The rain began at midnight. Fog crept across wet cobblestones. A single scream split silence. Detective Miles noted the time. The body lay perfectly still. Blood pooled beneath silk sheets. No sign of forced entry. A half-eaten meal sat nearby. Two glasses, but one lipstick. The window was locked tight. Miles picked up the phone.
