Black Butler, Vol. 2 (黒執事 [Kuroshitsuji] #2)

As high society's social calendar opens up and the Season draws to a
close, London is gripped by fear. Someone has taken to stalking women
of the night and painting the town red...in their blood. The name on
everyone's lips seems to be "Jack the Ripper" - and as a result, the
name on Queen Victoria's lips is Phantomhive. Summoned to London to
clean up the mess created by this madman, Ciel Phantomhive arrives with
Sebastian, his extraordinary butler, at his side to pour him tea,
polish his silver, and...investigate a serial killer. And with the aid
(and occasional interference) of a few of the Phantomhive house's
numerous acquaintances, little stands in the way of the young earl
getting to the bottom of this mystery. However, one question
remains...can he handle the shattering truth behind it?
