Le Vallon

Many reviewers praise the book for its compelling and twisty mystery, featuring a good number of red herrings that kept them guessing the culprit's identity. Readers found the character development to be a standout feature, noting that the author delves deeper into the psychological aspects and inter-relations of the cast, making them feel more real and complex than in some other works. The novel is described as an excellent, character-driven drama, offering a refreshing change of pace and a more mature, thoughtful tone. Specific appreciation is given to the vivid setting, the cleverness of the murder setup, and the astute understanding of human nature woven throughout the narrative. Some even consider it one of Christie's best works, highlighting its unique ambience and satisfying, albeit sometimes surprising, resolution.

Despite its strengths, the book receives criticism for several aspects. A recurring point is the diminished role of Hercule Poirot, who many feel takes a backseat, appearing almost decorative or having a late and lukewarm intervention, which disappointed fans expecting his usual dramatic deductions. The pacing is frequently mentioned as a drawback, with the murder occurring relatively late in the story - sometimes after a third of the book - and a perceived over-reliance on character exposition, reflections, and domestic tension that can slow the action and make it difficult to maintain interest. Some readers found the characters, particularly the victim, to be unlikable or irritating, and felt that the mystery itself was either too evident or that its resolution arrived too weakly, lacking the ingenious deception or brilliant lucidity characteristic of the author's other works. Additionally, some comments noted disjointed dialogue and an overall feeling that the book didn't quite succeed as a traditional Poirot mystery.

Overall, this book appears to be a divisive entry in the author's bibliography, often seen as an experimental or unusual work that deviates from her typical formula. While some fans were left disappointed by the shift in focus and pacing, others lauded it as a sophisticated and psychologically rich novel that showcases the author's versatility and depth in characterization. It is recommended for Agatha Christie completionists and those who appreciate character-driven dramas and psychological mysteries over fast-paced, plot-centric detective work. Readers who enjoy a slower burn, intricate character studies, and are open to a less traditional role for Hercule Poirot will likely find this book a rewarding and thought-provoking experience, even if it is tinged with sadness or a departure from the author's usual style.
