“When you say that you studied fingerprinting, what do you mean?” the deputy district attorney asked.

“I mean that I took a regular course in fingerprinting and all of its phases, learned the methods of indexing and filing fingerprints, of identifying men from fingerprints, of developing what are known as latent fingerprints, photographing them, checking and comparing them.”

“I call your attention to the photograph which has been identified by the witness who preceded you as that of Morgan Eves and ask you if you have ever seen that man.

“I have.”

“Do you recognize him?”

“I do.”

“Who is he?”

“He’s James Whitly, also known as James Clerke.”

“Does he have a criminal record?”

Mason jumped to his feet, his manner that of one who is cornered and fighting desperately.
