Koch could seem as though he was scrambling to fill every hour with bustle. He dragged friends to the movies, dabbling in freelance film criticism.

Koch described to a few friends a feeling he could not shake: a deep loneliness. He wanted to meet someone, he said. Did they know anyone who might be “partner material?” Someone “a little younger than me?” Someone to make up for lost time? “I want a boyfriend,” he said to one friend, Charles Kaiser.
