 Raven's book of anecdotes and reminiscences, "Is there anybody there?said the Traveller" (Frederick Muller 1990) was withdrawn after a series of libel threats, including a writ from his former publisher Anthony Blond.Thereafter he planned, or at least threatened, to write a new work "All Safely Dead", in which, safe from the laws of libel, he could "expose" various deceased luminaries from the British social, academic, political and literary scenes, but the book was never written.
