A book of manners, magic and mayhem!

After Edward and Jemima's honeymoon is cut short by a severed head landing in their marriage bed, they must away to London to devise a way to defeat the ravenous beast, Geneck, and Jemima must be the bait.
Newspaper headlines reveal carnage in London streets and the police and the secret brotherhood of magicians are pounding at the door, demanding answers from Edward.

Joined by Fulton, Edward and Jemima begin to scour the dark places of London: sewers and newly-constructed underground railway tunnels. Their only chance is to find Geneck's lair and end him in daylight, when he is weak. But the monster's minions protect him and the road to safety is not clear.

When Jemima is taken, Edward is beside himself. Who has taken her and how is he going to get her back? Deeper into magic he must go, and Milly and Aunt Prudence join in the fight to rid the world of Geneck. But will that be enough?
