"Well, I happen to be clear to-morrow afternoon. If you would say a word to Mrs. Saunders it would be quite in order. By the way, who is your house-agent?"
Our client was amazed at the sudden question.
"Holloway and Steele, in the Edgware Road. But why?"
"I am a bit of an archæologist myself when it comes to houses," said Holmes, laughing. "I was wondering if this was Queen Anne or Georgian."
"Georgian, beyond doubt."
"Really. I should have thought a little earlier. However, it is easily ascertained. Well, good-bye, Mr. Garrideb, and may you have every success in your Birmingham journey."
The house-agent's was close by, but we found that it was closed for the day, so we made our way back to Baker Street. It was not till after dinner that Holmes reverted to the subject.
"Our little problem draws to a close," said he. "No doubt you have outlined the solution in your own mind."
"I can make neither head nor tail of it."
"The head is surely clear enough and the tail we should see to-morrow. Did you notice nothing curious about that advertisement?"
"I saw that the word 'plough' was misspelt."
"Oh, you did notice that, did you? Come, Watson, you improve all the time. Yes, it was bad English but good American. The printer had set it up as received. Then the buckboards. That is American also. And artesian wells are commoner with them than with us. It was a typical American advertisement, but purporting to be from an English firm. What do you make of that?"
