This is the testimony of a man who stayed ten years without going out to street. He became a cat in the darkness, he was sat in front of a blank piece of paper, under a feeble light. That is the starting point of this book. It shows that necessity for a man who is obliged to live in silence and complete solitude and writes to feel that he is still alive. Although it is written in first person, Zapirain brings us to memory the personal experiences of a whole collective of people. He starts since the GAL most horrible age until nowadays.
