And the head of the American diplomatic corps (the nun was an American) assigns the investigation of the killing to one of his underlings, which leads the young man to investigate the Russicum, a center for the study of Russia within the Vatican city. And from there he finds himself caught up in an intrigue of international proportions, filled with agents and double agents, and ending with a revelation most unexpected.
