"Then probably the two words you saw were Greek. Now, the first thing to be found is the knife; the second, and far more important fact, is the meaning of those words. Are you sure not to forget them? Can you, perhaps, write them down?"

"I'll never forget them as long as I live; they are engraven in my mind."

"Then go and look for the knife. Come back to me to-morrow; perhaps I may be of further help to you, that is, if you need more help."

Uros thanked the old woman, and then asked her where she had learnt all the wonderful things she knew.

"From my own mother. Once a trade was in one family for ages; every generation transmitted its secrets with its implements to the other. It is true, people only knew one thing; but they knew it thoroughly. Nowadays, young people are expected to have a smattering of everything; but the sum of all their knowledge often amounts to nothing."

Uros, taking leave of the wise old woman, went down the road leading from Porta Pilla to the sea. Soon he came to the spot where Milenko had been found clasping the murdered man in his arms. Then he looked at every tree, at every stone he passed on his way. After a while, he got to the corner where he had seen—in the mirror—the two men disappear. From there he crawled on, rather than walked, so that not a pebble of the road escaped his notice. After about a quarter of an hour, he came to a shrub of a dusty, greyish green—it was an Agnus castus in full bloom. He recognised it at once; it was the bush that had looked so silvery by the light of the moon within the magic mirror. His heart began to beat violently. As he looked round, he fancied he would see the murderer start from behind some tree and pounce upon him. He looked at the shrub carefully; some of its lower branches and the tops of many twigs were broken. He pushed the leaves aside, and searched within it. The knife was there. He did not see it at first; for its haft was almost the same colour as the roots of the tree, and the point of the knife was sticking in the earth. He took it up and examined it. All the part of the blade that had not been plunged in the earth was stained with blood. It was a common knife, one of those that all sailors wear in their belts. He put it in the breast pocket of his coat, and walked down with long strides. He was but a few steps from the shore.

Reason prompted him now to go to the police and give them the knife; for it might lead to the discovery of the culprit. Still, this was only a second thought—and Uros seldom yielded to practical after-thoughts; and whenever he did so, he always regretted it.

He had not a great idea of the police. They were only good to write things down on paper, making what they called protocols, which complicated everything.

No; it was far better to act for himself, and only apply for help to the police when he could have the murderer arrested.

As he got down to the shore the sun was sinking below the horizon; the silvery waters of the main were now being transmuted into vaporous gold. As he was looking at the sea and sky, from a meteorological, sailor-like point of view, and wondering whereabouts the Spera in Dio was just then, his eyes fell upon a little skiff, which had arrived a few days after they had. It was a Turkish caique, painted in bright prasine green. He had seen it for days when his own ship was loading and unloading, but then it had had nothing particular to attract his attention; he had seen hundreds of these barques in the East. Now, however, he could not help being struck by its vivid green colour. He looked up; the red flag with the half-moon met his eyes. He had but time to see it, when it disappeared, for the sun had set.
