All the Devils are Here – Louise Penny

Description

There is more to solving a crime than following the clues.
Welcome to Chief Inspector Gamache’s world of facts and feelings.

On their first night in Paris, the Gamaches gather for a family dinner with Armand’s godfather, the billionaire Stephen Horowitz. But the evening ends in horror when Stephen is knocked down and critically injured in what Armand is convinced is no accident, but a deliberate attempt on an elderly man’s life.
When a strange key is found in Stephen’s possession it sends Armand onto the trail of secrets his godfather has kept hidden for decades. In a quest for truth that takes him from the top of the Tour Eiffel, to the bowels of the Paris Archives, Gamache finds himself ensnared in a web of lies and deceit that threatens to destroy everything – and everyone – he holds dear.
