Lev Raphael, a child of survivors, clearly knows this well. His new novel, "The German Money," tries to take on some of the questions that those who inherit the Holocaust must face. Raphael is also a mystery writer, so he is not only interested in recovering the past, but also in solving its mysteries. Because, as Faulkner implied, the past is always a mystery to us. We can never really know its truths. That's why it cannot die. There is too much for us to figure out.
