New York’s Mysterious Bookshop

The world’s oldest and biggest bookstore focusing only on mystery, crime fiction, espionage, and thrillers is owned by Otto Penzler. The bookshop’s door is roped off with a big X made of yellow police tape reading CRIME SCENE DO NOT CROSS.
Down a flight of stairs, the owner’s office is a low-ceiling basement cube with floor-to-ceiling bookshelves on all four sides, stocked with anthologies and first editions as well as a random sampling of mass-market hardcovers and paperbacks. If the office was a store by itself, it would be the second-best mystery bookstore in the world.
