The author recounts his arrest and prolonged incarceration for political involvement, tracing successive detentions, a trial, and transfer to a remote fortress where he endures severe isolation and harsh conditions. The narrative interweaves concrete details of daily prison life—rigid routine, deprivation, and solidarity with fellow inmates—with reflective passages on memory, moral endurance, faith, and the sustaining influence of books and friendships. Attention centers on small human gestures and the slow passage of years, leading to a commuted sentence and eventual release, followed by a withdrawn return to literary pursuits and contemplation of freedom and suffering.
