Rain stitched the town awake. Streetlights bled into puddled reflections. Margot found him on stairs. His coat smelled of tobacco. One shoe lay oddly askew. Blood darkened the cobblestones underfoot. A shard glinted near hand. He clutched a damp letter. Margot's breath hitched; police whispered. The sergeant wiped his brow. Lantern light revealed a footprint. Footprints ended where alley narrowed. Someone hummed an old lullaby. Silence answered with a siren. Margot touched the damp envelope. Name on it was familiar. He had enemies, everyone knew. Night swallowed another small secret. Investigation would unravel many lies. Dawn hesitated over the rooftops.
