Lucasfilm As locked-room mysteries go, this one was a doozy. A famous Christian relic disappeared from a locked vault beneath the bomb-blasted streets of Nuremberg, just as the Second World War was ending and the famous trials of the Nazi elite were set to begin. The Holy Lance, or Spear of Destiny, was the iron pilum used by the Roman legionnaire Longinus to pierce Christ’s side as he hung on the cross, to see if he had died.
