An Escape from Brigands

Father Louis Manaci, a zealous missionary, had great devotion to the Souls in Purgatory. He found himself obliged to set out on a dangerous journey, but confidently asked the Holy Souls to protect him in the dangers that he was likely to meet with. His road lay through a vast desert, which he knew to be infested with brigands. While plodding along, saying the Rosary for the Holy Souls, what was not his surprise, on looking around, but to find himself surrounded by a bodyguard, as it were, of blessed spirits. Soon he discovered the reason. He had fallen into an ambuscade of brigands, but the Holy Souls at once surrounded him and drove off the miscreants, who sought his life. The Holy Souls did not abandon him until he was well out of danger.
