Frankenstein Chapter 14
Having gained the ability to understand language and even read, the monster learned the history of the cottagers and the Arabian woman. He offered Frankenstein copies of the letters of Felix and Safie as proof of his honesty. At one time, De Lacey, the old man, was a wealthy Parisian, until Felix learned of the unjust imprisonment of Muhammadan, Safie's father. Felix set out to free the man condemned for his religion and wealth, and that's how he met Safie and fell in love with her. Muhammadan, uncertain of Felix's loyalty to his cause, promised Safie's hand in marriage upon his escape from prison to ensure that Felix wouldn't forget about him. Felix, expecting to marry Safie, waited with Muhammadan in Italy until the escaped prisoner could get to Turkey safely. Safie did not want to return to Turkey because of the restrictions on the religion and society of women there. Her late mother, a Christian Arab freed from slavery by marriage to Muhammadan, had taught Safie independence and she wanted to stay in France with Felix, but her father had other plans. Muhammadan wanted Safie to return with him, but he kept his plans a secret so that Felix wouldn't turn him over to the French government.
Meanwhile, the French government discovered the De Lacey's connection with Muhammadan's escape, and De Lacey and Agatha were imprisoned. Felix heard the news and returned home immediately expecting that Muhammadan would leave for Turkey as soon as he could, but that Safie would wait in Italy for Felix to come back for her. When Felix and his family were exiled to Germany, Muhammadan told Safie to forget Felix, and then, fearing he would soon be discovered, he left for Turkey. Safie was to wait in Italy to gather his possessions and then travel to Turkey, but she left for Germany to find Felix instead.
