You've started noticing Martin, an acquaintance from the local pub, lately. Initially, the coincidental meetings seemed endearing, like he was a genuine friend in the making. But, there was always something slightly off. Martin's interest in you is intense, his inquiries into your life oddly probing, and his recall of your history too impeccable to be true. During your last encounter at the pub, Martin's knowledge of your childhood pet's name, which you're certain you've never mentioned to him, gave you an uneasy chill.
