But Zeno knew nothing of Arethusa, yesterday his slave, and since last night the woman of his heart, for in the haste and stress of that tremendous half-hour, Gorlias could tell him nothing, except that he was Gorlias and not the Emperor, and that the deed giving Tenedos over to Venice was signed and in his bosom; and Zeno supposed that he had devised all the wonderful scheme, which looked so simple as soon as it began to be carried out. Arethusa, he thought, was safe at home; sleepless, worn out with waiting, trembling with anxiety, perhaps, but safe. Now that the deed was done, now that Andronicus was bound, and Johannes, his father, was restored to the throne, Carlo Zeno thought only of leaving Constantinople without delay, before the Emperor could take back his word, and revoke the cession of Tenedos. For Zeno did not put his trust in Oriental princes, and feared the Greeks even when they offered gifts. With a swift Venetian vessel and a fair wind, the coveted island could be reached in two days, or even less; its governor had always at heart been faithful to Johannes, and would obey the deed which Gorlias had thrust into Zeno's hand in the tower, and if once the standard of St. Mark were raised on the fort there was small chance that any enemy would be able to tear it down. Therefore, just when the soldiers were lifting Johannes from his horse to carry him to the throne-room with wild triumph and rejoicing, Zeno slipped from the saddle to escape notice, elbowed his way to the outskirts of the crowd, and was on the point of making for the gate when Gorlias found him again. 'Arethusa asks you to come to her,' Gorlias said. 'I am going----' 'No. She is here. It was all her plan; she risked her life for it, we were a few moments late, and she has been tortured. Come quickly!' Zeno's face changed. Gorlias saw that, even in the dim light of the now distant torches. It was the change that comes into a master swordman's face when he makes up his mind to kill, after only defending himself because his adversary has tried some dastardly murderous trick of fence. But Zeno said nothing as he strode swiftly by his companion's side. Gorlias had found her and had brought her into the lower chamber of the tower, now deserted by the guards. The captain's wife had been standing at the door, not daring to go out amongst the half-frantic soldiers. She might have fared ill at their hands if she had been recognised just then as the wife of the Emperor's gaoler. So she had stood under the archway, watching and listening, and Gorlias had given Zoë half-fainting into her care while he went to find Zeno.
