“I am setting off for French Guiana, on a journey of mourning and redemption. Along the way, I will write a letter to Yann, my childhood friend, who is imprisoned for a crime he committed on September 14, 1997. I want to break the silence that the prison visiting room has trapped us in. At the heart of our powerful friendship lies an act that is irreversible and unforgivable. I cannot erase it.”
