Model response

The grandfather clock struck midnight. Detective Sarah Mills received the call. "Another body has been found." She grabbed her coat quickly. Rain pounded the empty city streets.

The mansion loomed before her. Police cars lined the driveway. Officer Jackson met her halfway. "Victim is Margaret Whitmore, aged sixty." Sarah nodded and entered inside.

The library smelled like death. Margaret lay beside her desk. A letter opener protruded outward. Blood stained the Persian rug. Three suspects waited in parlor.

Sarah examined the crime scene. No signs of forced entry. The safe stood wide open. Valuable jewelry remained completely untouched. This was personal, she realized.
