Parting shot / Linwood Barclay.

When a young girl from Promise Falls is killed by a drunk driver, the community wants answers. It doesn't matter that the accused is a kid himself: all they see is that he took a life and got an easy sentence. As pack mentality kicks in and social media outrage builds, vicious threats are made against the boy and his family. When Cal Weaver is called in to investigate, he finds himself caught up in a cold-blooded revenge plot. Someone in the town is threatening to put right some wrongs...And in Cal's experience, it's only ever a matter of time before threats turn into action.
