Black and Littlejack are bad men. Littlejack has a map that indicates the existence of a treasure on a far and lonely island. He needs a ship to get there. Black has a ship. So they team up and sail off on Black's vessel, the <i>Aeiu</i>. “A weird uncanny name,” remarks Littlejack, “like a nightbird screaming.” Black explains that it's all the vowels except for O. O he hates since his mother got wedged in a porthole. They couldn't pull her in so they had to push her out.<br><br>Black and Littlejack arrive at the port of the far and lonely island and demand the treasure. No one knows anything about it, so they have their henchmen ransack the place—to no avail. But Black has a better idea: he will take over the island and he will purge it of O.<br><br>The vicissitudes visited on the islanders by Black and Littlejack, the harsh limits of a life sans O (where shoe is she and woe is we), and how finally with a little luck and lots of pluck the islanders shake off their tyrannical interlopers and discover the true treasure for themselves (Oh yes—and get back their O's)—these are only some of the surprises that await readers of James Thurber's timelessly zany fairy tale about two louts who try to lock up the language—and lose.
