"A rude fellow," said our guide, flushing with anger as we withdrew down the stair. "Of course, he did not realize that it was I who was knocking, but none the less his conduct was very uncourteous, and, indeed, under the circumstances rather suspicious."
Holmes's response was a curious one.
"Can you tell me his exact height?" he asked.
"Really, Mr. Holmes, I cannot undertake to say. He is taller than the Indian, not so tall as Gilchrist. I suppose five foot six would be about it."
"That is very important," said Holmes. "And now, Mr. Soames, I wish you good-night."
Our guide cried aloud in his astonishment and dismay. "Good gracious, Mr. Holmes, you are surely not going to leave me in this abrupt fashion! You don't seem to realize the position. To-morrow is the examination. I must take some definite action to-night. I cannot allow the examination to be held if one of the papers has been tampered with. The situation must be faced."
"You must leave it as it is. I shall drop round early to-morrow morning and chat the matter over. It is possible that I may be in a position then to indicate some course of action. Meanwhile you change nothing -- nothing at all."
"Very good, Mr. Holmes."
"You can be perfectly easy in your mind. We shall certainly find some way out of your difficulties. I will take the black clay with me, also the pencil cuttings. Good-bye."
When we were out in the darkness of the quadrangle we again looked up at the windows. The Indian still paced his room. The others were invisible.
"Well, Watson, what do you think of it?" Holmes asked, as we came out into the main street. "Quite a little parlour game -- sort of three-card trick, is it not? There are your three men. It must be one of them. You take your choice. Which is yours?"
"The foul-mouthed fellow at the top. He is the one with the worst record. And yet that Indian was a sly fellow also. Why should he be pacing his room all the time?"
"There is nothing in that. Many men do it when they are trying to learn anything by heart."
"He looked at us in a queer way."
"So would you if a flock of strangers came in on you when you were preparing for an examination next day, and every moment was of value. No, I see nothing in that. Pencils, too, and knives -- all was satisfactory. But that fellow DOES puzzle me."
"Who?"
"Why, Bannister, the servant. What's his game in the matter?"
"He impressed me as being a perfectly honest man."
"So he did me. That's the puzzling part. Why should a perfectly honest man -- well, well, here's a large stationer's. We shall begin our researches here."
There were only four stationers of any consequence in the town, and at each Holmes produced his pencil chips and bid high for a duplicate. All were agreed that one could be ordered, but that it was not a usual size of pencil and that it was seldom kept in stock. My friend did not appear to be depressed by his failure, but shrugged his shoulders in half-humorous resignation.
"No good, my dear Watson. This, the best and only final clue, has run to nothing. But, indeed, I have little doubt that we can build up a sufficient case without it. By Jove! my dear fellow, it is nearly nine, and the landlady babbled of green peas at seven-thirty. What with your eternal tobacco, Watson, and your irregularity at meals, I expect that you will get notice to quit and that I shall share your downfall -- not, however, before we have solved the problem of the nervous tutor, the careless servant, and the three enterprising students."
