At the clapboard cottage on the edge of town, a pool of dark congealed blood glistened beneath the lone streetlamp. A scuffed leather notebook dangled from the left wrist of Constable Hale, who knelt slowly to peer at the corpse. A crumpled silk scarf lay tucked beneath the victim’s stiff right boot, its faded crimson threads soaking in old stains. Suddenly, a sharp tap echoed across the quiet street as a stranger’s shoes scuffed against the wet wooden porch step.
