Dear Mr Cornwell I enjoy your books tremendously and find them not only a thoroughly enjoyable read and interesting from the military history point of view. I wonder if you have ever considered a series about Mehmet the Conqueror, an intensely interesting man who virtually kick-started the Renaissance by capturing Constantinople. I have never seen anything about this man other than history though he had an immense impact on Eastern Europe, the Mediterranean and the Middle East. Not only that there were his enemies such as Georg Skanderberg and Jan Hunyadi and perhaps a very young Vlad Tepes. These are real people who, like your characters, were very interesting from the stand point of history and of character. Though since you have so many series going one more may not be possible.
