Today I found a bright red stain on the door lock… I almost called the police

That evening, like many of us after a long day, I dreamed of only one thing: slipping into a blanket with a cup of tea. But one detail changed everything. As I approached the front door, my eyes caught sight of a strangely shiny red stain, right next to the lock.

My heart raced. I scanned the area; the hallway was empty… but this trace didn’t reassure me. “Is it a thief? A mark to come back later?”—the scenarios played out in my head like a detective series. Instinctively, my hand slid to my phone to call the police.

A simple trace… or a hidden message?
