There was no time to be lost either. He did not know the number of his assailants, and though he gave his signal when he reached the window, on the mere chance of being heard, he would not have trusted the answer to it if it had come. Any one could imitate such a sound after hearing it once. If he let down the remaining length of the rope by the fishing-line, and if his enemies were on the pier instead of Gorlias, they would have wit enough to knot the rope where it had been cut, and to send it up again, for him to come down by, and he would drop into their very midst.
He understood all this in an instant, and without hesitation he cast off everything above, and dropped the rope and the fishing-line out of the window. He knew Gorlias well enough to be sure that he would come back before daylight and land if there were no one on the pier, and remove all traces of the attempt.
'My hour has come,' said the Emperor Johannes in solemn terror.
Thereupon he began to say his prayers, and paid no more attention to the others. Zeno took the woman by the wrist.
'We are not lost unless your husband is awake,' he said. 'Take me to him.'
'There is no other way. If he is awake, you will tell him that I got into the tower, and that you have betrayed me into his hands. You will be safe at least, and I will take my chance. If he is asleep I have nothing to fear.'
He drew her to the door and began to unbar it himself. She had understood that he was right, so far as her own safety was concerned, and she helped him. A horn lantern stood on the stone floor in the entry at the head of the stair, where she had left it when she had last come up. Before going down she barred the door outside as usual, and then led the way.
At the first landing she opened a door as softly as she could and went in, leaving Zeno on the threshold. It was the sleeping room, and Zeno heard the captain's stertorous breathing with relief. He went in and looked at the sleeping man's face, which was congested to a dark red by the powerful drug, and Zeno thought it doubtful whether he would ever wake again. The woman, ignorant of the effects of much opium, was afraid her husband might open his eyes, and she plucked at Zeno's sleeve, anxious to get him away; but the Venetian smiled.
