Task: Question Generation
Input (English): Passage: After busting a human trafficking ring led by Sheriff Wood, Jack Reacher returns to his old military headquarters to meet Major Susan Turner, whom he has been working with during his travels and has become his closest friend – only to learn from Colonel Sam Morgan that Turner has been accused of espionage and detained.
Turner's attorney, Colonel Bob Moorcroft, reveals that there is evidence that Turner is involved in the murders of two soldiers in Afghanistan, but Reacher believes she is being framed. Moorcroft also reveals an old acquaintance of Reacher, Candice Dutton, has filed a paternity suit against him, claiming he is the biological father of her 15-year-old daughter, Samantha Dutton. Reacher tries to reach out to Samantha, but she rebuffs him, believing he is after her biological mother due to her past as a prostitute.
Moorcroft is later killed by an unknown assassin known as the Hunter. Reacher is framed for Moorcroft's murder and arrested and transported to the prison where Turner is being detained. Two hitmen arrive to kill her, but Reacher neutralizes them, rescues her and they escape to Morgan's house, having deduced he is involved in the conspiracy, to extract information. After they leave, the Hunter, revealed to be working with Morgan, kills Morgan and frames Reacher which he learns about from a friend, Sergeant Leach, when he asks her to investigate a military contractor.
Reacher and Turner uncover surveillance pictures of Samantha and surmise she is in danger, arriving at her home to find her foster parents dead and Samantha hiding in the kitchen. Reacher and Turner decide to escort Samantha to Turner's old private school for protection, but discover that she has her mobile phone with her and that the enemy probably knows exactly where they are. They discard the phone and make a quick exit, during which Samantha steals a backpack from one of the students to use the credit cards.
Output (English): What is the last name of the person that lets Reacher know that someone is filing a paternity suit agaist him?
