The Prisoner of Heaven

The Series’ Political Reckoning

The first two Cemetery of Forgotten Books novels are gothic mysteries set against the shadow of Franco’s Spain — the political reality is present as atmosphere and context, shaping the characters’ lives and the city’s character, but it operates mostly as backdrop. The Prisoner of Heaven changes this. In the shortest novel of the series, Zafón turns to face what his Barcelona’s shadows actually contain: the specific, bureaucratic, systematic brutality of Franco’s prisons and the fate of the Republican generation.

The novel returns to Daniel Sempere’s bookshop in 1957 Barcelona, where a mysterious figure arrives and sets in motion the revelation of Fermín Romero de Torres’s past — his real identity and what happened to him in Montjuïc Castle during the early years of the Franco regime. Fermín, the irrepressible, polyglot, philosophically extravagant bookshop assistant who has been the series’ most beloved supporting character, turns out to have a history of extraordinary darkness.

Montjuïc: The Castle Above the City

Montjuïc Castle, which sits above Barcelona’s port and can be seen from much of the city, served as a political prison and execution site throughout the Franco period. Zafón uses the castle with the same architectural intelligence he brings to the rest of Barcelona — it is a building whose physical fact (its visibility, its position above the city it surveills) encodes its political meaning. The prison sequences are the most directly harrowing writing in the series: cold, specific, stripped of the gothic atmosphere that has characterized the earlier books.

What Fermín witnessed and survived there — the mechanisms of political terror, the destruction of men who had committed the crime of holding the wrong ideas — gives the series’ mysteries a new moral grounding. The Cemetery of Forgotten Books, it becomes clear, is not merely a romantic institution for bibliophiles but a place of genuine resistance, a counter-archive to the official forgetting that Franco’s regime required.

Fermín’s Voice

The novel’s greatest achievement is giving Fermín’s ironic, digressive, encyclopaedic way of speaking a history that makes it comprehensible as something other than comic eccentricity. His wit is a survival strategy, developed under conditions that would have destroyed a person without the capacity to maintain ironic distance from horror. His love of language — of the specific, the precise, the elaborately expressed — is the resistance of someone who has seen what happens when language is controlled by power.

At 288 pages, The Prisoner of Heaven is an interlude in the series as much as a complete novel — readers who have not read The Shadow of the Wind will find it requires that context. But for those who have followed the series, it is its emotional centre: the book that explains why these mysteries matter, and why the city that contains them is worth loving and grieving over.

Our rating: 4.1/5 — The shortest and most politically direct Cemetery of Forgotten Books novel, The Prisoner of Heaven grounds gothic atmosphere in historical fact and gives its most beloved character the backstory he deserves.
