“We are off Hammam-Lif, madame,” he said. “We are going to lie to for half-an-hour to take in cargo.”

To the Princess that half-hour seemed all eternity. She remained upon deck, and whenever she heard the splash of oars as a boat drew near, or the guttural sound of an Arab voice, she trembled, and, staring into the blackness, fancied that she saw the tall figure, the pointed head, and the deformed eyes of the jewel doctor. But the minutes passed. The cargo was all got on board. The boats drew off. And once again the ship shuddered as the heart of her began to beat, and the ebon water ran backward from her prow.

Then the Princess was glad. She laid the hand on which shone Safti’s emerald upon the bulwark, and gazed towards the sea, turning her back upon the lights of Hammam-Lif. She thought of safety, of Russia. She did not hear a soft step drawing near upon the deck behind her. She did not see the flash of steel descending to the bulwark on which her hand was laid.

But suddenly the horrible cry of a woman in agony rang through the night. It was instantly succeeded by a splash in the water, as a tall figure dived over the vessel’s side.

When the sun rose on the following day over the minarets of Tunis the Stella d’ltalia, with the Princess on board, was far out at sea.

The emerald of Safti was once more in the little house in the Rue Ben-Ziad.

It was still upon the Princess’s finger.
