Passage: Adele and Frank fall in love and plan to escape to Canada with Henry, packing the car and cleaning out the house. Meanwhile, Henry develops a friendship with a mature girl named Eleanor, and goes to see her one more time before they leave. She manipulates him into thinking Adele and Frank are going to abandon him and he accidentally reveals Frank's past. Adele assures Henry she would never leave him.  The morning they are going to leave, Henry takes a note to his father's house and leaves it in his mailbox. While he is walking home, a policeman offers to drive him home, and Henry accepts. The policeman is suspicious of the packed car and nearly-empty house, but eventually leaves. Adele goes to the bank to get all the money out of her account, and the bank staff, too, are suspicious.  While Adele is gone, the neighbor comes over and speaks to Frank. She, too, is suspicious of who he may be. Henry's father finds the note that Henry left, and calls the house. Before Adele, Frank, and Henry can escape, they hear police sirens approaching.  Frank ties Henry and Adele up before he goes out to surrender, so that they won't be charged with harboring a fugitive.  It is not revealed who called the police to report Frank's presence at the house. Adele wants to plead in Frank's case but is warned by the prosecutor himself that if she does, Henry might be taken away from her. She writes letters to Frank but to protect her he returns them all unopened.

Question: Who does Frank restrain?
Henry and Adele
