Russia’s most powerful publishing house has been dragged into the Kremlin’s expanding war on content deemed subversive, with the detention of the chief executive of Eksmo and three other top managers on charges linked to the distribution of novels the state considers extremist propaganda. The arrests, which took place in Moscow on April 21, mark a sharp escalation in a campaign that began last year with the nationalisation of a video-game company and a confectionery group under the same article of the criminal code. Now the net has closed around a publisher that controls roughly a quarter of the country’s book market, sending a chill through an industry already reeling from five years of intensifying censorship.

The case centres on two young-adult novels — “Summer in a Pioneer Tie” and “What the Swallow is Silent About” — which explore same-sex relationships among adolescents. Both books were originally released by the niche imprint Popcorn Books, which Eksmo acquired before the 2023 law banning “propaganda of non-traditional sexual relations” took effect. Eksmo later asked retailers to destroy remaining copies, but investigators allege that thousands were still sold through what they describe as grey-market channels. The inquiry has been fuelled by testimony from Dmitry Protopopov, the former head of Popcorn Books, who struck a pre-trial deal with prosecutors and implicated his erstwhile colleagues at the larger publisher.

Viewed from Moscow, the operation is presented as a routine enforcement of legislation that designates the now-defunct “international LGBT movement” as an extremist organisation. Yet observers note that the same legal provision has been deployed to seize assets from unrelated sectors, raising questions about whether property confiscation is the unspoken objective. Analysts in London point to a broader pattern: the authorities are no longer targeting only small independent imprints but are now taking on the dominant player in Russian-language publishing, a move that risks paralysing the entire distribution chain. From Washington, the episode is likely to be seen as further evidence of a systematic assault on civil liberties, with the added twist that the accused publishers themselves had already attempted to comply with the law by withdrawing the titles.

The immediate future hinges on whether formal charges will be filed and what measure of restraint the court imposes. The detained executives — including the chief executive, the financial director, the deputy editor-in-chief, and the distribution director — remain in custody while the investigation continues. Forward-looking assessments in the industry suggest that even if the current case is resolved without imprisonment, the psychological damage is done. Publishers across Russia are now weighing whether to pre-emptively refuse any manuscript that could be interpreted as touching on sexuality, identity, or dissent. The state has signalled that no publisher, however large, is beyond reach, and the market for ideas is shrinking accordingly.
