Problem: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke.

He believes they make wallets and handkerchiefs. 
Question: Who believes Fagin's gang make wallets and handkerchiefs?

Problem: Passage: In 1988, when Katrina "Kat" Connors was 17, her beautiful but mercurial mother, Eve, disappeared without a trace. The story weaves back-and-forth with flashbacks of Eve's past life and the present day.
In the flashbacks, Eve was a wild girl who gradually changed into a domesticated housewife after marrying Brock, an ordinary man who leads an uneventful life. While Kat explores her blossoming sexuality with her handsome but dim-witted neighbor and schoolmate, Phil, Eve struggles to deal with aging and quenching her youthful wildness. She tries to be sexy when Brock is away, even luring Phil's attention. After Eve disappears, Kat deals with her abandonment without much issue, occasionally releasing her own wild side, seducing the detective investigating her mother's disappearance. The film then jumps forward three years to the spring of 1991. On a break from college, Kat returns home and seems unfazed to learn that her father is in a relationship with a co-worker.
The detective Kat has been having an affair with informs her that Brock might have killed Eve after catching her cheating. Kat dismisses this theory, just like she did three years ago, but after mentioning the topic to her friends Beth and Mickey they tell her they suggested this same theory to her and she dismissed them as well. Kat suspects Phil of having slept with Eve and confronts him the night before she is to return to college, but Phil angrily rebuffs it and tells her that her father knows where her mother is. 
Question: What three people agree with the detective Kat's been having an affair with about what happened to her mother?
Solution:
Beth.
