I woke up in a strange room, as it seemed to me, and made my way out into the street in a sort of dazed way when you were absent.'
"'And I,' said the son, 'seeing my father pass the door of the waiting-room, naturally thought that the consultation had come to an end. It was not until we had reached home that I began to realize the true state of affairs.'
"'Well,' said I, laughing, 'there is no harm done except that you puzzled me terribly; so if you, sir, would kindly step into the waiting-room I shall be happy to continue our consultation which was brought to so abrupt an ending.'
"'For half an hour or so I discussed that old gentleman's symptoms with him, and then, having prescribed for him, I saw him go off upon the arm of his son.
"I have told you that Mr. Blessington generally chose this hour of the day for his exercise. He came in shortly afterwards and passed upstairs. An instant later I heard him running down, and he burst into my consulting-room like a man who is mad with panic.
"'Who has been in my room?' he cried.
"'No one,' said I.
"'It's a lie! He yelled. 'Come up and look!'
"I passed over the grossness of his language, as he seemed half out of his mind with fear. When I went upstairs with him he pointed to several footprints upon the light carpet.
"'D'you mean to say those are mine?' he cried.
"They were certainly very much larger than any which he could have made, and were evidently quite fresh. It rained hard this afternoon, as you know, and my patients were the only people who called. It must have been the case, then, that the man in the waiting-room had, for some unknown reason, while I was busy with the other, ascended to the room of my resident patient. Nothing has been touched or taken, but there were the footprints to prove that the intrusion was an undoubted fact.
"Mr. Blessington seemed more excited over the matter than I should have thought possible, though of course it was enough to disturb anybody's peace of mind. He actually sat crying in an arm-chair, and I could hardly get him to speak coherently. It was his suggestion that I should come round to you, and of course I at once saw the propriety of it, for certainly the incident is a very singular one, though he appears to completely overtake its importance. If you would only come back with me in my brougham, you would at least be able to soothe him, though I can hardly hope that you will be able to explain this remarkable occurrence."
Sherlock Holmes had listened to this long narrative with an intentness which showed me that his interest was keenly aroused. His face was as impassive as ever, but his lids had drooped more heavily over his eyes, and his smoke had curled up more thickly from his pipe to emphasize each curious episode in the doctor's tale. As our visitor concluded, Holmes sprang up without a word, handed me my hat, picked his own from the table, and followed Dr. Trevelyan to the door. Within a quarter of an hour we had been dropped at the door of the physician's residence in Brook Street, one of those sombre, flat-faced houses which one associates with a West-End practice. A small page admitted us, and we began at once to ascend the broad, well-carpeted stair.
But a singular interruption brought us to a standstill. The light at the top was suddenly whisked out, and from the darkness came a reedy, quivering voice.
"I have a pistol," it cried. "I give you my word that I'll fire if you come any nearer."
"This really grows outrageous, Mr. Blessington," cried Dr. Trevelyan.
"Oh, then it is you, doctor," said the voice, with a great heave of relief. "But those other gentlemen, are they what they pretend to be?"
We were conscious of a long scrutiny out of the darkness.
"Yes, yes, it's all right," said the voice at last. "You can come up, and I am sorry if my precautions have annoyed you."
He relit the stair gas as he spoke, and we saw before us a singular-looking man, whose appearance, as well as his voice, testified to his jangled nerves.
