Set against the backdrop of the diamond mining boom in Canada's far north, this is a story of money laundering, a Russian criminal gang, and bank accounts in tax havens. Mining engineer William Thompson is leading a double life at a remote diamond mine where he works in the Northwest Territories. He's made a bargain with the devil, and it’s drawing him ever deeper into an abyss from which he’s desperate to escape. But his carefully laid plans to leave it all behind and regain his freedom spawn consequences he could never have imagined. In the swirl of international intrigue that follows, Ed Zelensky, a maverick officer with the Royal Canadian Mounted Police, finds himself immersed in one of the biggest cases of his career, with Thompson at its center. What links Thompson and his activities at the diamond mine to a brutal assault in Mexico, a Russian criminal gang, and large-scale money transfers to banks in the Cayman Islands and Switzerland? Zelensky has to use every trick he knows to get to the truth.
