The Mad Man
Samuel R. Delany
 In New York City in the early 1980s, John Marr, a black gay graduate student, is researching a dissertation on Timothy Hasler, a Korean-American philosopher and academic stabbed to death under unexplained circumstances outside a gay bar in 1973. As details emerge, Marr finds his lifestyle converging with that of Hasler, and he becomes increasingly involved in intense sexual encounters with homeless men, despite his growing awareness of the risks of HIV.
