THE MURDER AT WORLD'S END

A vainglorious viscount is murdered in this 1910-set mystery—Montgomery’s first novel for adults and the launch of the Stockingham & Pike series.

As the novel opens, narrator Stephen Pike, not yet 20 years old and fresh from a two-year stint at a London prison, finds himself in Cornwall at World’s End, taking a job as a second footman at a remote manor house. (So far, so Downton Abbey.) He arrives at a time of high anxiety: Lord Stockingham-Welt has seen to it that the windows of Tithe Hall have been boarded up in anticipation of Comet Halley’s appearance—“This time, it will be the end of the world,” he insists. The comet spares the earth, but the night doesn’t spare the viscount: The next morning, he’s found dead in his study, which was locked from the inside, with an ancestral crossbow’s bolt in his eye. Who better than un-alibied recent inmate Stephen to take the blame for the murder? To Stephen’s aid comes Miss Decima Stockingham, the viscount’s elderly great-aunt, who makes Downton Abbey’s Violet Crawley seem like an earth mother. A frustrated scientist, Miss Decima hated her late nephew—“Conrad stole my inheritance, my sister, my career…everything”—but she hates Stephen’s victimization more. The book’s ingenious reveal, which hinges on a long-buried Stockingham family secret, is reached through a combination of Miss Decima’s scientific-inquiry-fueled deductions and Stephen’s precocious puzzling (the story features both a hedge maze and a spot-the-difference-style brainteaser). The odd-couple intergenerational sleuthing duo is a welcome new arrival on the historical-mystery scene, with Stephen’s squeamishness about Miss Decima’s filterless fuming a mainstay of the book’s unremitting humor (Stephen: “I’d never heard language like it…and I’d just spent the last month sharing a bunk with a man called Filthy Mick”).

A paragon of the locked-room historical mystery.
