Detective Harris stared at the bloodstained carpet with cold silence. The victim's lifeless eyes gazed upward toward the ceiling forever. A shattered whiskey glass lay near the cold outstretched hand. Nobody had heard a single gunshot echo through the night. The locked door puzzled him more than the murder weapon. He noticed a faint smudge of lipstick upon the windowsill. This was no ordinary burglary gone wrong in the dark.
