Holmes held out a small chip with the letters NN and a space of clear wood after them.
“You see?”
“No, I fear that even now—”
“Watson, I have always done you an injustice. There are others. What could this NN be? It is at the end of a word. You are aware that Johann Faber is the most common maker’s name. Is it not clear that there is just as much of the pencil left as usually follows the Johann?” He held the small table sideways to the electric light. “I was hoping that if the paper on which he wrote was thin, some trace of it might come through upon this polished surface. No, I see nothing. I don’t think there is anything more to be learned here. Now for the central table. This small pellet is, I presume, the black, doughy mass you spoke of. Roughly pyramidal in shape and hollowed out, I perceive. As you say, there appear to be grains of sawdust in it. Dear me, this is very interesting. And the cut—a positive tear, I see. It began with a thin scratch and ended in a jagged hole. I am much indebted to you for directing my attention to this case, Mr. Soames. Where does that door lead to?”
“To my bedroom.”
“Have you been in it since your adventure?”
“No, I came straight away for you.”
“I should like to have a glance round. What a charming, old-fashioned room! Perhaps you will kindly wait a minute, until I have examined the floor. No, I see nothing. What about this curtain? You hang your clothes behind it. If anyone were forced to conceal himself in this room he must do it there, since the bed is too low and the wardrobe too shallow. No one there, I suppose?”
