In the Jerusalem of 1945, he’s known as Yossi: a shrewd, agreeable taxi driver with grade-school Hebrew and fledgling English, ferrying tourists around the Old City in a black Peugeot (not his), showing them the Tower of David and the Jaffa Gate, selling them extra film and gratefully accepting their gratuities. Back in his native Latvia, though, he was Brand, an apt name for a Jew branded by loss.
