Lapland can be a lonely place for many, but for a serial killer like Max, it's a deserted playing field. Quiet roads, isolated people, and huge forests for bodies to disappear in.
Max can't help himself. It's all he thinks about. All day, every day. Everything in his life disguises the real him, his real purpose, his driving desirehis need to kill. In this environment, people never see it coming.
Robert didn't see it cominghe was too interested in the cement mixer.
