The apartment had no secrets to reveal. It was absolutely bare, and empty of anything except a broken old sconce lying in a corner. The whole room, however, was indescribably dusty and musty, and he was very thankful to push aside a curtain of chain mail and descend the staircase. At its foot he saw lying the coveted papers. Forgetful of everything else, he sat down upon the lowest step, and by the light of his lantern proceeded to examine them. They more than fulfilled his utmost expectations. There was a complete cipher and its key, a full list of the members of the cabinet who were to pass upon the treaty, with comments on each, and a memorandum of the amounts to be given to certain of them, coupled with suggestions as to the attitude which Darcy should take towards others, together with precise instructions as to the carrying out of the plot; the whole signed by Riddle in the interests of the firm. The evidence was complete, and Stanley gasped as he realised the advantage of this tremendous stroke of luck. One fact which his perusal had elicited caused him to draw a long sigh of relief. Miss Fitzgerald's name was not mentioned in the incriminating document, and so much did he wish to believe her innocent, that in spite of all accumulated evidence, he felt a sense of exultation that he could still, if worst came to worst, shield her from the effects of her own folly. He told himself that he might, after all, prove to the satisfaction of his own conscience that she was innocent of criminal intent. Darcy he would have no mercy for. He must be punished for his crime, and the fact of his being the criminal would give Inez her freedom, and then---- Ah! but if Belle Fitzgerald was innocent--was he not in honour bound to _her_? And at that moment he realised that he had mistaken pity for love, that Darcy possessed the woman in the world most worth having, and that he was unworthy of her. His meditations were interrupted by the sound of voices near him. Somebody laid a hand on the other side of the door. They were tampering with it again, and, for more reasons than one, he wanted the fact of his having gained entrance to the tower to remain a secret. Putting the letter in his inside pocket, he softly retraced his steps to the upper chamber.
