Gun in Cheek : An Affectionate Guide to the Worst in Mystery Fiction
by Bill Pronzini
Love mystery? Then you'll love this book. Hate mystery? Then YOU'LL love this book. Pronzini is a fount of information about the "best" (read: hilariously inept) in mystery fiction. He's read every book ever written in the genre, it seems, and shows genuine affection for the form.
