As I spoke I laid open on the table before me the transcription of which I spoke. Instantly the two men bent over it. When they looked up again, their countenances showed not excitement only but appreciation; and in the one minute of triumph which I then enjoyed, all that had wounded or disturbed me in the past was forgotten. “You are a man in a thousand,” was the major’s first enthusiastic comment; at which I was conscious of regretting, with very pardonable inconsistency, that Durbin had not returned in time to hear these words. The major now proposed that we should go at once to the old house. “A family secret like this does not crop up every day even in a city so full of surprises as Washington. We will hunt for the spring under the closet drawers and see what happens, eh? And on our way there”—here he turned to me “I should like to hear the particulars concerning the little clue just mentioned. By the way, Mr. Jeffrey’s interest in this old drawing is now explained. He knew its diabolical secret.” This was self-evident, and my heart was heavy for Miss Tuttle, who seemed to be so deep in her brother-in-law’s confidence. It grew still heavier when Durbin, joining us, added his incredulity to the air of suspicion assumed by the others. Through all the explanations I now entered into, I found myself inwardly repeating with somewhat forced iteration, “I will not believe her guilty under any circumstances. She carries the look of innocence, and innocent she must be proved, whatever the result may be to Francis Jeffrey.” To such an extent had I been influenced by the lofty expression which I had once surprised on her face. Had Mr. David Moore been sitting open-eyed behind his vines that morning, he would have been much surprised to see so many of his natural enemies intrude on his property at so early an hour. But, happily, he had not yet risen, and we were able to enter upon our investigations without being watched or interrupted by him. Our first move was to go in a body to the southwest chamber, take down the picture, examine it with a magnifying-glass and satisfy ourselves that the words I had picked out of its mazy lines were really to be found there. This done and my veracity established, we next proceeded to the closet where, according to the instructions embodied in this picture, the secret spring was to be found by which some unknown and devilish machinery would be released in the library below. To my great satisfaction the active part in this experiment was delegated to me. Durbin continued to be a mere looker-on. Drawing out the two large drawers from their place at the end of this closet, I set them aside. Then I hunted for and found the small loophole which we had been told afforded a glimpse of the library hearthstone; but seeing nothing through it, I called for a light to be placed in the room below.
