No obviously not.
If I had I would not have asked the question. One of them I know the other I don't. They are both peers of the realm.
Both Peers have in their homes evidence that Francis Bacon, an Elizabethan, was Shakespeare, which forms part of my novel.
I have been a guest of one peer on several occasions many years ago but who is now a recluse and un-contactable, although I know the features of his Elizabethan home which I have described in my book (it is not open to the public) and have described a fictional dinner party with a fictional dinner guest who is the heroine of my story. I have not had the peer say any words but have described him in complimentary words as well as some description of his home.
The other peer is well known to a good lady friend of mine who has said I should write to him. Her now dead husband was born in the same stately home which is open to the public and well known. I have put a few words in his mouth in which he greets the heroine of my story and helps her find the evidence she looks for. I also have my heroine have a few pleasant words of exchange with the peers wife.
I would imagine your reply will be to try to make contact with them and to show them my wording, and the context of my story, but before I do so I would like to know my position in law.
Thank you. It was unexpectedly helpful. I did not ask the question in relation to US law where the book may be published but seeing US laws of libel etc are less stringent than the UK I will assume that I would get the same answer as yours from a US lawyer.
