'Clive Broderick, guitar-teacher and occultist - the Doubleman of the title of this acclaimed novel - is speaking of power, and of a realm beyond reality. This is a fable of the sixties, when shared belief-systems crumbled, and the spiritual bazaars of today opened up. Christopher Koch's theme is illusion; and all his characters are bound by it. The Rymers are an electric folk group enjoying mounting success in Sydney. Their producer, Richard Miller, came under Broderick's spell during his youth in Tasmania; so did the guitarists Brady and Burr. Now, years after his death, Broderick's presence remains with all three. Through his disciple, Burr, it will lead to nightmare.'
