“Can you tell me anything else about them?”

“A great deal. From the mud on the boots of the tall one I perceive that he comes from South Norwood. The other is as obviously a Scotch author.”

“How can you tell that?”

“He is carrying in his pocket a book called (I clearly see) ‘Auld Licht Something.’ Would any one but the author be likely to carry about a book with such a title?”

I had to confess that this was improbable.

It was now evident that the two men (if such they can be called) were seeking our lodgings. I have said (often) that my friend Holmes seldom gave way to emotion of any kind, but he now turned livid with passion. Presently this gave place to a strange look of triumph.

“Watson,” he said, “that big fellow has for years taken the credit for my most remarkable doings, but at last I have him—at last!”

Up I went to the ceiling, and when I returned the strangers were in the room.

“I perceive, gentlemen,” said Mr. Sherlock Holmes, “that you are at present afflicted by an extraordinary novelty.”

The handsomer of our visitors asked in amazement how he knew this, but the big one only scowled.
