Welcome To The Enigma Series

Ian McKnight thought he had left the horrors of war behind after surviving the trenches of World War I. But when Madeline Shaw, a brilliant young cryptologist from Bletchley Park, arrives at his doorstep clutching a set of encrypted medieval parchments, his quiet existence is shattered. The 700-year-old texts hold a secret powerful enough to change the course of the war against Hitler—and McKnight is the only one who can unlock it.
What begins as an academic puzzle soon becomes a deadly race against time, plunging McKnight and Shaw into the unseen battlefield of Britain’s intelligence war—where nothing is as it seems, and no one can be trusted. With enemies closing in, they must rely on their wits—and each other—if they hope to survive.
But solving The Loch Ness Enigma may come at a terrible cost. Amid the ruins of a forgotten past, they uncover a deadly truth—some mysteries should never be unearthed… but some pasts refuse to stay buried.
