At seven PM on a crisp autumn night, a small woman walked up her old stone steps to her door. Inside, the cool air smelled of jasmine and cinnamon, with a half-eaten cake still on the kitchen table. A few blocks away, the town’s seasoned detective sat at his wooden kitchen table, sipping strong black coffee slowly now. On the old table, a crumpled letter lay, its ink smudged, with a single red rose pressed inside it gently.
