The old lighthouse keeper found the body at dawn, waves crashing against the jagged black rocks below with cold fury. She had been beautiful once, the dead woman, her elegant silk dress now torn and soaked with cold, salty seawater. Inspector Marlowe arrived by noon, stepping carefully over the slippery tide pools while gulls screamed warnings from above the cliffs. He knelt down beside her pale form, carefully noting the strange bruises circling her slender throat like a dark necklace. No wedding ring graced her slender fingers, yet a faint pale tan line betrayed one that had been removed recently. The keeper mentioned a terrible storm last night, but Marlowe knew that storms never leave marks shaped like human fingers. Someone had surely murdered this poor woman elsewhere, then carefully carried her cold body down to the jagged rocks below. Marlowe slowly lit a cigarette and watched the gray horizon, already certain this strange case would change his life forever.
