Rain hammered the old window. Detective Mara Cole lit up. The body lay face down. Blood pooled beneath the desk. A silver letter opener glinted. Her partner arrived five minutes later. Wait, let me try again. Rain hammered the old window. Detective Mara Cole arrived. The body lay face down. Blood pooled beneath the desk. A silver letter opener glinted. Shadows danced across pale walls. Someone had been here recently. The victim wore expensive clothes. His wedding ring was missing. A single footprint marked carpet. Mara knelt beside the corpse. She noticed something quite strange. The clock had stopped ticking. Its hands pointed at midnight. Yet dawn was breaking outside. Time itself seemed to lie. This case would prove difficult. Mara pulled out her notebook. The killer left no prints. But everyone leaves some trace. She would find the truth.
