Join the wonderfully weird Otherhand family and their faithful guardian, Edgar the raven, and discover the dark secrets of Castle Otherhand.

Solstice and Cudweed are appalled to find their father has appointed a new school master. But things get even worse when the grumpy, viciously mean teacher actually arrives. The Otherhand children are sure there's something more to him than meets the eye - the trouble is, who will believe them? No one it seems. Except, perhaps, Edgar.

Winner of the 2011 Blue Peter Book Award for Most Fun Story With Pictures, LUNATICS AND LUCK is the third story in this hilarious six book mystery series (with a touch of goth-froth) for 9 year olds from bestselling author, Marcus Sedgwick with quirky black and white line illustrations from new talent, Pete Williamson.
