Plot is strong up until the last third of the book, where my two complaints pop up:
1. a twist near the end that feels like Barclay pulled it out of his rear.
2. After the chaos throughout the story, which results in numerous deaths and property destruction, the book just...ends, with no real sense of closure.
I am a huge fan of Linwood Barclay, but this is the weakest of his thrillers.
