"Angelica's Grotto" is a pornographic website into which seventy-two-year-old art historian Harold Klein wanders one evening. Klein, a walking catalogue of infirmities, may not be up to much physically but there's a lot of sex going on in his head.
Harold Klein's odyssey takes him not only through the erogenous zones of the web, but into various corners of the London art world, down the Underground and up the buses.
