The 115 cardinals who will select the next pope are taking oaths of secrecy as they prepare to begin their discussions.
Moving in solemn procession and chanting prayers as they walked, the cardinal-electors entered the Sistine Chapel after a pre-conclave Mass at St. Peter's Basilica.

Black smoke, no pope. White smoke, success.
