According to The Gaurdian, "To Kill A Mockingbird" author Harper Lee just might be releasing another new book. The Wall Street Journal exclusively published the first chapter to Lee's new book, "Go Set A Watchman," on Friday and also quoted Lee's lawyer, Tonja Carter, as saying Lee might have a third book she's written yet never released.

As was previously reported in the New York Times, Carter found the "Go Set A Watchman" manuscript in Lee's safe deposit box, and just last week said the box held other surprises: "What we found was extraordinary and surprised even me,” she says in the Wall Street Journal.

Carter says she isn't sure if the manuscript she found was an old draft of "To Kill A Mockingbird" or another book tied to it and "Go Set A Watchman." Everything is still being evaluated. Lee, for her part, has not commented on it at all.

"Go Set A Watchman" is out tomorrow.
