Rain fell softly on the old cobblestone street that night. A single lamp flickered weakly above the deserted town square. Detective Miller approached the grim scene with a heavy heart. The body lay still, a dark shape on the ground. A silver knife protruded from the victim's chest, gleaming dully. Blood pooled around the corpse, black in the dim light. Miller noted the missing wedding ring on the left hand. The shattered pocket watch had stopped at exactly midnight sharp. The victim's face was frozen in an expression of surprise. Who could have wanted this wealthy businessman dead, and why?
