For as many mysteries as I read, I would have thought I'd have done better than this. I guess I have a little work ahead of me, though some of these titles I will have to pass on. Of course the list is almost fifteen years old now. I wonder what it would look like if they made a new list with all the excellent crime fiction that has been published in the interim!
