your poor friend Mason, Mr. Potswood, to-night. This room has been searched for papers before we began, and papers have been burnt. In the search this drawer was opened—containing, as you see, nothing but a supply of new headed note-paper. The note-paper was hastily lifted to see if anything else lay beneath, and here, on the bottom sheet, these finger-marks were left in that same adhesive, freely marking red—a sort of stuff that sticks to and marks whatever it touches. The hand that lifted that paper was the hand that impressed that ghastly mark; and the hand that left its print on this black varnish was Mr. Everard Myatt's! Now compare the two!"
Plummer had snatched the lens, and was narrowly comparing the marks ere Hewitt had well finished speaking.
"They are!" he cried, as the rector bent excitedly over him. "They are the same! See—forefinger and middle finger—the same, every line!"
"I needn't tell you," pursued Hewitt, "certainly I needn't tell Plummer, that that is the most certain and scientific method of identification known. The police know that—and use it. But now there is some more. You saw me take that charred paper from the fire. Sometimes words may be read on charred paper—it depends on the paper and the ink.
