Thanks so much for pointing out that possible error. It’s helpful when people notify us of something that looks suspicious, and we appreciate your letting us know about what you found, Crystal!
In this case, the closing quotation mark was left off to signify that Sherlock Holmes continued talking after the sentence given. There is a note in the corresponding Using Language Well lesson (student book) that says:
“There is no closing quotation mark because Holmes continues to talk; the exercise stops before you can see the rest of what he said. Read the book to find out the rest.”
Hopefully, the student will be intrigued! 🙂
