The lighthouse beacon sputtered, casting frantic shadows across the storm-lashed cliffs where Eleanor's body lay cold, pale, and utterly still. Detective Miller had not expected another murder, especially not one involving his estranged childhood best friend on such lonely night. Her right hand clutched a sodden theatre ticket dated yesterday, yet the lighthouse closed years ago for mysterious bureaucratic reasons. The wind howled louder, extinguishing his lantern, leaving only the ticket's faint phosphorescent glow for illumination inside oppressive suffocating darkness. Someone had staged this scene meticulously, and Miller realized the killer was still watching nearby from shadows within listening silence.
