"And I? Do you mean me to be present at an interview so painful, nay, so serious and so threatening? It would cut short every word you hope to hear. I—can not—"

"I have not asked you to. It is imperative that I should see Miss Camerden alone." (He could not call her Dorothy, either.) "I shall ask Gilbertine to accompany us, so that appearances may be preserved. I want you to be able to inform any one who approaches the door that you saw me go in there with Miss Murray."

"Then I am to stay in the hall?"

"If you will be so kind."

The clock struck three.

"It is very late," I exclaimed. "Why not wait till morning?"

"And have the whole house about our ears? No. Besides, some things will not keep an hour, a moment. I must hear what this young girl has to say in response to my questions. Remember, I am the owner of the flask whose contents killed the old woman!"

"You believe she died from swallowing that drop?"

"Absolutely."

I said no more, but hastened down stairs to do his bidding.
