As you have two books of mine, of which one, at least, I understand is to be published in October, I am writing to explain that, if in prison, I shall not be able to correct the proofs ... I enclose a statement to be published, if I am in prison, but not otherwise." The statement could preface either or both of his two forthcoming books.
