The slave-girl, withdrawn into the shadow, and engaged in spinning wool, looked up furtively again and again at the face of the Empress, who was too much absorbed in her own thoughts to notice her. The girl saw passion after passion chase each other like dark clouds across Agrippina’s face. At one moment the clenched hand, the quivering nostril, the flashing glance, showed that the thought of possible vengeance was passing through her soul. Then for a moment a softer expression would smooth her features, as she dreamed of the possibility of her son’s remorse. Then terror would express itself on her features as she recognised the frightfulness of her position. Last of all, an infinite languor seemed to droop through her whole being, as she resigned herself to sullen despair.

In those dark uncertain hours she realised all the error and infatuation of her life. Impunity, after so many crimes? Impunity, when the menacing spectres of perjury and adultery and murder kept starting upon her out of the darkness? Crispus Passienus poisoned; Lucius Silanus hounded to death by lying informers; his murdered brother Junius; her husband Claudius—were they all to be unavenged? Had the gods no thunderbolts? Had the guilty ever escaped them? Had Tiberius died in peace after his atrocities and crimes? Had Gaius died in peace amid the tears of his beloved? Had Messalina escaped the consequences of her debaucheries and murders? Did not the violated laws of heaven put into the hand of their transgressors their whips of flame? And as she began to realise that Retribution dogs guilt like its own inevitable shadow, the line of the old Greek poet rang ominously in her memory:—

‘Though the mills of God grind slowly, yet they grind exceeding small.

Though in patience long He waiteth, with exactness grinds He all.’

And, all the while, the nightingales in the gardens of her villa were pealing forth their ecstasy, and the stars shone, and the soft wind breathed of perfume.

CHAPTER XXXVI
SELF-AVENGED

‘Sua quemque fraus, suum facinus, suum scelus, sua audacia, de sanitate ac mente deturbat. Hæ sunt impiorum furiæ, hæ flammæ, hæ faces.’—Cic. In Pisonem, xx. 46.

Nero, in a mood of fearful restlessness, awaited news of the issue of his design. Long ere this he ought to have received the intelligence which would relieve his life of a great burden. Hardly for a moment did the enormity of the crime he was committing press upon a soul given up to shameful self-indulgence. He only yearned to be rid of a figure which frightened him, and checked the rushing chariot-wheels of his passions. Once free from his mother and her threats, he would marry Poppæa and give himself up to whatever his heart desired. Too uneasy to sleep, too much occupied with anxiety to follow his usual pleasures, he talked to Tigellinus, who alone was with him, pacing up and down the hall of his villa, tossing down goblet after goblet of wine, and trying to conjure before his imagination the scene which was being enacted. Surely it could not fail! And, if it succeeded, the dead tell no tales, and the sea-waves would keep the secret! Every one had seen the warmth of his attention to his mother, and the affectionate tenderness with which he had bidden her farewell. What remained but publicly to deplore with tears the sad bereavement which had been inflicted on his youth by the treachery of winds and waves, and then to decree to his mother’s memory the temples and the altars which would be ostentatious proofs of his filial regard?

But how was it that no news had reached him? Three or four hours had passed. By this time the deed must have been done. Something had happened—so much was certain; for though he dared not send out to inquire, as though he suspected that anything was wrong, yet from the balcony he saw the torches moving in hurried streams hither and thither, and he could hear the distant cries of excitement and alarm.

A messenger was announced.
