The Vienna of lovely pastries and charming buildings and old gardens is delightfully recaptured in this story of little quadruplets who have an infinite capacity for getting in and out of mischief. Maxel and Poldi, Ferdel and Lisel, three boys and a girl, are fourfold fun and warmth and reward to their family. No attempt has been made to revamp the book for its American audience. Like Emil and the Detectives, the foreign air is a large part of the charm. There is a birthday cake too, not four cakes, a mind you, a wonderful one with forty candles. The plot is jolly, so sustained that there is not a dull page.
