And just like that, I already have my first contender for best read of 2026 and it’s a straight-up old-fashioned whodunit. There’s just something deeply satisfying about a mystery that knows exactly what it wants to do, and Murder at World’s End absolutely nails it, delivering a treasure that feels like a love letter to the Golden Age of detective fiction.

The novel is set in Cornwall in 1910, the same year Halley’s Comet sparked widespread panic as a sensationalist media warned that all life would perish as Earth passed through the comet’s poisonous tail. Ensconced in his remote island estate ominously named World’s End, the Viscount of Tithe Hall has a plan for himself and his family to survive the apocalypse. Every window, door, and chimney will be sealed down to the tiniest keyhole, supposedly to protect the manor’s guests and servants from all kinds of dangerous gases or noxious space dust falling from the heavens.

On the eve of Halley’s expected appearance, an earnest young man named Steven Pike arrives at Tithe Hall and steps into a world of utter chaos. Recently released from prison for a crime he didn’t commit, he has come desperately in search of work, knowing how slim his chances are due to his questionable past. With the pre-comet preparations in full swing, however, the place is short-staffed and Steven is hired on the spot. He is then given the curious task of chaperoning Miss Decima Stockingham, the Viscount’s curmudgeonly and foul-mouthed octogenarian aunt who has already driven away all her lady’s maids. Warned that the old lady might not be entirely in possession of her marbles, Steven is surprised to find Miss Decima is in fact far less unhinged than her reputation suggests, with a mind as sharp as her interest in science, though her spectacular temper and lack of tact are unfortunately very real.

Obviously, the world has not ended by the time morning arrives, and the houseguests all emerge from their sealed rooms in a state of collective bemusement and relief—all except one. Sometime in the night, the Viscount was murdered, and his body is discovered alone in a room that had been sealed from the inside. On the surface, the crime appears impossible, though with the island cut off by the high tide, the only certainty is that the killer is someone already at World’s End. As the newest arrival and a former convict, suspicion immediately lands on Steven, but with the help of Miss Decima, the two set out to clear his name by solving the case.

Eccentric suspects, multiple nefarious motives, a literal locked room—The Murder at World’s End has it all. From the very first page, it had me completely hooked, and by its end, I was already giddy with excitement to find this is only the first of hopefully many more Stockingham & Pike books to come. What I loved about the story is how unapologetically classic it feels. This is a proper mystery where the clues matter, the motivations make sense, and the reader is invited to play along rather than be distracted by spectacle. Of course, there are red herrings aplenty, but in my opinion, they are fair ones where the plot never resorts to outrageous twists or last-minute revelations to force a surprise. Instead, the novel features sensible detective work that unfolds with patience and care, rewarding close attention and logical thinking, which made the ending all the more satisfying.

Also, I truly enjoyed the unlikely detective duo of Miss Decima and Steven. The latter’s gradual development is wonderfully handled, portraying his transformation from a skittish young man into a confident go-getter who learns to trust his instincts. And how I loved Miss Decima! Witty, brilliant, and having absolutely no patience for bullshit, she steals every scene she’s in and completely owns it, and yet, while she can certainly be a lot, it never feels too forced or over-the-top like it’s tipping into caricature. What really makes it work, though, is the dynamic between the two characters. Their partnership forms naturally, initially built on shared curiosity and then later mutual respect, eventually evolving into a friendship that was easily the highlight of the entire book.

Historical fiction fans will further appreciate the setting. The looming presence of Halley’s Comet and the hysteria surrounding it serve as such a cool backdrop for the story, giving it an eerie and almost mystical atmosphere. Tithe Hall itself stands as an intimidating presence, and the author uses the environment—the surrounding sea, the dark woods nearby, and even an honest-to-goodness hedge maze—to incredible effect.

In the end, The Murder at World’s End is exactly the kind of mystery I’ve been craving. I could hardly put it down, and every time I was forced to, I found myself jonesing for the next time I could pick it up again. Clever without being convoluted, charming without being pretentious, and most importantly rooted firmly in the traditions of classic detective fiction, this novel is a perfect reminder of why the genre is so beloved and enduring. I would happily follow Steven Pike and Miss Decima Stockingham into as many investigations as Ross Montgomery is willing to write.
