He is a brilliant writer, absolutely the best researcher I think, incredible attention to detail. Astonishing stuff. I love his books. I wish he would write a book about the Romanovs, he is sure to unearth things we have never heard of. He has a habit of finding things ( all indexed and referenced) that other writers dont. But I think so much has been written about the last family that most biographers and historians view the subject with a jaundiced eye. Have you read his book on Catherine ll ?
