Rain tapped windows while Detective Mara Vale studied the corpse. The victim wore a black coat and one missing shoe. A single red thread clung to the dead man's lapel. Mara lifted the red thread with tweezers and frowned slowly. Her partner Elias Reed entered carrying two steaming coffee cups. He said, "The mayor wants this solved before midnight tonight." Mara answered, "Then we should ask why the mayor cares." Elias set the cups down and stared at the thread. Outside, thunder rolled as a black car stopped nearby slowly. Mara looked up and knew the mayor had sent someone.
