Book excerpt: A man wearing his wife's fur coat and a woolly balaclava is chained to a kennel in the backyard whilst another man delivers a side of bacon to The Devil. Fish trained to walk, devils in the stove, cats carrying coffins, ogres with a taste for fat little boys and beetles that do the housework - and then there's the small matter of teaching a calf to talk. Thirty-eight folk and wonder tales from Denmark from Svend Grundtvig and his collectors.
