Whodunit Books is another gem of a bookstore in Philadelphia. Just off Rittenhouse Square at 1931 Chestnut Street, the store has a variety of used books, with an emphasis on mysteries. With a cellar-like environment, it’s Poe-ishly welcoming. (BYO amontillado.)
Although the hours are listed only until 6:30 p.m., I’ve been in there later. (These photos were taken close to 8 p.m.)
It’s a must visit.
