 A bag of marbles. You will love it. It's the Paris Roundup. Through the eyes of children. And a Jewish barber and his sons and wife have to flee the great Paris Roundup. And I won't say anything more about it. I don't want to give anything away in Daniel Silva's new novel, A Death in Cornwall, but part of it is tied to the great Paris Roundup by the Nazis of the Jews of Paris in 1942 on one day, basically, right? 18,000 people?
