Detective Marlowe arrived at the mansion just as the storm unleashed torrents against the ancient, creaking front doors ominously. Inside, the grand chandelier flickered erratically, casting long, jittery shadows over the marble floor where a body lay cold. The victim, a wealthy entrepreneur known for ruthless deals, was sprawled near the fireplace, a single knife wound evident in his chest. Guests gathered nervously in the drawing room, whispering rumors and exchanging suspicious glances, while the detective systematically examined the grisly crime scene. Outside, thunder rumbled deeply, masking the subtle but distinct sound of footsteps retreating into the darkness beyond the garden hedges quickly.
