Zane cast a look of admiration toward Noel. "Indeed you're the world- renowned detective, Noel Harrison! I will give you the cure after you do as I say. Have you heard of the Cole family of Ferropene? They have a son named Christopher. He is the only son out of three who hasn't appeared in public before turning eighteen. Even some in the Cole family haven't seen him before. Some say it's because of his frailty."
Zane continued, "The Cole family has hired five servants to take care of Christopher. Four of them took care of him until he left the Cole residence, but one of them resigned when he was fifteen. She claimed she had a serious illness and wanted to spend her final years in a nice place. I want you to investigate whether this servant is still alive. If she is, bring her to me. If she isn't, list down all the people who met Christopher before he turned eighteen."
Pausing for a moment, Noel exclaimed, "What brilliant thinking, Zane!"
