Still shocking

"In the days when answerphones were machines that contained twin cassette decks, one for outgoing messages and the other for incoming I pushed the envelope a bit. I wrote a novel that consisted of chapters that when spoken would fit onto the 30 seconds of the outgoing tape. I created new episodes weekly. My phone line was jammed with fans ringing in to hear the next episode."
