Sherlock Holmes’ earnest demeanour had so far convinced us that we all sat in silence, watching the animal intently, and expecting some startling effect.

I felt some reflection of his elation in my own mind, for I knew well that he would not depart so far from his usual austerity of demeanour unless there was good cause for exultation.
