      This brief pamphlet outlines some of the simple permutation and
      substitution ciphers that have been used over time. The emphasis is
      on the clever little tricks that go into making ciphers slightly
      harder to crack. None of the algorithms are terribly sophisticated,
      and exercises are given at the end of each chapter. Instructions are
      given for decrypting some of the ciphers, even if you don't know the
      key.

      Two additional chapters address related topics. The first deals with
      various forms of secret writing, such as invisible inks, or
      steganographic messages. The last chapter briefly examines the
      problem of creating messages that unknown people, with unknown
      languages, may be able to solve (such as sending messages to the
      stars).

      None of the material is strenuous, but this may be a nice start before
      moving on to a work such as Gaines "Cryptanalysis" (cf. BKCRPTAN.RVW).

      [In the Anglican Church] whether or not one believes in God tends
      to be sidestepped. It's not quite in good taste. Someone said
      that the Church of England is so constituted that its members can
      really believe anything at all, but of course almost none of them
      do. - Alan Bennett
