Is Edmund Morris writing a final autobiography for Theodore Roosevelt; to follow the first two already done?

Question

Edmund Morris has written "The Rise of Theodore Roosevelt" covering Teddy's life up to when he first becomes President and "Theodore Rex" which details Teddy's time as President.

I was under the impression that Mr. Morris was going to write a final book which would finish Teddy's life.

Answer 1

As far as I know, he still is. These biographies take years and years to write. Robert Caro has taken most of his life to write a book on Robert Moses and four books (last one on the way) on Lyndon Johnson.

Mr. Morris will get there eventually.
