Still Life

Still Life (Chief Inspector Armand Gamache #1) - Louise Penny

 

A cozy, traditional detective mystery. I didn’t like all the characters, but I found them all intriguing. The most interesting ones were probably the least pleasant or admirable. And that's significant, because in this story it is the personalities of the characters (including the victim’s) that define the crime and dictate the solution.
