The old lighthouse keeper found the body at dawn's first light. Inspector Mara Voss arrived quickly, her boots crunching on wet gravel. She noticed immediately that the victim's watch had stopped at midnight. Three guests claimed they heard nothing during the stormy night before. The lighthouse keeper insisted he had locked every single door himself. A torn photograph lay near the body, showing two smiling strangers together. Mara photographed everything carefully before the tide could wash evidence away. The victim was a reclusive historian researching local shipwreck legends for years. His notebook contained cryptic notes about treasure hidden somewhere on this island. Mara wondered which guest would crack first under her sharp questioning. The storm had passed, but danger still lingered in the salty air.
