Dear Bernard
You probably get tired of people making suggestions about who to write about, but what about T E Lawrence?
There are many (history) books written about him, but no novels as far as i know I suppose the tricky part of writing that sort of story is that SO MUCH has been written about his life that it might be difficult to create a narrative that did not read like a history book!
Also, there are many fans of his that might be irritated by you playing fast and loose with their hero.
Hope you are keeping well in these trying times
Best Wishes
John B
