In this second, welcome book about the triplets, Abercrombie, Benjamin and Christopher, the boys- in unison and in part- chorus through the week prior to Centerville's fair and the fair itself. It is their ambition to win a prize in the livestock show. To enter, they must work in the town, to earn the money, to buy the calf, to come from the cow called Maggie Moo- old, fat and crooked horned, who belongs to Farmer Finney. This they do- at home, at the store, on the farm. But at the last moment, Farmer Finney's prize cow, Queen Liz, gets a cold and Maggie Moo must be sole representative. She wins because she is all of a remarkable seventeen years old and has triplet calves on the eve of victory. There is a rhythm in the skillful playing of the bovine moo and and sway against the rougher, cow-geared, fair geared rompings of the boys that will bring clamours for rereadings, and Marian Honigman's sharply defined drawings are farmy as can be.
