"Was there anything peculiar about the formation of his jaw, do you remember? Any irregularity, for instance?"
The dentist smiled. "Yes. Decided irregularity. His jaw was peculiarly long and narrow, and the teeth, which were large, were crowded. On both sides the upper teeth formed a V."
"Like this?" I asked, taking the model which Dr. Kenton had made for me from my pocket.
"Exactly like that," he said, after examining it critically. "Wasn't this made from his mouth?"
"That is what I want to ascertain."
"It would be extraordinary to find two persons with the same marked peculiarity," he said thoughtfully.
"Would that peculiarity be enough to establish the man's identity?" I asked.
"Perhaps not. But I could identify Diavolo positively and beyond question, if that is what you mean. There were other distinguishing marks. The first lower left molar was gone, and replaced by a bridge, for instance. And the second molars in the upper jaw had both been extracted,--probably to relieve the crowding. The conformation was unmistakable, and very unusual."
"Then if I ever get my hands on Diavolo, you can identify him, regardless of grease paint and wig?"
"Unquestionably."
