"Aw, hell, it's a frame up. How can my finger prints be on--" he sprang to his feet. "I wasn't there, I tell you, I wasn't there." The last word ended in a scream. He stood tense, rigid and fell back into his chair. He took an ornate handkerchief from his pocket and wiped his palms. He passed the handkerchief over his face. Conners looked toward the men who had brought in the prisoner. He asked: "Got him booked?" "No, we're jest holdin' him." "Take him away and book him. Charge him with the murder of August Schurman." During the cross-examination, Professor Brierly had not once taken his eyes from the prisoner. He was staring at him with the intent absorption he gave to an interesting specimen under the microscope. As they were about to lead Smith away, Professor Brierly started forward. "Just a moment, Sergeant, before you take him away, I'd like to have an impression of his mouth, rather his teeth, his upper and lower teeth. If there is a dentist near by--" "His teeth, Professor. In the name of God what do you want with an impression of his teeth." The assistant district attorney injected himself into the proceedings: "District Attorney McCall, Sergeant, gave explicit orders that Professor Brierly be given every opportunity to make a complete examination; that he be afforded every facility--" "Oh, all right. We'll have some dentistry. Dan, go over across the street and ask Doc Harris to come over here with the material for takin' an impression. Step on it." When the impression had been taken, Professor Brierly said to the dentist: "Doctor, we should like to have a model of this right away, please. It is important." "It may not be a very good one, Professor, a stone model would be better, but it will take--" "Yes, I know, that will take too long. Speed is essential. It will be accurate enough. Hasten the setting, please, doctor." When the prisoner was taken away, the Sergeant turned to Professor Brierly; he said with gracious condescension: "I dunno what that impression is for, Professor, but I guess mebbe you know what you're doin'. But we got the man who bumped off Schurman, ain't we?" Professor Brierly took from his pocket an object that he showed to Conners: "Do you recognize this, Sergeant?" "Why, ain't this the apple with the teeth marks you found in Schurman's refrigerator? How could it keep like this?" "No, it is not, Sergeant; it is a replica. Take it into your hand and you will see it is not an apple. It is a model of the apple you saw. Alphonse Poller was the brilliant scientist who devised this method of taking impressions and making models. He called it 'moulage.' The word is used either as a verb or a noun. "Off hand, I should say that 'Fingy' Smith's teeth will not fit into the marks made in this apple. When the plaster model comes up here we will see." "What of it?" belligerently protested Conners. "We have his fingerprints; that's good enough for me. Someone else could have taken the bite in the apple."
