A surprisingly tender and philosophically deep book by E.-E. Schmitt, part of his “Cycle of the Invisible,” is disguised as an outwardly simple story about a boy abandoned by his father and suffering from loneliness. He lives in Paris on Blue Street, which has not been blue for a long time, and buys canned food for dinner from a local Arab, who is not an Arab at all. What is real here? Growing up, friendship, encountering the world of another religion, the unique melody of life.
