He paused, and looked fearfully around; then wiped the sweat off his white face with a nervous gesture. Tait eyed him in amazement, and could not understand what had come over his usually self-possessed friend; but he had no time to speak, for Claude, with an irrepressible shiver, whispered in a low voice: "What if my mother should be guilty, after all? Ah, you may well look astonished, but that is the hideous doubt which has haunted me for days. My mother says she ran at my father with a dagger, but fainted before she struck him. What if she did not faint; if she really killed him, and Hilliston, knowing this, is trying to screen her, and trying to save me from knowing the truth?" "But, my dear fellow, the trial----" "Never mind the trial. We now know that Denis swore falsely when he asserted that my father was not in the house on that night. We know that he was in the house, and that my mother found him with Mona Bantry. Her jealousy might have carried her to greater lengths than she intended to go. Denis saved her at the trial by telling a lie; but we know the truth, and I cannot rid myself of a doubt, that she may be guilty. If so, in place of being an enemy, Hilliston is acting the part of a friend in placing obstacles in our way." Tait shook his head. "I do not believe Mrs. Bezel is guilty," he said quietly; "if she had been, she would certainly not have written to you, and thus forced Hilliston to show you the papers. Banish the thought from your heart, Claude. I am as certain as I sit here that your mother is innocent of the crime." "If I could only be certain!" "And why should you not be," exclaimed Tait vigorously. "An eye-witness could tell you the truth." "Where can I find an eye-witness?" cried Claude, with an impatient frown. "Mona Bantry and Jeringham have both fled; they are probably dead by this time. My mother denies that she struck the blow, and Hilliston, she says, was at the ball when the murder took place. Who can tell me the truth?" "Denis Bantry," said Tait quietly. "Listen to me, Claude. The episode of the garnet scarfpin, which to my mind is the clew to the assassin, is only known to your mother, to Hilliston, and to Denis Bantry. Now Hilliston denies that such a trinket exists; your mother insists that it was found on the bank of the river after the murder. The only person who can give the casting vote--who can arbitrate, so to speak--is Denis Bantry." "And where is Denis Bantry? Lost or dead, years ago." "Nothing of the sort, my friend. Denis Bantry is alive and in this neighborhood. Yes; Jenny Paynton admitted to me that the scarfpin episode was related to her by their old servant, Kerry. Therefore, it naturally follows that Kerry is Denis Bantry." "But why is he hiding here under another name?" said Larcher, after he had digested this piece of information, with a due display of astonishment.
