He stepped to the ground again and reached the door in time to enter with the last of the train that followed Zoë. In the dining-hall things had been left as they were when Tocktamish and Omobono went out. The table was in confusion, and flooded with wine that had run down to the floor, and two or three chairs were upset. Gorlias filled a silver pitcher with Chian; but when he turned towards the window Zoë was the only one who saw him empty into the wine the contents of a small vial which he seemed to have had ready in the palm of his hand. He called Carlo's man. 'Take it to him,' he said. 'You can easily pass it through the bars.' 'It is not much wine,' observed the man doubtfully. 'He will drink that at a draught.' 'If he asks for more, fill the pitcher again,' answered Gorlias. 'If he falls asleep, let me know.' The man went off. 'Clear away all that,' said Zoë to the men-servants who stood looking on. 'The master must not find this confusion when he comes home.' Her tone and her manner imposed obedience, and besides, they knew that Tocktamish was safe for a while. They began to clear the table at once, and Zoë left the room followed by Gorlias and her two maids, who had been silent witnesses of what had passed. Upstairs, they left her alone with the astrologer, and disappeared to discuss in whispers the wonderful things that were happening in the house. 'Where is he?' asked Zoë, as soon as the maids were gone. 'He is in a dry cistern near the north wall of the city.' 'Hiding?' 'No--a prisoner. In escaping last night he ran among the soldiers who were to have helped us, and they held him for a ransom. The Tartar came to extort the money. You know all.' 'At least, he is safe for the present,' Zoë said, but very doubtfully, for she did not half believe what she said. 'No,' Gorlias answered; 'he is not safe for long, and we must get him out. They demand a ransom, but they know well enough that even if they get it they will not dare to let him go free, since he could hang them all by a word.' 'What will they do?' 'If they can get the money they will let him starve to death in the cistern. If they do not, they will give him up to Andronicus for the reward. The Emperor has proclaimed that he will give ten pounds of gold to any one who will bring him Carlo Zeno, dead or alive. That is not enough.' 'The Emperor knows it was he?' asked Zoë with increasing anxiety. 'Yes.' 'How?' 'I do not know. Some one has betrayed us.' 'Us all?' 'I fear so.' 'But you yourself? Do you dare go about?' 'I have many disguises, and they who know the fisherman do not know the astrologer.' 'But if you should be taken?' 'A man cannot change his destiny. But look here. I have something from Johannes already. He has changed his mind; he regrets not having let us take him out last night, and he sends me this by the captain's wife.' Gorlias produced a parchment document. 'What is it?' 'The gift of Tenedos to Venice.'
