Summary

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.
