Caroline Grills was an Australian serial killer, who developed a great delight in poisoning her relatives when she became bored. In some of her murders she benefitted financially in others none what so ever. She appeared as a most unlikely serial murderer being a mother, grandmother and great-grandmother and generally liked and loved by all who knew her. At her trial the prosecutor said that she was "a killer who poisoned for sport, for fun, for the kicks she got out of it, for the hell of it, for the thrill that she and she alone in the world knew the cause of the victims' suffering".
I have read quite a few of the books in the bus stop guides and they do pretty much exactly what you expect - they are short but to the point, punchy and full of facts about the incidents and what happened. This one is ok - 3 stars from me
