Spymaster's Prism is a prescient study of our unending struggle with Russia and its intelligence agencies' relentless effort to undermine our national security. Replete with the most salient spy stories, covert actions, and counterintelligence investigations from the beginning of the Cold War up until the eve of Putin's misguided march on Kiev, legendary spymaster Jack Devine builds a vivid and complex mosaic that illustrates how Russia has employed intelligence activities to undermine our democracy throughout modern history and lay the groundwork for this invasion. Devine tells this story through the gimlet-eyed perspective of a seasoned CIA professional who served his country for more than three decades, sometimes at the highest levels of the agency, offering objective and candid analysis that will bring new insight into Russia's invasion. Devine offers key lessons from our intelligence successes and failures over the past seventy-five years that illuminate how best to address our current strategic shortfalls, emerge ahead in the war, and be prepared for what's to come from any adversary. This cogent study illuminates why intelligence has been such a key driver in the war and how it will be a critical lever in order to prevail.
