" Suddenly he recalled long-forgotten words, lines from a poem—Donne, wasn’t it? Who is as safe as we where none can do / Treason to us, except one of we two. Even when he was warmed by her naked flesh, treason slithered like a snake into his mind and lay there heavily coiled, somnolent but unshiftable. "
― P.D. James , The Lighthouse (Adam Dalgliesh #13)
