Gadsby is a 1939 novel by Ernest Vincent Wright which does not include any words that contain the letter E, the most common letter in English. A work that deliberately avoids certain letters is known as a lipogram. The plot revolves around the dying fictional city of Branton Hills, which is revitalized as a result of the efforts of protagonist John Gadsby and a youth organizer. Though vanity published and little noticed in its time, the book has since become a favorite of fans of constrained writing and is a sought-after rarity among some book collectors. The first edition carries on title page and cover the subtitle A Story of Over 50,000 Words Without Using the Letter "E" (with the variant 50,000 Word Novel Without the Letter "E" on the dust jacket), sometimes dropped from late reprints. Despite Wright's claim, the work accidentally contains four uses of the letter "e": "the" three times and "officers" once. Source: Wikipedia (en)
