Thom Gunn's The Man with Night Sweats shows him writing at the height of his powers, equally in command of classical forms and of looser, more colloquial measures, and ready to address a wide range of themes, both intimate and social. The book ends with a set of poems about the deaths of friends from AIDS. With their unflinching directness, compassion and grace, they are among the most moving statements yet to have been provoked by the disease.
