Executive summary

Ben Macintyre’s bestselling book The Spy and the Traitor recounts the career of Oleg Gordievsky, a KGB colonel who spied for MI6 and—according to Macintyre’s reporting and multiple reviews—provided “the single largest ‘operational download’ in MI6 history,” played a key role in damaging the KGB, and later escaped Moscow in 1985 after his exposure by CIA mole Aldrich Ames [1] [2] [3]. The book is widely praised as a gripping true-spy narrative and is in active circulation and adaptation talks for television [4] [5].

1. A classic Cold War double life: what the book claims

Macintyre’s narrative centers on Oleg Gordievsky, a senior KGB officer who became a British asset and supplied a continuous stream of sensitive intelligence that Macintyre and reviewers say materially damaged the KGB; reviewers describe the case as “the single largest ‘operational download’ in MI6 history” and credit Gordievsky’s secrets with significant Cold War impact [1] [2]. Macintyre frames Gordievsky’s work as a long-running, high-stakes human intelligence operation—complete with microfilm drops, a Safeway shopping-bag signal to trigger escape plans, and a dramatic 1985 exfiltration attempt [6] [1].

2. The traitor in story and title: Aldrich Ames’ role

Macintyre and critical coverage position Aldrich Ames—the disgraced CIA officer who sold secrets to the KGB—as the foil in the tale: Ames’ betrayals included revealing Gordievsky’s cover, which precipitated Gordievsky’s peril and need to escape [3] [1]. Reviewers use Ames as a moral counterpoint—Ames is portrayed as a “greedy bastard” in accounts quoted by critics, while Gordievsky is cast as ideological and courageous [3] [1].

3. How critics frame Macintyre’s method and access

Reviewers note Macintyre’s strengths as a storyteller and his access to principal participants: he interviewed the officers involved and Gordievsky himself [7] [1]. Critics applaud the book’s thriller-like pace and psychological depth, while also acknowledging that Macintyre, as an “intelligence outsider,” lacks access to some classified MI6 archives—yet he compensates through interviews and reconstruction [4] [7].

4. Reputation, sales and cultural reach

The Spy and the Traitor is a New York Times bestseller and has been widely reviewed and promoted across outlets, described repeatedly in marketing and reviews as perhaps the greatest Cold War espionage true story [2] [8]. Macintyre’s standing as a popular chronicler of intelligence history is repeatedly invoked in promotional material and reviews [4] [8].

5. Adaptation and the entertainment angle

The book has attracted screen interest: producers who adapted other Macintyre books are reported to be developing The Spy and the Traitor for television, with Deadline and industry coverage noting an adaptation as “first up” among projects [5] [9]. That commercial interest amplifies Macintyre’s narrative choices and may encourage dramatization even as it spreads the book’s central claims to wider audiences [5].

6. Praise, hyperbole and the risk of legend-building

Multiple sources and reviews embrace grand framing—phrases like “the greatest espionage story of the Cold War” recur in publisher copy and reviewer shorthand [2] [10]. Reviewers and sellers frequently echo superlatives, which can conflate rigorous history with thriller pacing; Kirkus and Publishers Weekly nonetheless treat the narrative as both well-sourced and compelling, while acknowledging literary flourish [3] [1].

7. What available sources do not mention

Available sources provided here do not mention any primary MI6 archival material released to Macintyre, nor do they supply raw documents in support of every operational detail; sources emphasize interviews and participant recollection rather than newly opened official files [7] [4]. Available sources do not mention independent archival confirmation beyond what reviewers and promotional copy report.

8. Reading advice and how to judge competing claims

Readers should treat Macintyre’s account as well-sourced narrative history built from interviews and participant testimony, corroborated in reviews as persuasive and dramatic, but also recognize the influence of marketing and adaptation interest that favor a vivid, definitive storyline [4] [1] [5]. For critical study, pair Macintyre with primary documents or academic works (not present in these sources) to separate participant memory and authorial framing from archival record.

In short: Macintyre’s The Spy and the Traitor is the dominant popular account of Gordievsky’s double life—celebrated for dramatic force and reported access to key figures—while readers who want documentary confirmation beyond interviews should note that the provided reporting emphasizes personal testimony and publisher framing [1] [7] [4].
