Nicolas Sarkozy's new book, A Prisoner's Diary, presents a colorful account of his brief time in the isolation wing of La Santé prison, following his sentencing for electoral misconduct. In just under three weeks, Sarkozy shares the realities of his confinement and his reflections on justice, politics, and personal bonds.

The memoir details his living conditions, including a small cell equipped with basic amenities but lacking a view, as well as his choice to exercise on a treadmill rather than in the prison yard, which he describes as more like a cage.
Reflecting on the human experience within the prison walls, Sarkozy also expresses gratitude towards the prison staff, who addressed him as Président.
He shares anecdotes, from sleepless nights plagued by a neighbor singing The Lion King's songs to the support of friends through written postcards.

Suffering from the stigma of his conviction, Sarkozy draws parallels between his situation and that of Alfred Dreyfus, a historical figure wronged by the justice system. Amidst his personal struggles, Sarkozy analyzes his relationships with contemporary political leaders, criticizing Emmanuel Macron's handling of his public dismissal and displaying unexpected appreciation towards Marine Le Pen's supportive comments.

A Prisoner's Diary emerges as not only a personal narrative but a commentary on political dynamics, urging readers to consider the complex interplay of power, justice, and public perception in France today.
