Finished reading The Last Policeman by Ben Winters.
This is the first book in a trilogy. It borders on sci-fi. It is told in the first person by Detective Hank Palace. The setting is Concord on the brink of an earth destroying asteroid. There has been another suicide, which is pretty common given the circumstances. But Hank believes there is more to it than a suicide. Despite the end of the earth coming, Hank is seeking the truth.
The story is a "murder mystery" but also explores what pre-apocalyptic earth may be like. People are "going bucket list"; quitting their jobs and going to do whatever they have always dreamed about. Some people have become so anxious and hopeless that they are taking their own lives. Groups are planning how to survive; building vessels to leave earth, hoarding food and weapons.
Others like Hank are trying to keep up normalcy and law and order.
You will want to read the next two in the trilogy since we haven't gotten to "the end", when this first book is finished.
Quick read, not a lot of superfluous description but full of surprises.
This book won Edgar Award from the Mystery Writers of America, and the Philip K. Dick Award for Distinguished Science Fiction for this trilogy.
