Review

⭐ Rating: 3.5/5 stars

I love a good locked-room mystery, and 6:40 to Montreal delivered exactly that atmosphere. The setup was clever a train car becomes both sanctuary and trap, with every stop of the journey ratcheting up tension. The first half was fast-paced, filled with quirky side characters, tense exchanges between passengers and crew, and small details that made you question who could be trusted!

The Canadian winter setting was vivid, you could practically feel the chill coming through the pages. The mix of suspense and atmosphere kept me hooked! Trying to pick up on clues about who (or what) was behind the unfolding danger.

That said, while the beginning had me absolutely hooked, the pacing faltered toward the 80% mark. The ending came a little abruptly, and felt slightly rushed compared to the careful buildup earlier on. I wanted more payoff from the tension that had been building throughout.

Still, the concept of a “closed train car” mystery is one I adore, and this book delivered that. If you love mysteries set in confined, isolated spaces where the atmosphere is as much a character as the people then you’ll probably enjoy 6:40 to Montreal!

Final Thoughts

6:40 to Montreal is a quick, engaging thriller with an excellent setup and an atmospheric winter setting that mystery fans will appreciate. While the ending may feel a bit abrupt, the journey itself is suspenseful and entertaining enough to make this worth the read.
