Which do you prefer between those 2 absolute best crime and mystery authors? I have no preference at all personally for either of them. Currently binge-reading on my "Amazon Kindle" : "The Murder of Roger Ackroyd" by Agatha Christie and totally engrossed and thrilled by it. They never have dissappointed me in any way. These 2 British authors of crime and mystery I highly recommend to anyone who's a fan of these 2 genres.
