As readers of Mark Haddon's

The Curious Incident of the Dog in the Night-time know, this widely lauded debut novel opens with Christopher, a high-functioning autistic teen, discovering a murdered poodle on his neighbor's front lawn. Now the bestselling Doubleday hardcover—nine weeks on PW's list, with 200,000 copies sold—has been released as a Vintage trade paperback, and a new audience can discover the unique work that was a New York Times Notable Book, won the Los Angeles Times Book Prize, was named Whitbread Best Book of the Year and was a Today Show Book Club selection. After four trips back to press, Vintage reports 255,000 copies in print. Senior publicist Sloane Crosley told PW that Haddon (like Green, another Brit) "is braving a pretty major fear of flying to cross the Pond" to undertake an East Coast tour this week (by train) that will range from Chapel Hill, N.C., to Boston.
