Rain stitched the town's lamps with a dull metallic light. Detective Marlowe arrived, coat collar up against biting wind's teeth. A yellow tape hummed like nervous string across the lane. Body lay under the sycamore, face hidden by crimson scarf. Gloves placed neatly, hands folded as if offering apology tonight. Neighbors leaned from windows, eyes bright with fearful curiosity today. Footprints in mud stopped abruptly, leaving a single shoe behind. A neighbor's dog howled, then fell silent like confession itself. Marlowe's notebook held yesterday's weather and today's uneasy signatures neatly. He tasted ash on his tongue as memory stirred again. Streetlamp buzzed, casting everyone's faces into small accusatory moons now.
