A man who made one of the last trips by windjammer around Cape Horn in 1948 has sold his story to Philip Turner at Carroll & Graf.

Harper executive editor Dan Menaker bought a book by Los Angeles Times reporter Sonia Nazaro for the house's Spanish-oriented Rayo imprint.

The editor got world Spanish and North American English rights from Coast agent Bonnie Nadell.... A Harper first novel called Boy Still Missing by John Searles has been optioned as a potential movie by Broadway producer Daryl Roth for her movie-making debut; the deal was made by Hollywood-based agent Joanna Pulcini.... A provocatively titled children's book, Walter the Farting Dog, proved such a strong seller for publisher North Atlantic Books (120,000 currently out there) that Dutton Children's Books publisher Stephanie Owens Lurie upped for two more from Walter's creators, authors William Kotzwinkle and Glenn Murray, with illustrator Audrey Colman. The world rights deal was made with agent Jennifer Carlson at Dunow & Carlson, with the first of the new books out next year.
