The heroine of this fascinating story (described only as 'I') is compelled to visit a mysterious uncle, a black magician who lords over a kind of Prospero's island that exists out of time and space. Startled by his bizarre behaviour and odd nocturnal movements, she eventually learns that he is searching for the philosopher's stone. When his sinister attentions fall upon the priceless jewel heirloom in her possession, bewilderment turns to stark terror. She realizes she must find a way off the island … Goose of Hermogenes is an esoteric dreamworld fantasy composed of uncorrelated scenes and imagery mostly derived from medieval occult sources. That will repay several readings. Each chapter title in the book has a title relevant to a stage in alchemical progressions. However one wants to approach this obscure tale, it remains today as vividly unforgettable and disturbing as when it was first published by Peter Owen in 1961.
