Pavel is Monika Maron’s grandfather. But she only remembers him in black and white. He left his children behind in Berlin when he was deported to his native Poland. Monika can only recall pictures of her grandparents, black-and-white photographs: Pavel perished in a concentration camp. And then, as a grown-up with a son of her own, researching a documentary for German television, Monika discovers letters which her grandfather wrote to Monika’s mother, Hella. The astonishing fact is that Hella does not remember Pavel’s letters.
