"I like that what you said," Attilio was heard at last. "Their stars may be lonely. Look how still they are. But men are more like ships that come suddenly upon each other without a warning. And yet they, too, are guided by the stars. I can't get over the wonder of our meeting to-night."

"If you hadn't been so long in saying good-bye we wouldn't have met," said Cosmo, looking at the two men dozing on the thwarts, the whisperers of the tower. They were not at all like what he had imagined them to be.

Attilio gazed at his Englishman for a time closely. He seemed to see a smile on Cosmo's lips. Wonder at his omniscience prevented him from making a reply. He preferred not to ask, and yet he was incapable of forming a guess, for there are certain kinds of obviousness that escape speculation.

"You may be right," he said. "It's the first time in my life that I found it hard to say good-bye. I begin to believe," he went on murmuring, "that there are people it would be better for one not to know. There are women . . ."

"Yes," said Cosmo, very low and as if unconscious of what he was saying. "I have seen your faces very close together."

The other made a slight movement away from Cosmo and then bent towards him. "You have seen," he said slowly and stopped short. He was thinking of something that had happened only two hours before. "Oh well," he said with composure, "you know everything, you see everything that happens. Do you know what will happen to us two?"

"It's very likely that when we part we will never see each other again," Cosmo said, resting his elbows on his knees and taking his head between his hands. He did not look like a man preparing to go ashore.

There were no material difficulties absolutely to prevent him from landing. The foot of the tower with the narrow strip of ground which a boat could approach was not sixty yards off, and all this was in the shadow of its own reflection, the high side of the breakwater, the bulk of the tower, making the glassy water dark in that corner of the shore. And besides, the water in which the boat floated was so shallow that Cosmo could have got to land by wading from where the boat lay without wetting himself much above the knees, should Attilio refuse to come out from under the shelter of the rock. But probably Attilio would not have objected. The difficulty was not there.

Attilio must have been thinking on the same subject, as became evident when he asked Cosmo whether those sbirri knew where he lived. After some reflection Cosmo said that he was quite certain they knew nothing about it. The sbirri had put no questions to him. They had not, he said, displayed any particular curiosity about what he was. "But why do you ask?"

"Don't you know?" said Attilio, with only half-affected surprise. "There might have been a dozen of them waiting for you in the neighbourhood on the chance of your returning, and you have no other place to go to."
