When the Great Raven steals their Mothers precious brooch the Twins Henry & Henrietta are blamed & told that unless the brooch is returned their Birthday Party in four days time will be cancelled & that their four Animals Curd the Lion Pilgrim Crow Sweeney the Heenie (a hyena) & OFlattery the Snake will be given away to the Charity Shop. Curd the Lion who witnessed the theft leads the Animals out that night all the way to the Back of Beyond to find the Great Raven & try to rescue the brooch. Meeting first that unfathomable inflatable Professor Balloonafuss creatures they encounter include His Majesty King Much of a Muchness Nook & Cranny Queen Mumbie-Bumbee & the Dodongs. By the time they enter Holywood with its Minor-Bore knightly Sir Rush & his Kalandar their route has become so riddled with pitfalls & the talk of the beasts so twisted the Animals can hardly tell whether they are coming or going. Reaching at last the Rocks of Brimstone & the out-jutting Corbie-stone lair of the Great Raven the Animals discover both friends & foes converging on this pivotal rock. A great battle ensues. The author has included the first three chapters of a second adventure The Ineffable Emperor or Travels in the Land of Nod in the Great Sea of Slumber as an invitation to readers to ask for more. No illustrations (though there will be of course in the real book)
