Rain hammered the old lighthouse windows late that stormy night. Detective Mara Hale found the keeper lying near stone stairs. Blood pooled beneath his head like spilled dark red wine. She knelt slowly, noting the broken brass pocket watch nearby. Thunder cracked outside as the heavy door slammed suddenly shut. Someone else still remained inside this lonely tower with her.
