of them trivial in themselves but all tending in the same direction, I could not disguise from myself that even if Holmes’s explanation were incorrect the true theory must be equally outré and startling.

At three o’clock on the afternoon there was a loud peal at the bell, an authoritative voice in the hall, and, to my surprise, no less a person than Mr. Athelney Jones was shown up to me. Very different was he, however, from the brusque and masterful professor of common sense who had taken over the case so confidently at Upper Norwood. His expression was downcast, and his bearing meek and even apologetic.

“Good-day, sir; good-day,” said he. “Mr. Sherlock Holmes is out, I understand.”

“Yes, and I cannot be sure when he will be back. But perhaps you would care to wait. Take that chair and try one of these cigars.”

“Thank you; I don’t mind if I do,” said he, mopping his face with a red bandanna handkerchief.

“And a whisky and soda?”

“Well, half a glass. It is very hot for the time of year, and I have had a good deal to worry and try me. You know my theory about this Norwood case?”

“I remember that you expressed one.”

“Well, I have been obliged to reconsider it. I had my net drawn tightly round Mr. Sholto, sir, when pop he went through a hole in the middle of it. He was able to prove an alibi which could not be shaken. From the time that he left his brother’s room he was never out of sight of someone or other. So it could not be he who climbed over roofs and through trapdoors. It’s a very dark case, and my professional credit is at stake. I should be very glad of a little assistance.”

“We all need help sometimes,” said I.

“Your friend, Mr. Sherlock Holmes, is a wonderful man, sir,” said he in a husky and confidential voice. “He’s a man who is not to be beat. I have known that young man go into a good many cases, but I never saw the case yet that he could not throw a light upon. He is irregular in his methods and a little quick perhaps in jumping at theories, but, on the whole, I think he would have made a most promising officer, and I don’t care who knows it. I have had a wire from him this morning, by which I understand that he has got some clue to this Sholto business. Here is his message.”

He took the telegram out of his pocket and handed it to me. It was dated from Poplar at twelve o’clock.

Go to Baker Street at once [it said]. If I have not returned, wait for me. I am close on the track of the Sholto gang. You can come with us to-night if you want to be in at the finish.

“This sounds well. He has evidently picked up the scent again,” said I.

“Ah, then he has been at fault too,” exclaimed Jones with evident satisfaction. “Even the best of us are thrown off sometimes. Of course this may prove to be a false alarm but it is my duty as an officer of the law to allow no chance to slip. But there is someone at the door. Perhaps this is he.”

A heavy step was heard ascending the stair, with a great wheezing and rattling as from a man who was sorely put to it for breath. Once or twice he stopped, as though the climb were too much for him, but at last he made his way to our door and entered. His appearance corresponded to the sounds which we had heard. He was an aged man, clad in seafaring garb, with an old pea-jacket buttoned up to his throat. His back was bowed, his knees were shaky, and his breathing was painfully asthmatic. As he leaned upon a thick oaken cudgel his shoulders heaved in the effort to draw the air into his lungs. He had a coloured scarf round his chin, and I could see little of his face save a pair of keen dark eyes,
