The Swimming-Pool Library — Alan Hollinghurst

Young, gay, William Beckwith spends his time, and his trust fund, idly cruising London for erotic encounters. When he saves the life of an elderly man in a public convenience an unlikely job opportunity presents itself - the man, Lord Nantwich, is seeking a biographer. Will agrees to take a look at Nantwich's diaries. But in the story he unravels, a tragedy of twentieth-century gay repression, lurk bitter truths about Will's own privileged existence.
