Another installment in the excellent series of Chief Inspector Gamache books by Canadian author, Louise Penny. How the light gets in ties together many of the threads from the earlier novels in this series but as the story progresses, for those starting with this title, the author provides an outline of what has happened previously. However, to get the most from this series of books, they should be read in order.
When Armand Gamache is contacted by Myrna Landers about a friend who is missing, he goes to Three Pines to hear the full story. This leads to the discovery of a murder and a story that began in the 1930s. Solving this mystery is only one of the threads in this book as internal problems in the Surete de Quebec have intensified resulting in members of Armand Gamache's team being dispersed throughout other departments in the Surete. Chief Inspector Gamache is particularly concerned about the welfare of Jean-Guy Beauvoir whose health and mental state continues to decline. With his few remaining supporters, plus the assistance of his friends at Three Pines, Armand Gamanche is determined to find out what is going on at the Surete and who is trying to destroy him, even though it may mean him losing his job and possibly his life.
Louise Penny not only writes about crime, she writes about people and the reader becomes immersed both in the story plus the lives of the characters and the often difficult decisions they have to make. A range of emotions are encountered when reading these books as the characters encounter the good and evil that makes up life. It is extremely easy to become totally involved in this world created by Louise Penny and not want to do anything else until reaching the end of the novel.
