read this excerpt from “incidents in the life of a slave girl.”

i went about my evening work with trembling steps. mr. flint twice called from his chamber door to inquire why the house was not locked up. i replied that i had not done my work. "you have had time enough to do it," said he. "take care how you answer me! "

i shut all the windows, locked all the doors, and went up to the third story, to wait till midnight. how long those hours seemed, and how fervently i prayed that god would not forsake me in this hour of utmost need! i was about to risk everything on the throw of a die; and if i failed, o what would become of me and my poor children? they would be made to suffer for my fault.

at half past twelve i stole softly down stairs. i stopped on the second floor, thinking i heard a noise. i felt my way down into the parlor, and looked out of the window. the night was so intensely dark that i could see nothing. i raised the window very softly and jumped out. large drops of rain were falling, and the darkness bewildered me. i dropped on my knees, and breathed a short prayer to god for guidance and protection. i groped my way to the road, and rushed towards the town with almost lightning speed.
