Set in rural England in 1911, Tim Pears’s latest novel tells of a friendship between 12-year-old Leo, a precocious carter, and Lottie, the daughter of the master of the farm on which he and his father work. The Horseman is the first instalment of what will be a trilogy, and it is perhaps for this reason that the pacing of its plot feels somewhat preambular: Leo and Lottie bond sporadically over a shared love of animals, but little else of note happens until the very end.
