The heavy rain fell hard against the cracked old window pane while the tired detective stared at the dead body. He knew that this case would be the one to finally break him if he did not stay careful today. The victim lay still on the cold marble floor, her pale eyes staring up at the dusty white ceiling fan. A small red stain spread slowly across the white rug, marking the spot where her life had left her body. He lit a cigarette to calm his nerves as the thunder rolled loudly outside the large open bay window frame. There was no sign of forced entry, which meant that the killer was likely someone she knew quite well indeed.
