Open for business since 1994, WHODUNIT was bought in 2007 by loyal customers Jack and Wendy Bumsted. WHODUNIT is Winnipeg's specialty mystery bookstore, offering a full range of crime fiction.. The bookstore hosts a Mystery Reading Club and has readings and signings by mystery authors.

WHODUNIT has become a family affair, with son Michael as award-winning bookseller (Chase Paymentech Young Bookseller of the Year, 2013) and daughter Sian as social media and general internet guru. 

WHODUNIT carries both new and used books and can special-order any book that is commercially available, as well as ship to out of town customers, accept pre-orders for Winnipeg-based customers, and deliver to those unable to reach the bookstore themselves.
