Even as we pulled up, a grizzled head appeared at the front window, and we were aware of a pair of keen eyes from under shaggy brows which surveyed us through large horn glasses. A moment later we were actually in his sanctum, and the mysterious scientist, whose vagaries had brought us from London, was standing before us. There was certainly no sign of eccentricity either in his manner or appearance, for he was a portly, large-featured man, grave, tall, and frock-coated, with the dignity of bearing which a lecturer needs. His eyes were his most remarkable feature, keen, observant, and clever to the verge of cunning.
He looked at our cards. “Pray sit down, gentlemen. What can I do for you?”
Mr. Holmes smiled amiably.
“It was the question which I was about to put to you, Professor.”
“To me, sir!”
“Possibly there is some mistake. I heard through a second person that Professor Presbury of Camford had need of my services.”
“Oh, indeed!” It seemed to me that there was a malicious sparkle in the intense gray eyes. “You heard that, did you? May I ask the name of your informant?”
“I am sorry, Professor, but the matter was rather confidential. If I have made a mistake there is no harm done. I can only express my regret.”
“Not at all. I should wish to go further into this matter. It interests me. Have you any scrap of writing, any letter or telegram, to bear out your assertion?”
“No, I have not.”
“I presume that you do not go so far as to assert that I summoned you?”
“I would rather answer no questions,” said Holmes.
“No, I dare say not,” said the professor with asperity. “ However, that particular one can be answered very easily without your aid.”
He walked across the room to the bell. Our London friend Mr. Bennett, answered the call.
“Come in, Mr. Bennett. These two gentlemen have come from London under the impression that they have been summoned. You handle all my correspondence. Have you a note of anything going to a person named Holmes?”
“No, sir,” Bennett answered with a flush.
“That is conclusive,” said the professor, glaring angrily at my companion. “Now, sir” — he leaned forward with his two hands upon the table —” it seems to me that your position is a very questionable one.”
Holmes shrugged his shoulders.
“I can only repeat that I am sorry that we have made a needless intrusion.”
“Hardly enough, Mr. Holmes!” the old man cried in a high screaming voice, with extraordinary malignancy upon his face. He got between us and the door as he spoke, and he shook his two hands at us with furious passion. “You can hardly get out of it so easily as that.” His face was convulsed, and he grinned and gibbered at us in his senseless rage. I am convinced that we should have had to fight our way out of the room if Mr. Bennett had not intervened.
“My dear Professor,” he cried, “consider your position! Consider the scandal at the university! Mr. Holmes is a wellknown man. You cannot possibly treat him with such discourtesy.”
Sulkily our host — if I may call him so — cleared the path to the door. We were glad to find ourselves outside the house and in the quiet of the tree-lined drive. Holmes seemed great!y amused by the episode.
“Our learned friend’s nerves are somewhat out of order,” said he. “Perhaps our intrusion was a little crude, and yet we have gained that personal contact which I desired. But, dear me, Watson, he is surely at our heels. The villain still pursues us.”
There were the sounds of running feet behind, but it was, to my relief, not the formidable professor but his assistant who appeared round the curve of the drive. He came panting up to us.
“I am so sorry, Mr. Holmes. I wished to apologize.”
“My dear sir, there is no need. It is all in the way of professional experience.”
“I have never seen him in a more dangerous mood. But he grows more sinister. You can understand now why his daughter and I are alarmed. And yet his mind is perfectly clear.”
“Too clear!” said Holmes. “That was my miscalculation. It is evident that his memory is much more reliable than I had thought.
