"I see. I see. Well, nothing will be easier to establish than whether he did or didn't. Whoever it was that left this record of an important part of his anatomy can be identified."
"If we can first catch him," I said.
"Surely. But it is an uncommon jaw,--narrow and prominent."
"Then I shall want to have you see my client Eugene Benbow. It will not be necessary for you to do anything more than to look at him, will it?"
"That will be enough. I can tell at a glance whether his jaw has this conformation. Or, find out who his dentist is, and I will get the information from him without his knowing it."
"Good. Now when can you go with me to the morgue? The sooner the better."
He made an appointment for later in the day, and I left him.
I hurried back to my office, for there were a number of things I had to see to before going to keep my appointment with Dr. Kenton. While I was yet a block away, I saw a young girl running down the street toward me. It did not occur to me that she was coming for me until she came near enough for me to recognize Jean Benbow. Then I hastened to meet her.
"What is it?" I asked anxiously.
"Come quick," she exclaimed--and even then I noticed that her swift run had not taken her breath away. "There's another one here to look after."
