Another amazing book! Seriously this author does not miss. I personally LOVE when the narrator speaks to the reader/audience, so make sure you also enjoy that before diving in because it's part of what makes this book/series so much extra fun. I love a train-themed locked room mystery and this one was absolutely addicting and perplexing. I never knew what was going on and I loved being along for the ride. The reveals, twists, and interesting tidbits were given at the exact right timing for dramatic effect and I loved how Ernest kept us updated on little foreshadowing clues without giving anything away. The golden age dramatic killer reveal at the end was amazing and I just had so much fun reading this book!

Note: I listened to the audiobook and really loved it!
