Step into a London lit up by the Elemental spirits: the fiery Dragons, the airy Fumis, the watery Chads and the earthbound Magogs. Marisee and Robert - the Elemental Detectives - are back to solve another mystery on the streets of eighteenth century London. An orchestra explodes in Vauxhall Pleasure Gardens and suddenly the music of London disappears...

and a terrifying monster stirs off the Greenwich peninsular, threatening to trample London underfoot. The detectives must track down the thief behind the music's disappearance - via the Whispering Gallery of St Paul's Cathedral, a Windmill-with-teeth on the Isle of Dogs and the dark streets of Soho... where a shadowy villain and his mechanical animal spies live.

Big, bold, future classic storytelling for a new generation. A London where magic sparks just beneath the surface - this book is set to ignite young imaginations.
