Garner's observations of how Harrison uses Isaac in the Berlin darkroom - the implicit dismissal of consent and overblown justification of gay liberation, are all devastatingly delivered. The writing is very subtle but the juxtaposition of Isaac's inner voice and Harrison's outer one is really powerful - there are emotional lines that most people find too complex to understand in their lives, but it's here in Garner's writing. I hope Isaac and Cherish make up.
