"I do not understand why this is a problem," says the book thief. "Because she can't help them but she hasn't come back!" Jakin interrupts. "It means she's been arrested." Mina sniffs miserably. "They want something from her," Jakin goes on. "She had a High One coin that didn't come from the museums. So I think they want to know how she got it."
