The grandfather clock chimed midnight in the empty mansion hall. Detective Sarah Chen stepped carefully over the broken crystal wine glass. Lord Pemberton's lifeless body lay sprawled beneath the grand oak staircase. Blood pooled around his silver hair in a crimson dark circle. The butler stood trembling by the doorway, his face completely pale. "I found him like this just twenty minutes ago, Detective." Sarah noticed the study door was open, papers scattered everywhere inside. A half-finished letter lay on the mahogany desk, ink still wet. The fire crackled softly in the stone fireplace, casting eerie shadows. Something glinted near the victim's outstretched hand in the dim light.
