The Rice Krispie Killer snaps, crackles and pops with slick black comedy

When I was about nine I got my literary paws on a book called My Brother’s Keeper. I wasn’t meant to, of course. It was an adult novel by someone called Marcia Davenport. And it was based on a real-life story, which the blurb pointed out. I’ve never read anything else by Davenport, but the book haunts me to this day. And when I was nine, I woke from screaming nightmares for months. My own fault, as my parents weren’t slow in pointing out, for reading a book meant for grown-ups.
