Model response

The lighthouse keeper lay dead. Blood pooled beneath his head. Detective Sarah Mills arrived early. Waves crashed against jagged rocks. She climbed the spiral stairs. His body blocked the entrance. A lantern flickered in darkness. The victim clutched mysterious papers. Wind howled through broken windows. Someone had been here recently. Muddy footprints led toward cliffs. The killer had escaped quickly. Sarah examined the cold corpse. Strange symbols covered the papers. This murder seemed quite personal. The lighthouse held many secrets. Dawn broke over the scene.
