The House of a Hundred Whispers is set in Allhallows Hall, a rambling Tudor mansion on the edge of Dartmoor. After the death of its master, Dartmoor Prison’s former governor Herbert Russell, his estranged children gather to inherit the estate. But within hours of arriving in the spooky old house, five-year-old Timmy has vanished without a trace. A sumptuously designed hardcover with a picture of those desolate moors, anyone picking this book up would expect a haunted-house story in the classic mould, and that’s certainly where it starts. However, Masterton’s tale veers off in a series of smartly and sharply executed swerves, and ends up in a very different place – less The Haunting of Hill House, more The Exorcist or 2018’s Here Comes Hell.
