The cold rain poured down upon the silent, empty street. A single lantern flickered above the dark and heavy door. Detective Miller stepped inside to find a very still scene. The body lay sprawled across the thick and velvet rug. Blood stained the ornate pattern of the expensive white floor. No weapon was found near his pale and frozen hands. Only the ticking clock broke the weight of the night.
