A little over 50 years ago, in the last days of a summer something like this one, a woman returned home from her publishing job to find a literal bloody mess. She shared the apartment on East 88th St between Madison and Park with two other young women in their early 20s. She took a few steps into the living room and saw a knife perched on the edge of the bathroom sink. Then she called one roommate's father, Max Wylie, who lived nearby, and ventured no further.
