The old lighthouse keeper found the body at dawn today. Inspector Mara Voss arrived quickly and secured the entire crime scene. Blood pooled strangely on the spiral staircase's worn wooden steps. Three guests remained inside the tower, all claiming complete innocence. The victim was a reclusive historian studying local maritime disasters. Rain lashed against the windows as thunder shook the ancient structure. Mara noticed muddy footprints leading toward the keeper's quarters. Someone had clearly tried to destroy evidence before her arrival. The lighthouse beam had failed mysteriously during the previous night. Each suspect possessed secrets that could explain this brutal murder.
