This book investigates the validity of the historical consensus that a unified group of Conservative Members of Parliament maintained a consistent, principled opposition to the policy of appeasement during the 1930s. Dr. Neville Thompson, a historian formerly of the University of Western Ontario, challenges the traditional narrative by examining the parliamentary records and political maneuvers of the era. He argues that Conservative dissent was largely sporadic and discontinuous rather than a cohesive ideological movement, suggesting that even prominent figures often associated with resistance were more ambivalent than retrospective accounts imply.

Historians and political scholars frequently cite this work for its rigorous challenge to established myths surrounding the anti-appeasement movement. The text is recognized for providing a nuanced, evidence-based corrective to the simplified narratives often found in popular political history.
