As yet, neither Vito nor any member of the household, except Zoë, knew that Zeno was a prisoner, held for ransom. It had pleased him to go out of his house during the previous night, and some important business detained him; that was all. When he was at leisure he would come home. The men-servants who had waited on the guests and had heard Tocktamish's words, to the effect that Zeno had sent him for money, looked upon the statement as a clumsy trick which the half-drunken robber was trying to play in Zeno's absence, and as nothing more. But they had been far too badly frightened to stay and listen, as has been seen. To Vito, who was, nevertheless, by far the best of them, it had been a matter of utter indifference whether the Tartar cut the throats of the four guests or not, compared with the urgent necessity of keeping out of his reach. If the master had been present another side of their character would have come into play, but as he was absent they had thought of their own safety first.

CHAPTER XVIII

The sun had set, and the wide court of Blachernæ was filled with purple light to the wall tops, like a wine-vat full to the brim; and everything that was in the glow took colour from it, as silver does in claret, the polished trappings of the guards' uniforms, the creamy marble steps of the palace, the white Tunisian charger of the officer who rode in just then, and the swallows that circled round and round the courtyard. The world moved in that short deep dream that comes just when the sun has slipped away to rest, when the light is everywhere at once, so that things cast no shadows on the ground, because they glow from within, as in fairyland, or perhaps in heaven.

The officer rode in on his charger, and after him entered a girl slave, dressed in coarse blue cotton, and carrying on her head a small round basket, which was covered with a clean white cloth. The four corners of the napkin hung down, and one of them would have flapped across her face if she had not held it between her teeth to keep it down. It partly hid her features, and her head was tied up in a blue cotton kerchief passed twice round and knotted upon her forehead. She limped a little as she walked. What could be seen of her face was pale and quiet, and had a rather fixed look.

She was walking boldly through the gate, without slackening her pace, when one of the two sentinels stopped her, and asked where she was going. She stood still, and one hand steadied the basket on her head, while the other pointed to the Amena tower.

'My mistress sends some fine wheat bread and cream cheese to the wife of the captain who keeps the tower,' said Zoë, affecting the mincing accent very common with female slaves and Greek ladies' maids.

The second sentinel, returning on his short beat, now came up and stood on her other side. He was a big Bulgarian, and he lifted one corner of the cloth and looked down into the basket, merely for the sake of detaining the girl. He saw the wheaten loaves and the cream cheese neatly disposed on a second napkin, and the cheese was nested in green leaves to keep it fresh. Both the soldiers at once thought of tasting it with the points of their daggers, but at that moment the officer of the watch strolled out of the guard-house, a magnificent young man in scarlet and gold. The two sentinels at once turned their backs on the cheese and Zoë, and marched away in opposite directions on their beats, leaving her standing in the middle. The officer was far too high and mighty a person to look at a slave-girl or her basket, and Zoë therefore went on without turning her head, taking it for granted that she was now free to enter. In her baggy blue cotton clothes, and with her face almost covered by the napkin, there was nothing about her to attract attention, unless it were her slightly limping gait; and she instinctively made an effort to walk evenly, for she could not help feeling ashamed of being suddenly lame, as perfectly sound and healthy people do. But she realised that the folded letter was in the wrong shoe and increased her lameness, whereas if she had carried it in the other it might have made walking easier.

She went from under the great gate into the liquid purple light in the court, and it was pleasant to be in it. But then again it made her think of yesterday, when she had sat in her window at sunset, not dreaming of all that was to happen to her in one night and one day. It made her think of the man she loved so dearly, imprisoned somewhere under the great city, starving and thirsting no doubt, and face to face with thoughts of death; and it was to save him that she was crossing the courtyard of Blachernæ disguised as a household slave. It was because there was no other way; and if Gorlias Pietrogliant failed her, or came too late, the end would overtake her in a few hours, or perhaps quite suddenly, which would be more merciful. She knew what she was doing, and she did not deceive herself. They would put out her eyes first; but that would be the least of the cruel things they would do to her, if Gorlias failed.

She was only a weak girl, after all, and once or twice, when she thought of the pain, a sharp little shiver ran down her back to her very heels, and things swam before her for an instant in the deep sea of colour; but that only lasted for a moment, and when she reached the foot of the tower and went in under the archway that led to the door, she was thinking of Zeno again, and of nothing else.

It was as Gorlias had told her. A very different watch was set there since the attempt of the previous night, and she found herself face to face with an obstacle she had not anticipated. The iron door was shut and was guarded by two huge Africans in black mail armour, who stood on either side with drawn scimitars.
