Her tone was contrite and regretfully thoughtful, as if the explanation were irrefutable but humiliating. Eve was, on the whole, a good woman, and is believed to be in Paradise; yet with the slight previous training of a few minutes' conversation with the serpent she was an accomplished temptress, and her rustic taste for apples has sent untold millions down into unquenchable fire. It was a mere coincidence that Eve should have been always called Zoë in the early Greek translations of Genesis, and that Zoë Rhangabé should have inherited a dangerous resemblance to the first beautiful—and enterprising—mother of men.

'I would stay if I could,' Zeno said. 'But indeed I have an appointment, and I must go.'

'Is it very important, very—very?'

Zeno smiled at her now, but did not answer at once. Instead, he walked to the window, opened the shutters again, and looked out. The night was very dark. Here and there little lights twinkled in the houses of Pera, and those that were near the water's edge made tiny paths over the black stream. After his eyes had grown used to the gloom Zeno could make out that there was a boat near the marble steps, and a very soft sound of oars moving in the water told him that the boatman was paddling gently to keep his position against the slow current. Zeno shut the window again and turned back to Zoë.

'Yes,' he said, answering her last speech after the interval, 'it is very important. If it were not, I would not go out to-night.'

He was going out of the house, then. She knew that he rarely did so after dark, and she could not help connecting his going with the invitation he had given to Polo and his daughter for the next day. Zoë's imagination instantly spun a thread across the chasms of improbability, and ran along the fairy bridge to the regions of the impossible beyond. He was to be betrothed to Giustina to-morrow, he was going now to settle some urgent matter of business connected with the marriage-contract; or he was betrothed already; yes, and he was to be married in the morning and would bring his bride home; Zoë, in her lonely room upstairs, would hear the noisy feasting of the wedding-guests below——

When the thread broke, leaving her in the unreality, her lip quivered, and she was a little pale. Zeno was standing beside her, holding her hand.

'Good-night, Arethusa,' he said in a tone that frightened her.

The words sounded like 'good-bye,' for that was what they might mean; he knew it, and she guessed it.

'You are going away!' she cried, springing to her feet and slipping her hand from his to catch his wrist.
