What is “noir” in fiction? Makes me think of Garrison Keillor’s private eye Guy Noir. But apparently the answer is very broad, given the scope of stories in “Boston Noir 2: The Classics” (Akashic Books). Authors include David Foster Wallace, Joyce Carol Oates, Andre Dubus and others (the group that includes me). My story “The 5:22,” which I wrote in 1999 and was chosen for Best American Short Stories that year, was picked for its Twilight Zone feel. In reviewing the anthology the Boston Globe described “The 5:22” as “like a ghost story…with a delightful twist.” That’s a take on it I hadn’t heard before.
