A thing about which I am totally ignorant, and re which I would be grateful for info, from those in a position to know more than I do.
Two people who have received prison sentences, for an offence in which both of them were involved, and for which they were sent to separate-and-different prisons: would they, while imprisoned, be able to write (snail-mail) letters to each other? Obviously, any such letters would be subject to censorship by the prison authorities; but, that being accepted, would such a correspondence be allowed to happen?
I would say that I am in the UK; and am contemplating attempting a work of fiction, in which such an exchange of letters would be a plot point – and also, action of said work, would be in the World War I era, set in the UK. Concerning this matter, I’d imagine – perhaps wrongly – that such things, now as a hundred years ago, would not be / have been, immensely different between the UK, and North America. I’d be grateful for any input from knowledgeable persons, on this issue.
