The Stonehill Detective Agency, renowned by many to house the best detectives in England, has solved cases left-and-right for years. But a series of murders and disappearances in a once-quiet city leaves even their best investigators stumped. Prodigy detective Arthur Callum was sent to the city of Duke's Lake to investigate the sudden vanishing of a teenage girl. But the evidence points to the girl's family as the culprits, which they adamantly deny. Everything just doesn't add up. Perhaps, death just reveals the monsters hidden behind the veils of morality—some are unaware, while others take it with open arms.
