This one felt more like a creepy Stephen King novel rather than a detective mystery/thriller. Oh well who am I to judge when this one's my first Agatha Christie?
Would have given rated it 3 stars but damn that ending! It made
me give it one more star.
Also this book takes a bold plunge into the contentious debate over what should be considered crime and what should be labelled mere immorality. 4 stars it is.
