The Black Wolf (Chief Inspector Armand Gamache #20) by Louise Penny

Several weeks ago, Chief Inspector Armand Gamache of the Surete du Quebec and his team stopped a domestic terrorist attack in Montreal, arresting the person behind it.
A man they called the Black Wolf.

Still recovering from wounds received in stopping the first attack, Armand is confined to the village of Three Pines, leading a covert investigation from there. In a quiet church basement, he and his senior agents, Beauvoir and Lacoste, pore over what little evidence they have. Two notebooks. A few mysterious numbers on a tattered map of Quebec. And a phrase repeated by the person they had called the Grey Wolf: In a dry and parched land where there is no water.

Gamache and his small team of supporters realise that for the Black Wolf to have got this far, they must have powerful allies. And soon, Gamache finds himself playing a lethal game of cat and mouse with an invisible foe who is gathering forces and preparing to strike.
