I was asked the following question by email a couple of days ago. I won’t include the name of the person asking in case he doesn’t want it circulating online without his knowing about it, but I thought it interesting enough to see how others besides myself might answer it:

    “I am a fan of old, rare books and I wonder if there is any mystery/crime/horror/suspense not widely known book from the past decades that hasn’t been turned into a feature film that deserves it?”
