Karen McManus leans hard into small-town secrets in Two Can Keep a Secret, and it works because she refuses to pretend anyone in Echo Ridge is innocent. The story follows twins Ellery and Ezra as they move in with their grandmother, landing in a town still haunted by two disappearances: their aunt years ago, and a homecoming queen more recently. McManus uses these old wounds as pressure points, and the town feels like it’s been holding its breath for decades.
The book is strongest when it focuses on Ellery’s obsession with true crime. Her suspicion of everyone around her isn’t just a personality quirk — it’s rooted in what she doesn’t know about her own family. Malcolm’s POV is weaker at times, but it pays off because he stands right in the blast radius of the town’s judgment. The dual perspectives give the mystery room to twist without feeling forced.
McManus keeps the pacing tight. The clues are seeded early, and even when the red herrings feel deliberate, they don’t stall the story. The atmosphere is the real hook: homecoming floats at night, creepy theme-park rides, a town determined to pretend things are “normal” when everyone knows they’re not.
The ending lands hard. It’s not neat, and it doesn’t try to be. The final reveal is the kind that forces you to re-evaluate everything you thought you understood about the family dynamics. It’s bleak in the right way — morally messy, emotionally sharp.
Overall, Two Can Keep a Secret is less flashy than One of Us Is Lying, but it’s colder, more controlled, and honestly the better book. It knows exactly what kind of story it wants to tell: a murder mystery where the truth hurts just as much as the lies.
