Poirot faces his biggest challenge yet. He will have to call upon every one of his grey cells to defeat the enemy, and time, effort, and mustaches must all be sacrificed to the cause.

This is definitely a different style of Poirot. Usually he is involved in more of a mental game...this book has both mental and physical action. It has so many twists, turns, and double-backs, that sometimes it was hard to keep track.

An interesting departure from Christie's norm, and I enjoyed it this once, but I wouldn't have wanted her to write every Poirot book like this.
