LOS DULTSEV, A VERY NORMAL ARGENTINIAN FAMILY OF RUSSIAN SPIES (LOS DULTSEV, UNA FAMILIA ARGENTINA MUY NORMAL DE ESPIAS RUSOS)
LOS DULTSEV tells the true story of a Russian spy couple who built their false nationality in Argentina, where their two children, Sofie (11) and Daniel (8), were born. The children were raised as Argentinians, speaking only Spanish with a Buenos Aires accent at home. Years later, Anna and Artem Dultsev were caught in Slovenia while coordinating a Russian espionage network across Europe. In 2024, they were released in the largest prisoner swap between Russia and the West and welcomed as heroes in Moscow by Vladimir Putin. Only on the plane, did their children find out that their parents were spies.

The case sparked global controversy over the sacrifice these Russian spies impose on their own children. Born and raised in a lie, they are stripped of their nationality, education, and friends without much justification. They suffer years of displacement and risk being blamed for the crimes committed by their parents, despite knowing nothing about them.

Several similar cases emerged years earlier in the United States when ten “illegal” spies (operating without official cover) were expelled along with their Canadian and American-born children.
Los Dultsev explores all these cases and their consequences—the details of their movements, the way “illegals” are trained, how they build their identities using deceased children’s records, their role for the Kremlin, their relationships with “enemy” agents from the FBI and CIA, and the heightened spy game that escalated with Russia’s invasion of Ukraine.

This investigation is based on secret documents from the judicial systems of Argentina, Slovenia, the United States, and Russia. A book of espionage, psychological drama, and recent history that raises unsettling questions: What will happen to these children, stripped of their childhood, nationality, and identity? Will they be able to forgive their parents for raising them in a lie? Will they follow in their footsteps and become spies themselves? Will they one day feel the need to return to the country where they were born and seek out their roots? Publication/Status: On submission.
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.
