Sorry, I should have made it more clear that I was referring to the request for proof of the claim for the “BTW, she never wrote anything else part.
There is no proving that negative. If you only meant proof of the Truman Capote wrote TKAM claim, I don’t think that is something that will ever be proven beyond a shadow of a doubt one way or the other. But if we’re talking proof that “BTW, she never wrote anything else, there is no proving it.
