All these precautions Cornelia knew, for Agias was a master at smuggling letters in and out. She had told Drusus frankly all that had passed, and how that she was acting as she did only for his sake. She asked him to trust her, and he wrote back that no doubt of her fidelity to him had crossed his mind; he was not worthy of such love as she had for him; it did not matter very much if Ahenobarbus did kill him, except that it would give her new grief and pain, and the thought of that he could not bear. Cornelia had replied that if Drusus was murdered, she was woman enough and Roman enough to stab Lucius Ahenobarbus on their marriage night, and then plunge the dagger into her own breast. And there the fearful matter had rested; Cornelia smiled by day, and dazzled all she met by her vivacity, and her aggressive queenliness; and by night cried with tearless sobs, which came out of the depths of her heart. And all the time she waited for Agias to foil the plot, and assure Drusus of his life. Let Quintus once be safe, and then--how could she resist the irresistible pressure that would be brought to bear to force her into a hated marriage, which Ahenobarbus--balked though he might be of a fortune--would no longer care to defer? And when Cornelia thought of this, and when she was alone, she would open a little casket, of which no other had the key, and touch the ivory-carved hilt of a small damascened knife. The blade was very sharp; and there was a sticky gum all along the edge,--deadly poison; only a very slight scratch put one beyond aid of physician.
