"My master has no long leisure," he said, "but he begs you to come in."

They left the lodge together, and the porter watched them as they went down the dark corridor, muttering unholy things about the visitor who had disturbed him, and bestowing a few curses on Zorzi. Then he went back to peeling his onions.

As Aristarchi went through the garden, he saw Marietta sitting under the plane-tree, making a little net of coloured beads. Her face was turned from him and bent down, but when he had passed she glanced furtively after him, wondering at his size. But her eyes followed Zorzi, till the two reached the door and went in. A moment later Zorzi came out again, leaving his master and the Greek together. Marietta looked down at once, lest her eyes should betray her gladness, for she knew that Zorzi would not go back and could not leave the glass-house, so that site should necessarily be alone with him while the interview in the laboratory lasted.

He came a little way down the path, then stopped, took a short knife from his wallet and began to trim away a few withered sprigs from a rose-bush. She waited a moment, but he showed no signs of coming nearer, so she spoke to him.

"Will you come here?" she asked softly, looking towards him with half-closed eyes.

He slipped the knife back into his pouch and walked quickly to her side. She looked down again, threading the coloured beads that half filled a small basket in her lap.

"May I ask you a question?" Her voice had a little persuasive hesitation in it, as if she wished him to understand that the answer would be a favour of which she was anything but certain.

"Anything you will," said Zorzi.

"Provided I do not ask about my father's secret!" A little laughter trembled in the words. "You were so severe yesterday, you know. I am almost afraid ever to ask you anything again."

"I will answer as well as I can."
