"But what will you do?"

"We shall spend the night in your room, and we shall investigate the cause of this noise which has disturbed you."

"I believe, Mr. Holmes, that you have already made up your mind," said Miss Stoner, putting her hand upon Holmes' sleeve. For pity's sake, tell me what caused my sister's death."

"I should prefer to have clearer evidence before I speak."

"You can at least tell me if my own idea is correct. I think she died from some sudden fright."

"No, I do not think so. I think that there was probably something more real. And now, Miss Stoner, we must leave you. If Dr. Roylott returns and sees us, our journey would be for nothing. Good-bye, and be brave. If you will do what I have told you, you can be sure that we shall soon drive away the dangers that threaten you."
