomhive's quietude following the conclusion of the case of Noah's Ark Circus is short-lived, as Queen Victoria's very own butlers commandeer Phantomhive Manor and all its residents for a lavish banquet sanctioned by Her Majesty. Preparations for such an event are quick work in the hands of Sebastian, the house's most able butler, but corralling eminent guests during his young master's first-ever attempt at playing host may prove to be rather more of a challenge.

This dinner party is anything but festive, and as a stormy night batters the outside of the grand residence, a far more violent storm begins to unfurl within the confines of the manor. And no one is safe from the havoc it will wreak - not even one seemingly impervious manservant...

With his royally sanctioned dinner party a shambles and a murderer on the loose, Earl Ciel Phantomhive is a veritable prisoner in his own home, alongside those of his guests who still live. And in the most shocking of turns, the young earl now finds himself without his indispensable manservant, Sebastian.

But as the mystery deepens, there arrives upon the young earl's doorstep an odd vicar, wearing an insolent smile and an Inverness cape that flaps and splashes behind him... Is this mysterious thirteenth guest the perpetrator of the crimes that have bloodied the halls of Phantomhive Manor?
