'There is the man in the boat. But watching is useless. If any one surprises us in the tower, I can get away; but if I am caught by an enemy from the water the game is up. That is the only danger.'

'That is the only danger,' Zoe repeated, more to herself than for him.

He saw that she had understood now, and that she would not try to keep him longer, nor again beg to be taken. She went with him to the door of the vestibule without calling the maids, and she parted from him there, very quietly.

'G.o.d speed you!' she said, for good-bye.

When he reached the outer entrance and looked back once more, she was already gone within, and the quiet lamplight fell across the folds of the heavy curtain.

CHAPTER X

Zeno left his house noiselessly half an hour later, after changing his clothes. He was now lightly clad in dark hose and a soft deerskin doublet with tight sleeves, a close-fitting woollen skull-cap covered his head, and he had no weapon but one good knife of which the sheath was fastened to the back of his belt, as a sailor carries it when he goes aloft to work on rigging. The night was cool, and he had a wide cloak over his shoulders, ready to drop in an instant if necessary.

It was intensely dark as he came out, and after being in the light he could hardly see the white marble steps of the landing. He almost lost his balance at the last one, and when he stepped quickly towards the boat, to save himself, he could not see it at all, and was considerably relieved to find himself in the stern sheets instead of in the water.

'Gorlias!' he whispered, leaning forwards.

'Yes!' answered the astrologer-fisherman.

The light skiff shot out into the darkness, away from the sh.o.r.e, instead of heading directly for Blachernae. After a few minutes Gorlias rested on his oars. Zeno had grown used to the gloom and could now see him quite distinctly. Both men peered about them and listened for the sound of other oars, but there was nothing; they were alone on the water.

'Is everything ready?' Zeno asked in a low tone.

'Everything. At the signal over eight hundred men will be before Blachernae in a few minutes. There are fifty ladders in the ruined houses by the wall of the city. The money has had an excellent effect on the guard, for most of them were drunk this evening, and are asleep now. In the tower, the captain is asleep too, for his wife showed the red light an hour ago. She took up the package of opium last night by the thread.'

'And Johannes himself? Is he ready?'

'He is timid, but he will risk his life to get out of the tower. You may be sure of that!'

'Have you everything we need? The fishing-line, the tail-block, and the two ropes? And the basket? Is everything ready in the bows, there?'

'Everything, just as you ordered it, and the rope clear to pay out.'

'Give way, then.'

'In the name of G.o.d,' said Gorlias, as he dipped his oars again.

'Amen,' answered Zeno quietly.

The oars were m.u.f.fled with rags at the thole-pins, and Gorlias was an accomplished oarsman. He dipped the blades into the stream so gently that there was hardly a ripple, and he pulled them through with long, steady strokes, keeping the boat on its course by the scattered lights of the city.

Zeno watched the lights, too, leaning back in the stern, and turning over the last details of his plan. Everything depended on getting the imprisoned man out of the Amena tower at once, and he believed he could do that without much difficulty. At first sight it might seem madness to attempt a revolution with only eight hundred men to bear arms in the cause, against ten or fifteen thousand, but the Venetian knew what sort of men they were, and how profoundly Andronicus was hated by all the army except his body-guard. The latter would fight, no doubt, and perhaps die to a man, for they had everything to lose, and expected no quarter; but for the next two hours most of them would be still helplessly asleep after their potations, and if they woke at all they would hardly be in a condition to defend themselves. Money had been distributed to them without knowledge of their officers, purporting to be sent to them from Sultan Amurad, now in Asia Minor.

It had pleased the Turk more than once to keep the guards in a good humour towards him, and the soldiers were not surprised. Besides, they cared very little whence money came, provided it got into their hands, and could be spent in drink, for they were not sober Greeks or Italians; most of them were wild barbarians, who would rather drink than eat, and rather fight than drink, as the saying goes.

For nearly twenty minutes Gorlias pulled steadily upstream. Then he slackened speed, and brought the boat slowly to the foot of the tower.

The windows were all dark now, and the great ma.s.s towered up into the night till the top was lost in the black sky. During the hours Gorlias had spent in fishing from the pier he had succeeded in wedging a stout oak peg between the stones; he found it at once in the dark, got out and made the boat fast to it by the painter. His bare feet clung to the sloping surface like a fly's to a smooth wall; he pulled the boat alongside the pier, holding it by the gunwale, and held up his other hand to help Zeno. But the Venetian was in no need of that, and was standing beside his companion in an instant. It was only then, a whole second after the fact, that he knew he had stepped upon something oddly soft and at the same time elastic and resisting, that lay amidships in the bottom of the boat, covered with canvas. The quick recollection was that of having unconsciously placed one foot on a human body when getting out. He had taken off his shoes, but the cloth soles of his hose were thick, and he could not feel sure of what he had touched. Besides, he had no time to lose in speculating as to what Gorlias might have in the skiff besides his lines and his coil of rope.

Gorlias now got the end of the fishing-line ash.o.r.e, and took it in his teeth in order to climb up the inclined plane of the pier on his hands and feet, ape-fashion. In a few seconds he had found the end of a string that hung down from the blackness above, with a small stone tied to it to keep it from being blown adrift. To this string he bent the fishing-line. Until this was done neither of the men had made the least sound that could possibly be heard above, but now Gorlias gave a signal. It was the cry of the beautiful little owl that haunts ruined houses in Italy and the East, one soft and musical note, repeated at short and regular intervals. The bird always gives it thus, but for the signal Gorlias whistled it twice each time, instead of once. No living owl ever did that, and yet it was a thousand to one that n.o.body would notice the difference, if any one heard him at all, except the person for whom the call was meant.

He had not been whistling more than a quarter of a minute when he felt the twine pa.s.sing upwards through his fingers, and then the line after it. He let the latter run through his hand to be sure that it did not foul and kink, though he had purposely chosen one that had been long in use, and he had kept it in a dry place for a week.

Zeno had dropped his cloak in the stern of the boat before getting out, and he now sat at the water's edge with his hands on the moving line ready to check the end when it came, in case it were not already fast to the rope that was to follow it. But Gorlias had done that beforehand, lest any time should be lost, and presently Zeno felt the line growing taut as it began to pull on the rope itself.

This had single overhand knots in it, about two feet apart, for climbing, and instead of coiling it down, Gorlias had ranged it fore and aft on the forward thwarts so that it came ash.o.r.e clear. Whatever the astrologer's original profession had been, it was evident that he understood how to handle rope as well as if he had been to sea.

Moreover Zeno, who was as much a sailor as a soldier, understood from the speed at which the rope was now taken up, that there was a tolerably strong person at the other end of it, high up in the topmost story of the tower. The end came sooner than he expected, and a slight noise of something catching and knocking against the inner side of the boat brought Gorlias instantly to the water's edge.

'The tail-block is fast to the end,' he whispered; 'and the other line is already rove, with the basket at one end of it. When you are aloft, you must haul up the climbing rope and make the block fast--you understand.'

'Of course,' Zeno answered, 'I have been to sea.'

'Whistle when you are ready and I will answer. As he comes down I can check the rope with a turn round a smooth stone I have found at the corner of the tower. You must come down the climbing rope at the same time, and steer the basket as well as you can with your foot.'

'Yes. Is all fast above?'

Gorlias listened.

'Not yet,' he whispered. 'Wait for the signal.'

It came presently, the cry of the owlet repeated, as Gorlias had repeated it. Zeno heard it and began to climb, while Gorlias steadied the rope, though there was hardly any need for that. The young Venetian walked up with his feet to the wall, taking the rope hand over hand, as if he were going up a bare pole by a gant-line.

When he was twenty feet above the pier and was fast disappearing in the darkness, something moved in the boat, and a white face looked up cautiously over the gunwale. It was a woman's face. Zeno had stepped upon her with his whole weight when he was getting ash.o.r.e, but she had made no sound. Her eyes tried to pierce the gloom, to follow him upwards in his dizzy ascent. Soon she could not see him any longer, nor hear the soft sound of his cloth-shod feet as he planted them against the stones.

Up he went, higher and higher. Gorlias steadied the end below, keeping one foot on the block lest it should thrash about on the stones and make a noise. He could feel each of Zeno's movements along the rope; and though he had seen many feats in his life, he wondered at the wind and endurance of a man who could make such an ascent without once crooking his leg round the rope to rest and take breath. But Carlo Zeno never stopped till his feet were on the slight projecting moulding of the highest story, and his hands on the stone sill.

As he drew himself up with a spring his face almost struck the chest of a large woman who was standing at the window to receive him. He saw her outline faintly, for there was a little light from one small lamp, placed on the floor in the farthest corner of the oblong room. The tower was square, but the north side of the chamber was walled off to make a s.p.a.ce for the head of the staircase and a narrow entry. The single door was in this part.i.tion. Zeno looked round while he took breath, and he was aware of a tall man with a long beard who stood on one side of the window, and seemed inclined to flatten himself against the wall, as if he feared being seen from without, even at that height and in the dark.

The woman moved a step backwards, and Carlo put one leg over the window-sill and got in. He took his skull-cap from his head and bowed low to the imprisoned Emperor before he spoke to the woman in a whisper.

'I will haul up the basket,' he said, and he laid his hands on the knotted rope to do so.

But the tall man with the beard touched him on the shoulder, and spoke in a low voice.

'We must talk together,' he said.

Zeno hardly turned his head, and did not stop hauling in the rope.

Below, Gorlias was steering the tail-block clear of the wall, lest it should strike the stones and make a noise.

'This is no time for talking,' Zeno said. 'When your Majesty is free and in safety we can talk at leisure.'

The knotted rope was coming in fast; Zeno threw it upon the floor behind him in a wide coil to keep it clear.

'Stop!' commanded the Emperor, laying one hand on the Venetian's arm.

Zeno set his foot on the rope to keep it from running out, and turned to the prisoner in surprise.
