Yes, I read The Daughter of Time, oh, I think most likely back in the nineteen fifties. I read and loved ALL of Josephine Tey's books and she is right up there on the very top of my list of the finest mystery writers. I had read Thomas Costain's The Last Plantagenets (now, was that 3 books in a boxed set, or 4? I have passed them on to a granddaughter, and my memory is now shaky on such details, whereas once I could have immediately told you every title and the years each book covered!), and HE wrote like an angel and I fell in love with that royal family, so that latest, and I believe last, of Tey's books delighted me no end. And yes, I tend to believe the Tudors lied through their teeth in order, through propaganda, to cement their quite illegitimate claims to the throne. Of course, Henry VIII could claim through his mother, if she was indeed the last living. Who knows? But Henry VII? I don't think so. When I went to London, I followed Josephine Tey's advice and went to the National Portrait Gallery and LO! At that time, they had Richard 3 and Henry 7 right next to one another. And she was right. If you asked yourself which man you would trust with your children, you would pick Richard every time. Hey Steph, there's something to put on your list while in the Smoke.
By the way, there are a number of other books out which support Richard's side of things. I would give you a list, but again, I have passed them on to Paige, who teaches High School history classes in an all girl's school in Baltimore.
