From the Guardian Unlimited:
The nun's identity is supposed to be a closely guarded secret, but a French newspaper named her last night as Marie-Simon-Pierre. On its website, Le Figaro said she was from a congregation near Aix-en-Provence, and worked in a maternity clinic in Paris. Slawomir Oder, a Polish cleric living in Rome who is the official advocate of John Paul's cause, declined to confirm or deny the report, saying he had been sworn to secrecy.
But, he had earlier told a press conference in Rome that the recovery of a French nun of "about 45 years old" was the main evidence that the late pope had miraculous powers. Among the thousands of documents in the dossier were two handwritten by the nun, he said. The first was written when she was in the grip of Parkinson's disease. Monsignor Oder said that in begging for the late Pope's intercession she had "written the name of John Paul II in an illegible hand, because of the illness".
He added: "On the morning of the miracle, however, the sister picked up a pen and wrote an entirely comprehensible letter." He said evidence from handwriting experts formed a crucial part of his file. The nun had also undergone a psychological examination. Monsignor Oder said she had been cured "two months after the Pope's death" in April 2005. "All the symptoms of her illness disappeared from one moment to the next," he said.
