Detective Sarah Chen stared at the body through the rain. Blood from the victim's chest wound spread across the pavement. The neon hotel sign flickered weakly against the night sky. Forensics carefully documented each detail of the gruesome crime scene. She noticed small scratches running down the dead man's arms. Thunder crackled overhead as her partner approached with new information. The victim's wallet lay empty just feet from his body. Hotel security cameras had mysteriously stopped working hours before death. A single gold cufflink glinted in the victim's clenched hand. Sarah knew this case would be anything but routine now.
