My recommendation comes rather late, but if you are based in London and interested in the relationship between Thomas Hardy and his wives I can recommend the play What I Think of My Husband by David Pinner, running at the Grey Goose Theatre in Camberwell until Saturday, 2nd December.
You can find fuller details at the theatre's website (link at end), but for those who are unfamiliar with the story the essential facts are that the writer Thomas Hardy's marriage to his first wife Emma soured over time, with the couple eventually living largely separate lives under the same roof, but an outpouring of grief and guilt after Emma's death led to a sequence entitled Poems of 1912-13, generally agreed to be his best work in that form.
