Omobono only guessed it from a certain increase of his natural reserve, but that was enough for the experienced secretary, who was wonderfully careful not to speak unless Zeno spoke to him, and, above all, not to mention the existence of the women's apartment upstairs. On the other hand, although it was a Sunday, he had expected to be sent by his master to draw the money from the house of Cornèr, according to Pesaro's letter, of which he had thoroughly mastered the contents. But the order was not given, and as Zeno was neither forgetful of details nor slack in matters of business, Omobono began to wonder what had happened.

On Monday Zeno's mood had not changed, nor did he send for the money, and the secretary's curiosity grew mightily; on Tuesday it became almost unbearable. So far as he knew, and he knew most things that went on in the house, Zeno had only once gone upstairs, when he had supped with Zoë on Saturday evening, and had remained barely an hour. Since then he had not even asked after the slave, and no one had seen her except the two little maids, who came out upon the landing to receive the meals at regular hours, but never spoke to the men-servants. The secretary could have asked to see Zoë, to enquire if she needed anything, and she would certainly have received him; but he was afraid to do so without orders, and Zeno gave none, and might come in at the very moment when Omobono was there. The industrious secretary had fits of abstraction over his letters and accounts, and stared out of the window, stroking his neatly-trimmed grey beard very thoughtfully.

On Wednesday, a little before noon, Zoë was sitting in her window, and she again saw Zeno go down the steps to the water and get into his skiff. It was always there now, even at dawn, for since there had been women in the house Zeno had been rowed to another place for his morning plunge in the Golden Horn. To-day he was dressed with particular care, Zoë thought, as she caught sight of him, and she did not draw back from the window, as she had done the first time, but stayed where she was, and she wished in her heart that he would look up and see her. He did not even turn as he stepped into the boat, and she thought he held his head lower than when she had last seen him, and looked down, and raised his shoulders a little like a person determined not to look to the right or the left. Then the two men pulled the skiff away upstream, and she watched it till she could no longer distinguish it from many others that moved about on the water in the direction of the palace. She wondered where he went.

He had not been gone ten minutes when a man came to the gate of the fore-court on the other side of the house, and asked to see the secretary. He was simply dressed in a clean brown woollen tunic, that hung almost to the ground. It had wide sleeves, and they hid his joined hands as he stood waiting, in the attitude monks often take before a superior, or when reciting prayers before meals. But the man was not a monk, for he wore a broad belt of dark red leather, in which he carried a sheathed knife, a Syrian ink-horn, and a small cylindrical case of hammered brass, which held his reed pens. On his head he wore a tall felt cap, such as dervishes now wear.

The slave at the door looked at him attentively before admitting him. There was something unusual in his expression, though his features were not very marked, and he had the rather pasty complexion that is so common in the East. His eyes were perhaps a little longer and more almond-shaped than those of the average Greek or Bokharian, and he kept them half-closed. His scanty black beard had a few grey hairs in it. His nostrils curved sharply, but the nose was neither very large nor markedly aquiline. A commonplace face enough in Constantinople; but there was something oddly fixed in its expression, that made the slave feel uncomfortable and yet submissive. Many persons of all conditions came to the merchant's house on business during the day, and it was the rule to send them to Omobono. The slave's business was to keep out thieves, beggars, and suspicious characters; he stood aside, admitted the visitor to the court which separated the house from the street, and shut the gate again.

One of the free house-servants, of whom two or three were always waiting, came forward—a square-shouldered Venetian named Vito, who had been a sailor and had followed Zeno for years. He enquired the stranger's name and business.

'I am Gorlias Pietrogliant,' was the answer. 'My business with the secretary is private.'

The serving-man disappeared, and returned a moment later to conduct the visitor to the private room of the counting-house on the ground floor, where Omobono sat behind a high desk covered with papers and slips of parchment.

Omobono straightened himself on his stool and eyed the newcomer with a look of enquiry, at the same time drawing from his right arm the half sleeve of grey cotton which he always put on when he was going to write long, lest a spot of ink should stain the soft linen wrist-band which just showed below the tight cuff of his coat. He was a careful man. He looked at his visitor keenly, till he suddenly became aware that his scrutiny was returned with a rather disquieting fixedness.

'I am Gorlias Pietrogliant,' said the stranger.
