Angrily I threw the papers on the desk. Nonsense, nonsense, nonsense! Again nothing but nonsense! I am fed up with it, I murmured to myself. It means nothing! It tells nothing about Peter's disappearance. It gives no clue!
“It does,” a voice said behind my back, making me turn sharply. It was Mr. Pearson. I didn't hear him come in. “It does,” he repeated, stepped to the bookcase, taking out a book. “It does if you keep in mind that all the questions are asked by Isabelle. Go on reading, you'll find the answer.” And again he disappeared.
