The lighthouse keeper found Eleanor dead beside the shattered lantern. Rain hammered the windows while thunder rolled across the bay. Detective Mara Quinn arrived before dawn with coffee and questions. Nobody admitted hearing screams above the storm's relentless howling wind. Her brother Thomas stood silently, clutching her bloodstained silver locket. A single muddy footprint led toward the locked cellar door. Mara noticed something glittering beneath the victim's pale lifeless hand. It was a brass key engraved with tiny mysterious initials. Outside, someone watched from shadows, waiting for their moment patiently. By morning, three suspects lied, and one killer smiled secretly.
