Most of the reviews and recommendations focus on 'The Woman in Cabin 10' and 'The Turn of the Key' for that locked-room, claustrophobic suspense vibe, which are solid, but I feel like they're almost too polished? Her earlier one, 'In a Dark, Dark Wood,' has this raw, anxious energy that I keep coming back to. It’s a reunion-party-gone-wrong setup, which sounds familiar, but the first-person narration from the socially anxious writer just nails that feeling of being trapped in a social situation that’s spiraling. The tension feels less about a grand, external conspiracy and more about the dread of a friendship group unraveling, which to me is more psychologically unsettling.
Her later novels get more intricate, sure, and 'The Death of Mrs. Westaway' is a fantastic homage to Gothic tropes, but for pure psychological unease rooted in believable character dynamics, I’d rank 'In a Dark, Dark Wood' higher than its overall rating might suggest. Sometimes the debut, with its slightly less slick plotting, captures a specific panic more authentically. The ending might not be her most twisty, but the journey there is a masterclass in sustained, low-grade terror fueled by guilt and memory.
It also seems to split readers more—some find the protagonist frustrating, which I think actually adds to the book's success. You’re not just observing suspense; you’re lodged in the head of someone making increasingly questionable choices out of sheer anxiety. That’s the psychological hook for me, more than the technically perfect mysteries she wrote later.
