This is a review of the free Kindle version.
The name didn't impress me too much, but to give you an idea of how good this story was, I read it in one sitting and ignore Poirot on the television for it.
The police detective is, for lack of a better phrase, the Black Ops member of Scotland Yard. If you need a place burgled, he's the one to talk to.
The villain is interesting and unusual. When he explains his motivation, it seems quite appropriate for the character.
The story takes place over years, very unusual for this type of story. Also, the trial isn't covered at all.
Easy to recommend for any mystery fan.
