The November fog clung thick to Blackrock Point’s rotting clapboard cottage, swallowing every pale star that tried to pierce it. Mia Carter, the remote peninsula’s only part-time ranger, lifted her dented brass flashlight and crunched over frost-crusted scattered oak leaves. She’d driven forty icy miles after the recluse lighthouse keeper failed to make his mandatory 10PM coast guard security call. The cottage’s splintered front door hung ajar, spilling warm golden lamplight out into the cold thick swirling gray coastal fog. She called out the old man’s full name, Elias Voss, but only dead heavy silence drifted back to meet her. She stepped across the threshold, her boot landing in a sticky pool of warm blood before her flashlight found him. Elias slumped over his scratched oak desk, a rusted brass letter opener protruding from the base of his bloodied skull. His welded wall safe gaped wide open, every tumbler picked, and only one small framed photograph had been taken away. Mia’s own blood ran cold when she spotted the only leftover photo, which bore her young teenage smiling familiar face.
