"For the past two months, someone has been leaving small anonymous gifts at my front door. Always left before dawn, always unsigned: an embossed leather journal, artisan pralines, a ceramic mug, fresh flowers. Every one is wrapped in plain brown paper and tied with the same burgundy ribbon. The journal had my initials on the cover, and the flowers were my favourites, something only someone close to me would know. It's making me terrified in my own home."

"I'm certain it's Marcus Vale. We worked together at Novus FinTech until I left in June. He ignored polite rejections, and when I told HR, he resigned the following week. The police say suspicion isn't proof, and my doorbell camera is a cheap one with a scratched lens that fogs up on cold mornings, so his face is just a blur every time. I can't pay you to sit outside every dawn, so I need you to work out which morning he'll come next. Marcus posts almost everything publicly on SnapTrail. If you study his habits, there has to be a pattern."
