The Last Murder at the End of the World

Turton (The Devil and the Dark Water) continues playing fast and loose with genre boundaries in this dazzling postapocalyptic thriller that blossoms into a race against time whodunit. A small island in the middle of the ocean has become the last refuge against the deadly, insect-filled fog that’s been covering the globe for the past 90 years. The 122 villagers who live and work on the island rarely question their regulated way of life, the elder scientists who keep them safe, or the disembodied voice named Abi beamed into their heads to coax them to sleep each night when the curfew bell rings. When the violent death of a teacher named Niema triggers a 12-hour memory wipe on all of the island’s residents, plus a fail-safe that will shut down the island’s defenses in 38 hours unless her killer is identified, villager Emory, armed with a curiosity nearly all of her peers lack, sets out to investigate. In the process, she unravels distressing secrets about the origins and operations of her supposed paradise. Turton smartly fortifies his themes of freedom and control by utilizing Abi, a manipulative HAL 9000 figure, as a semi-omniscient narrator, and he drops in enough clues for mystery fans to stay half a step ahead of Emory’s sleuthing without undercutting the impact of each reveal. This dystopian detective story fires on all cylinders. Agent: Harry Illingworth, DHH Literary. (May)
