Radio Replies From The Golden Age of Catholic Apologetics
Father Carty contacted Father Rumble and they collaborated and produced an American version of Radio Replies and it went on to become so successful they published 3 volumes. Though the two priests never actually met in real life, their apologetic work continues to be available in book form as well as online for free.
