The novel "Glass Houses" continues the series of investigations by Chief Inspector Armand Gamache. This charming character was created by the pen of Louise Penny, the only person in the world who has won Agatha Christie’s prize five times.

Inspector of Police Gamache, trying to understand who the person is, attempts to talk to him and lead him away.

It turns out he is portraying a cobra-dora, a Spanish debt collector who, in the Middle Ages, pursued debtors silently, calling on their conscience. So why has the debt collector come to Three Pines?
