But in this way she had had one or two glimpses into his mind, and she was really anxious about his mental state, and not happy about Alan either. She kept her shrewd old eyes open, and she began to see that Alan sometimes avoided being alone with his father. He seemed a little awkward with him, as though some shadow had risen up between them.

The unexpected is always delightful, and it is quite refreshing to have a few fingers blown off in a thrilling fashion, or even a head! Most people l[49]ose their heads in a much less interesting way, and under much less provocation. And as for smells, Alan, I worship them. In fact, I feel quite exhilarated when I have the smell of that adorable
