The rain fell without mercy. The street was completely empty. A single lamppost flickered weakly. Then a scream shattered silence. Detective Hayes arrived minutes later. The body lay near stairs. Blood pooled on wet cobblestones. A woman stood there trembling. Her eyes were wide open. She could not speak clearly. The detective knelt down slowly. He studied the pale face. A single gunshot wound gaped. No weapon was in sight. This was no random killing. The rain washed away evidence. Time was already running out.
