The plot progresses depending on the perspective of different characters: the old lady especially, but also some of his relatives, his main doctor and various representatives of the State. The look of the old lady in the direction of a tip enigmatic child, evanescent, almost nonexistent. The author distills gradually its indices with consummate skill. She passed his reader by all inner states in which one can find, in real life, in the presence dune problematic situation, difficult to understand and interpret; because we simplique in this dramatic story that has nothing to do with an ordinary murder mystery. One of the main themes, the most obvious perhaps is the child maltreatment. But there are others: including old age, loneliness, and also the cold and inquisitive look that society puts it on people with these characteristics. This book is taking, upsetting, and printed in me a lasting trace.
