Blurb

When the Queen of England gives her pet guard dog a new mission, one does not simply give up.

"After all, what kind of butler would I be if I couldn't solve a mystery with my master?"

"I wouldn't simply be one hell of a butler, now would I?"

Join Ciel, Sebastian and the gang as they travel the world, trying to discover just why exactly it seems that the population of each country is counting down at the same time; in practically the same places. A book of thriller, and a book of mystery;

A book of horror, if you please.

"What kind of butler would I be...

...without my master?"
