After Soviet cipher clerk Igor Gouzenko defected in 1945, Canada was shocked by the revelation that its own citizens were engaged in espionage for the Soviet Union. "P.S. Burn after Reading": The Kellock-Taschereau Commission and Soviet Espionage in Canada (University of Toronto Press, 2026) explores how the Canadian government used the controversial Kellock-Taschereau Commission—sometimes judiciously, sometimes not—to uncover and thwart domestic spies during the early days of the Cold War.

Drawing on a wealth of sources, including the Commission’s extensive records, GRU documents turned over by Gouzenko, American Venona decrypts, Soviet KGB archives, and newly released British MI5 and MI6 files, authors Dr. Reinhold Kramer and Dr. Tom Mitchell provide a comprehensive account of the crisis. They reveal that, despite some civil liberties missteps, the government’s suspicions were largely justified.

The book weaves together the evidence against the spies, the tradecraft of Soviet espionage, complex legal challenges faced by the state, and the political fallout. With access to hundreds of newly released British intelligence files, P.S. Burn After Reading offers both specialists and general readers fresh insights into the espionage crisis of 1945–46 and the pivotal role it played in exposing Canada’s postwar security and intelligence vulnerabilities.

This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

In Contested Continent: The Struggle for America, c.1000-1680 (Oxford University Press, 2026), the newest installment of the acclaimed Oxford History of the United States series, Peter C. Mancall recounts how North America was forged from the experiences of millions of Indigenous women and men as well as Europeans and Africans. This history spans the continent from the North Atlantic to the West Indies and includes the entire Atlantic basin, telling a new story about the origins of major aspects of American culture. He illuminates the rise of a booming trans-Atlantic economy based on the extraction of abundant American natural resources; the central role that European migrants and their descendants played in the enslavement of Africans and the displacement of Indigenous peoples; and the spread of self-governing polities where many enjoyed religious freedom. None of these developments was inevitable. Conflicts broke out frequently as different peoples battled over precious resources. Europeans' appetites for material gain and expanding Christendom brought horrific consequences for those brutalized, enslaved, and vulnerable to infectious diseases. This is a sweeping history of developments crucial to the eventual founding of the United States. Contested Continent underscores the titanic struggles between the peoples who had populated the Americas for centuries and the migrants from the Old World who initiated changes that created a New World that offered boundless opportunities for some and crushed the aspirations of others.

In the early twentieth century, as variety shows flooded Canadian stages, new forms of blackface, inspired by modern forms of amusements, changed the theatre. In this era marked by progressive social reforms, the stage embodied the modern ethos of imitation, mimicry, and change.

Staging Blackface in Canada: Public Amusements, Variety Shows, and Racial Acts in an Age of Imitation, 1898-1919 (Wilfrid Laurier Press, 2026) covers a moment when Canadians did not produce professional theatre, but they built amusement parks, wrote songs, and produced records. As the stage (drama), and its variants (burlesque, light opera) adapted elements from the new stages (amusement parks, social dance, and film), the modern culture popularized forms of blackface that impacted white, Anglo-Protestant, and English-speaking audiences, and drew theatrical criticism.

This book explores a twenty-year period in Canada’s history when there was no media regulation, and no mandate to promote Canadian culture. Through an examination of theatrical reviews, images, and textual records, Staging Blackface in Canada locates how the Canadian stage became a playground for ethnic jokes, racial caricature, and women’s emancipation. It also locates some of the first Black musicals and operas to appear on Canadian stages.
