"Excuse Me, Do You Have Any Books About Jeffrey Dahmer?"

Now there's a question bookstore clerks probably don't like to answer. Tonight I overheard a homeless man ask this of a very kind Barnes & Noble employee. He was directed to the nearby True Crime section.

Many creepy characters frequent this massive five-story B&N branch near Lincoln Center, which is open until midnight every day. The store has a homeless population that may reach the three digits. I once observed a disturbed man coming down the escalator singsongingly shouting over and over to no one in particular: "I'm shocked to see you. I thought you died long ago." Nightmare inducing, I'll tell you.
