All the Devils Are HereAll the Devils Are Here

On their first night in Paris, the Gamaches gather as a family for a bistro dinner with Armand's godfather, the billionaire Stephen Horowitz. Walking home together after the meal, they watch in horror as Stephen is knocked down and critically injured in what Gamache knows is no accident, but a deliberate attempt on the elderly man's life. When a strange key is found in Stephen's possession it sends Armand, his wife Reine-Marie, and his former second-in-command at the Surete, Jean-Guy Beauvoir, from the top of the Tour d'Eiffel, to the bowels of the Paris Archives, from luxury hotels to odd, coded, works of art. A gruesome discovery in Stephen's Paris apartment makes it clear the secrets are more rancid, the danger far greater and more imminent, than they realized.
