You should read the whole story at the blog home of The Outfit, a group home for wayward Chicago mystery writers, including Guilfoile, Sean Chercover (who I still need to start reading), Libby Fischer Hellmann, and David Ellis (a neighborhood kid I knew growing up, who's gone on to great things prosecutorial and authorial).
