The old lighthouse keeper found the body at dawn's first light. Blood pooled dark and still on the ancient stone floor. No one else had been here for three full days. Sheriff Mara walked carefully, counting each step she took. The victim wore a coat from another decade entirely. A single white rose lay beside her cold hand. Rain lashed against the windows like angry ghost fists. Mara photographed everything before the wind could disturb evidence. The lighthouse beam swept across the room every twelve seconds. She wondered who would kill in such a place.
