President Bush's first press secretary, Ari Fleischer, is writing a memoir about his time at the White House, and Claire Wachtel at Morrow has acquired it for what published reports said was about half a million dollars. She bought world rights from agent Bob Barnett at Williams and Wilkins, and plans to publish the book, which is untitled as yet, early in 2005. Fleischer spent four years with Bush as Texas governor, then president, before leaving in July to write his book.
