When he was 16, Martin Wallace worked at a gas station with a man named Greg. Wallace says Greg showed no outward signs of being a serial killer, but he turned out to be one.
From Wallace's essay in The Walrus:
And then, of course, there’s Greg. For whatever reason, we almost always end up working together, which is a relief to me. Greg is focussed, unflappable, with an easy sense of humour. We fall into a natural rhythm, never stepping on each other’s toes, always there for the other guy. When I start my shift and see Greg, I’m relieved—I know things will be all right.
But there’s one thing I don’t know about Greg, one thing that I only find out years later. Greg, you see, Greg is a killer.
