Dear Mr. Cornwell,
I reorganized my bookshelf this morning, and counted 17 of your books on the shelf! I am writing mainly to express my immense appreciation for the pleasure I have gotten from multiple readings of these books.
I am a retiired industrial research chemist (43 years with Procter & Gamble) and I have one book of my own (on physical chemistry). I am learning more about history by reading your books; this has become one of my principle avocations.
Being a professional researcher has made me conscious of the level of accuracy in the things I read. History books from an earlier day do not have a terribly good record in this regard; they are often biassed and inaccurate. But one of the reasons I have so many of yours is that they all stand up remarkably well in this regard. Now, one can check such matters by reference to Wickipedia articles on the subject, and I congratulate you on your attention to such matters. You rank with David McCullough here; I have a high regard for him also.
So thanks, again..
Robert G. Laughlin
