The Best American Mystery Stories by Otto Penzler

The Best American series is the premier annual showcase for the country’s finest short fiction and nonfiction. Each volume’s series editor selects notable works from hundreds of magazines, journals, and websites. A special guest editor, a leading writer in the field, then chooses the best twenty or so pieces to publish. This unique system has made the Best American series the most respected—and most popular—of its kind.
