Again Benilo's lips straightened in a hard, drawn line. Stooping over the alchemist, he whispered two words into his ear, which caused Dom Sabbat to glance up with such an expression of horror that Benilo involuntarily burst into a loud laugh, which sent the other spinning to his task.

Ransacking some remote corner in his devil's kitchen he at last produced a tiny phial, which he wrapped in a thin scroll. This he placed with trembling hands into those eagerly stretched out to grasp it and received therefor a hand full of gold coin, the weight of which seemed to indicate that secrecy was to constitute no small portion of the bargain.

After having conducted his visitor to the entrance, where he took leave of him with many bends of the head and manifold protestations of devotion, Dom Sabbat locked his abode and Benilo hastened towards the city.

As he mentally surveyed the events of the evening even to their remotest consequences, he seemed to have neglected no precaution, nor omitted anything which might eventually prevent him from triumphing over his opponents. But even while reviewing with a degree of satisfaction the business of the night, terrible misgivings, like dream shadows, drooped over his mind. After all it was a foolhardy challenge he had thrown to fate. Maddened by the taunts of a woman, he had arrayed forces against himself which he must annihilate, else they would tear him to pieces. The time for temporizing had passed. He stood on the crater of a volcano, and his ears, trained to the sounds of danger, could hear the fateful rumbling in the depths below.

In that fateful hour there ripened in the brain of Benilo the Chamberlain a thought, destined in its final consequences to subvert a dynasty. After all there was no security for him in Rome, while the Germans held sway in the Patrimony of St. Peter. But—indolent and voluptuous as he was—caring for nothing save the enjoyment of the moment, how was he to wield the thunderbolt for their destruction, how was he to accomplish that, in which Crescentius had failed, backed by forces equal to those of the foreigners and entrenched in his impregnable stronghold?

As Benilo weighed the past against the future, the scales of his crimes sank so deeply to earth that, had Mercy thrown her weight in the balance it would not have changed the ultimate decree of Retribution. Only the utter annihilation of the foreign invaders could save him. Eckhardt's life might be at the mercy of John of the Catacombs. The poison phial might accomplish what the bravo's dagger failed to do,—but one thing stood out clearly and boldly in his mind; the German leader must not live! Theodora dared not win the wager,—but even therein lay the greater peril. The moment she scented an obstacle in her path, she would move all the powers of darkness to remove it and it required little perspicuity to point out the source, whence it proceeded.

At the thought of the humiliation he had received at her hands, Benilo gnashed his teeth in impotent rage. His pride, his vanity, his self-love, had been cruelly stabbed. He might retaliate by rousing her fear. But if she had passed beyond the point of caring?

As, wrapt in dark ruminations, Benilo followed the lonely path, which carried him toward the city, there came to him a thought, swift and sudden, which roused the evil nature within him to its highest tension.

Could his own revenge be more complete than by using his enemies, one for the destruction of the other? And as for the means,—Theodora herself would furnish them. Meanwhile—how would Johannes Crescentius bear the propinquity of his hereditary foe, the emperor? Might not the Senator be goaded towards the fateful brink of rebellion? Then,—Romans and Germans once more engaged in a death grapple,—his own time would come, must come, the time of victory and ultimate triumph.
