"Captain Feng, Miss Qin, have you had dinner?" Su Nanzhi pointed to the dishes in front of her and said, "If not, would you like to join us? There's plenty of food today."
Captain Feng: "..."
The little girl's warm hospitality should also be contingent on the situation.
"No, thank you," Captain Feng said in a deep voice, "Miss Su, do you know why we have come to see you?"
Su Nanzhi displayed a puzzled face, "Is it about my brother's case?"
Captain Feng shook his head: "The suspect in your brother's case, Liu Hang, has implicated someone else, claiming he was taking the blame for someone. However, we've hit a snag with the case and probably won't resolve it for another couple of days. We've come to you regarding a different matter."
Sometimes, the most annoying part of an investigation is dealing with wealth.
The idea that 'money can make the devil turn the millstone' seems to be an eternal fallacy, too.
