I read this at the weekend in New York magazine, and I was open-mouthed for most of it. It’s a story that starts bad, gets worse and then goes rapidly downhill from there.

On March 7, 2015, Harvard Law professor Bruce Hay, then 52, was in Tags Hardware in Cambridge, Massachusetts, near his home, when a young woman with long reddish-brown hair approached him to ask where she could find batteries. It was still very much winter, and, once the woman got his attention, he saw that underneath her dark woolen coat and perfectly tied scarf she was wearing a dress and a chic pair of boots — hardly typical weekend-errand attire in the New England college town. When he directed her to another part of the store, she changed the subject. “By the way, you’re very attractive,” he remembers her saying.

I don’t want to give anything away. You’ll read it from behind your fingers.
