how does Joel describe him encounter with Mary Dempster?

Surgeoner invites Dunstan to his mission. Dunstan accepts, and there learns how Joel was changed by his encounter with Mrs. Dempster. Moved by the woman's unconditional love - he had planned to rape her, but did not have to because she wanted to alleviate his suffering - he changed his life and now dedicates it to the homeless. Dunstan recognizes this event as Mary Dempster’s third miracle, which is the final one required for official recognition as a saint.
