Heavy rain tapped violently against the shattered library window while Detective Miller carefully examined the lifeless body on the floor. Lord Blackwood lay sprawled across an expensive Persian rug, with an antique silver letter opener buried deep inside his chest. A gold pocket watch had stopped at midnight, shattered by the violent impact of the old man hitting the ground. The heavy oak doors were locked securely from the inside, leaving no obvious escape route for the clever midnight assassin. Beside his cold left hand rested a crimson envelope containing a single cryptic message written in freshly spilled human blood. Miller sighed deeply and pulled out his leather notebook, realizing that everyone inside this isolated mansion was now a suspect.
