A key figure in the politics and literature of Argentina, Rodolfo Walsh wrote his iconic Letter to my Friends in December 1976, recounting the murder of his daughter Victoria by the military dictatorship. Just a few months later, he was killed in a shoot-out - just one of the Junta's many thousands of victims. What if this complex figure - a father, militant, and writer who delved the regime's political crimes - had also sought to reveal the truth of his own daughter's death? Elsa Drucaroff's imagining of Rodolfo Walsh undertaking the most personal investigation of his life is an electrifying, suspense-filled drama in which love and life decisions are inseparable from political convictions as he investigates the mystery of what happened to his own daughter. The head of intelligence for Montoneros, a clandestine Peronist organisation co-ordinating armed resistance against the dictatorship, Rodolfo Walsh was also a prolific writer and journalist, seen as the forerunner of the true crime genre with his 1957 book Operation Massacre. What if beneath the surface of his Letter to my Friends lay a gripping story lost to history?
