The lighthouse keeper discovered the body at dawn, sprawled across the rocky shore beneath the towering white striped structure. Inspector Margaret Chen arrived within the hour, her notepad already filled with observations about the isolated clifftop crime scene. The victim wore an expensive tailored suit, now ruined by seawater and blood from the wound behind his left ear. No identification remained in his pockets, only a waterlogged matchbook from the Harbor Moon Hotel twenty miles down the coast. The lighthouse keeper insisted he'd heard nothing unusual during the storm, though his nervous fidgeting suggested he was lying. Chen noticed fresh tire tracks leading away from the lighthouse, disappearing where the gravel road met the paved highway. The waves had washed away most evidence, but a gold cufflink gleamed between two rocks near the body's position. As morning fog rolled in from the sea, Chen realized this murder was connected to something much larger than expected.
