Valerie Wilson, the former Central Intelligence Agency officer whose identity was publicly disclosed three years ago, has agreed to sell her memoir for a little more than $2.5 million, according to people involved in the bidding process for the book.

The book, whose working title is "Fair Game," is scheduled to be published in the fall of 2007 by Crown Publishing, an imprint of Random House. Steve Ross, senior vice president and publisher of Crown, said the book would be Ms. Wilson's "first airing of her actual role in the American intelligence community, as well as the prominence of her role in the lead-up to the war."

Ms. Wilson, he added, "has been this mysterious woman at the very eye of a major storm, and the concentric circles keep widening."

Ms. Wilson's name first appeared in a column by Robert D. Novak, the syndicated columnist, in 2003, spawning a full-scale Washington scandal that ensnared several government officials and journalists. The special prosecutor assigned to the leak case, Patrick J. Fitzgerald, has already brought perjury and obstruction of justice charges against I. Lewis Libby, the former chief of staff for Vice President Dick Cheney, stemming from his investigation, and the inquiry continues. Karl Rove, the presidential adviser, recently testified before the grand jury in the case.
