From the Books: "Worse yet, from my perspective, was the simple fact that he returned home every night to his grandmother. She apparently clucked over him like Zoe clucked over her family, and me for that matter.
Once we made that connection, we started trailing the grandmother, too, because I had run into her before. She was the cook at the Plucked Owl, a coincidence too striking for us not to investigate. The most interesting thing we learned about her was the fact that everyone in the neighborhood loved her revithia, a chickpea soup common in the Great City." - TEOAD, p. 329-30
