They share a secret - every night, when their parents think they are asleep, they sell matches and shoelaces on the streets of Berlin with Dot's grumpy governess. But why?The answers involve a villain called 'Robert the Devil', a club-wielding maid, a wobbly tooth, a pair of silver shoes and a policeman dancing the tango, as Dot and Anton get into all sorts of scrapes and even solve a crime in this delightful, touching and hilarious adventure story.
