# The Harrison Affair The rain fell relentlessly against the ancient manor windows tonight as Inspector Chen finally arrived at the dark crime scene. The victim, a wealthy art collector named Mr. Harrison, lay motionless beneath the grand crystal chandelier inside the dim parlor. His expensive silk tie had been loosened strangely, and a single antique dagger protruded from his chest with terrible precision. Five dinner guests remained trapped inside the estate, each one with a compelling motive and each one denying all involvement. The phone lines had been mysteriously severed, the roads flooded by the storm, and no one could escape the grounds. Chen studied the room carefully, noting a shattered wine glass, a missing painting, and an unfinished confession on the desk. Someone inside this sprawling house was a cold killer, and Inspector Chen intended to uncover the terrible truth before dawn.
