THE DULTSEV AND THE RUSSIAN SPY FACTORY IN LATIN AMERICA (OS DULTSEV E A FÁBRICA DE ESPIÕES RUSSOS NA AMÉRICA LATINA)
This is the true story of a very “normal” Argentine family of Russian spies. They created their identity in Buenos Aires. Their two children were born there and lived undercover until the family was found by the Police while operating from Slovenia. The children first learned that their parents were Russian spies during a flight to Moscow after a prisoner exchange between Russia and the West in 2024, when Vladimir Putin welcomed their arrival at the airport with a friendly “buenas noches” - good evening in Spanish. A story that reveals a true industry of “illegal agents” that the Kremlin set up in Latin America with dozens of former KGB agents obtaining new identities and passports in the continent to continue operating around the world
A fascinating book that mixes and combines intrigue, suspense, and recent world history. The Netflix series “The Americans” becomes reality. Russian spies are among us; they may even be your friendly neighbors with their adorable children, who are completely unaware of their parents’ true identities. Publication/Status: To be published by Europa-América (Portugal) in 2026. Film rights optioned by RT Features.
BERLINER - THE AVENGER OF TREBLINKA (BERLINER - EL VINGADOR DE TREBLINKA)
At the Treblinka concentration camp, 850,000 Jews perished, while only one Nazi was killed—by Polish-Argentine Meir Berliner, who became a hero of the resistance. However, Berliner had a dark past in Argentina. Journalist and war correspondent Gustavo Sierra spent ten years investigating Berliner’s life, unraveling a complex narrative that reveals the duality of human nature: we can all be both victims and victimizers, heroes and villains.
Berliner was part of a Jewish-Polish mafia that trafficked Polish girls, many of them minors, for prostitution in brothels across Buenos Aires, Rosario, Montevideo, and Rio de Janeiro. After finding love and having a daughter, he attempted to escape this life, but international law enforcement pursued him. He fled from Rosario to Uruguay and then to Brazil, ultimately returning to war-torn Europe. Captured, he was confined in the Warsaw ghetto and later sent to Treblinka under the Final Solution. His wife and daughter perished in the gas chambers, while he was forced into labor due to his physical strength. He attempted to organize an uprising but failed to garner support, leading him to plan his final act of revenge.
