“Bannister was very much upset by the incident. He had nearly fainted when we found that the papers had undoubtedly been tampered with. I gave him a little brandy and left him collapsed in a chair, while I made a most careful examination of the room. I soon saw that the intruder had left other traces of his presence besides the rumpled papers. On the table in the window were several shreds from a pencil which had been sharpened. A broken tip of lead was lying there also. Evidently the rascal had copied the paper in a great hurry, had broken his pencil, and had been compelled to put a fresh point to it.”
“Excellent!” said Holmes, who was recovering his good-humour as his attention became more engrossed by the case. “Fortune has been your friend.”
“This was not all. I have a new writing-table with a fine surface of red leather. I am prepared to swear, and so is Bannister, that it was smooth and unstained. Now I found a clean cut in it about three inches long—not a mere scratch, but a positive cut. Not only this, but on the table I found a small ball of black dough or clay, with specks of something which looks like sawdust in it. I am convinced that these marks were left by the man who rifled the papers. There were no footmarks and no other evidence as to his identity. I was at my wit’s end, when suddenly the happy thought occurred to me that you were in the town, and I came straight round to put the matter into your hands. Do help me, Mr. Holmes. You see my dilemma. Either I must find the man or else the examination must be postponed until fresh papers are prepared, and since this cannot be done without explanation, there will ensue a hideous scandal, which will throw a cloud not only on the college, but on the university. Above all things, I desire to settle the matter quietly and discreetly.”
