Radcliffe by David Storey (1963)
Like "Brokeback mountain" except it is longer and quite well written.
According to one review:
It is a Gothic novel in which a metaphyical dimension to the spiritual horror develops out of the
novel's uncanny correspondence with "The Idiot". Radcliffe easily brings to mind
Dostoyevsky; it has the the elements – the drama of a split psyche; larger-than-life
characters; sadism, masochism, rape; incest, murder, and madness; a focus on isolated
suffering through dreams and hallucinations......
Very dark and with a very tragic ending.
