When three teens track down a missing chihuahua to an abandoned theme park, they stumble upon a chilling discovery: a corpse, strangled by his own camera strap. The victim was meant to be 400 miles away in London, where he’d promised a lot of people a lot of money. But every one of them has a solid alibi. As Haigh, Cherry, and Sunrise get pulled into the murder investigation, they uncover mafia connections, a still-operating ghost train, and gossiping grannies, revealing their quiet village is far more dangerous than they ever imagined.
