When scoping the cuties at Van Pelt turns up, well, no cuties, pull your top hat low, trench coat tight, and head down to Whodunit - Philly's only mystery bookstore - to brush up on your detective work.
Around since 1976, Whodunit's shelves are stuffed with everything you need to get back in the game as a more suave and discerning incarnation of your former self: volumes upon volumes of Sherlock Holmes and The Hardy Boys.
