I love books that promise "untold stories". This one does and it delivers. Who knew that a Canadian was the first to warn the world what the Nazis were up to, and to do it years before anyone else was even talking about Nazis? Winthrop Bell is a name you should know, and thanks to Jason Bell and his deep dive research you now will. — Peter Mansbridge

Brilliantly researched, Cracking the Nazi Code upends our conventional, often inaccurate, understanding of the Nazis’ rise to power after WWI. It took the stunning intelligence work of Winthrop Bell, a Canadian spy working for MI6 in Germany, to decipher what was really going on. How did Hitler, an insignificant minion, manage to climb the ladder of power? How wide-ranging was his genocidal intent? As Bell pursues the truth, the twists and turns of his life are fascinating. We come away with a deep respect for intelligence work at its finest. A page-turner, one of those books not to be missed. — Rosemary Sullivan, Stalin’s Daughter

Written with uncommon verve, wonderful detail, and deep insight gained from previously inaccessible archival records, Cracking the Nazi Code reveals the key spy work of Winthrop Bell. His secret fieldwork revealed insurrection, revolution, and the rise of the vile ideology that would underpin the Nazi party. Bell’s dangerous missions saved countless lives, supported battered democratic regimes, and provided British spymasters and Canadian political leaders with crucial information to avert disaster. Cracking the Nazi Code reminds us of the fragility of nations after war and how easily they can slide into chaos as demagogues prey upon the vulnerable, helpless, and hopeless. — Tim Cook, Vimy: The Battle and the Legend

If you think you know everything about World War II, you need this book.

Cracking the Nazi Code takes you along on one man’s dangerous quest to discover the truth and convince world leaders of perils to come. — Gregory A. Freeman, The Forgotten 500

Move over William Stephenson. It turns out "the Man Called Intrepid” wasn't Canada's only WWII master spy.

“A deeply researched, intriguing portrait of Winthrop [Bell]…The British agent was not the only person who got Hitler mostly right, but he was one of the earliest to do so.” — Wall Street Journal
