The earth outside the tiny village of Treblinka, in eastern Poland, still bears traces of the death camp the Nazis built there in 1942. Close to 925,000 Jews were slaughtered at Treblinka, making it the second-largest Jewish killing field in the world after Auschwitz. On a sad, wet day in November, I wandered close to where Germans had burned the bodies of those murdered in the gas chambers nearby. At my feet on the damp ground, among the pebbles, I saw tiny white specks. They were small pieces of bones that still rise to the surface of the tainted earth of Treblinka after the rain.
