Tunnel to Canto Grande tells the dramatic story of how the Peruvian Tupac Amuru Revolutionary Movement (MRTA) tunneled into an "escape-proof" penitentiary, Canto Grande, to free forty-eight political prisoners on July 9, 1990. The prisoners escaped through the tunnel without a single casualty and eluded the authorities. Because of their world-wide reputation as writers of testimony, the authors, Alegría and Flakoll, were invited by MRTA leaders to write the exclusive story of the escape. At no small risk to their own safety, they spent a week in the most hunted for safe house in Lima, Peru, interviewing the participants in the project and the escapees. The resulting narrative is filled with suspense, drama, and humor.
