Highlights the sophistication of the deception and the expertise of Farr.
“It’s simple! I got hold of a man whose prints I knew weren’t in any police gallery—I didn’t want any slip up there—and took his prints and put them on a copper plate, using the ordinary photoengraving process, but etching it pretty deep. Then I coated Clane’s fingers with gelatin—just enough to cover all his markings—and pressed them against the plates.”
