Toronto in winter: a city of silence, glass, and reflection.When Detective Evelyn March investigates a series of impossible recordings-voices speaking from beneath the frozen lake-she uncovers a pattern of sound that defies reason. Each clue leads her closer to a system known only as the Underlight, an experimental network buried beneath the city, designed to record and preserve sound.As the investigation deepens, March and her team discover a disturbing truth: the water itself is an archive. A living memory that repeats what people try to forget. The more she listens, the more the city begins to speak back-using her own voice.From the abandoned ferry slips of Lake Ontario to the steel corridors of the Harbourlight complex, Lake Effect builds a world where science and superstition blur, and memory becomes the most dangerous form of evidence.Haunting, atmospheric, and deeply human, Arthur Blackwood's Lake Effect explores the fragile boundary between technology and faith, guilt and reflection. A psychological thriller that combines procedural realism with metaphysical tension-a slow, relentless descent beneath the frozen surface of memory.If the city remembers everything, who decides what it forgets?
