The Nature Of The Beast by Louise Penny ****

Armand Gamache has retired to Tall Pines, but finds himself involved again in crime solving when a young boy, Laurent, is killed after telling everyone about a huge gun he had found in the woods. 

Gamache, his son-in-law Beauvoir, and Chief Inspector Isabel Lacoste are kept busy when the huge gun is actually found in the forest with a strange and evil etching on it. Several days later another person, Antoinette is killed, and Gamache discovers she was the niece of a man who assisted in its construction.

The plot becomes thicker, and the danger greater as more possible suspects seem to appear. In all of this, the cosy little town with its BandB and the bistro, the bookstore, the grocery store, offers a contrast to the evil gun resting in the forest.

Then ding has all the ends tied up nicely, then you read the afterword by the author and find that this story is based on facts!
