[CHAPTER X.]

WHAT DID SHE KNOW?

Nothing was said for a full minute. Serena stood there, gazing from one to the other as a child might do who finds herself in the presence of two harsh taskmasters. There was something pitiable about her hopelessness; the fighting glint had left her eyes; she stood there downcast and shaking as a slave might do.

"I am afraid I do not understand what you mean," the woman said.

In a way Jack was feeling very sorry for Serena. Ever since he had known Anstruther and been a friend of the household the woman had held a certain subtle fascination for him. Though Jack had not made as yet much progress in the paths of literature, he had all the quick dramatic feeling which is essential to the making of a successful novelist.

It had often occurred to him that so mysterious a figure as Serena would have made a splendid character for a strong novel. He watched the woman carefully now; he saw how her breast was heaving, and what a great fight she was making to keep her emotions under control.

"I am afraid I must press you for an answer," Jack said. "Signor Padini can be nothing to you, and yet you start and cry out when his name is mentioned as if I had struck you a blow. Now, tell me, was the man I speak of a visitor to this house last night? What time did he come?"

"My master's business is my master's business," Serena said sullenly. "He tells me nothing--he tells nobody anything. And who am I, a humble servant like me, to ask questions of my master?"

Rigby shrugged his shoulders hopelessly. He began to see that there was nothing to gain here. He nodded to Jack and half turned away. But Jack was not to be so easily suppressed.

"But, surely," he urged, "you would be doing no harm in telling us if a foreign gentleman called here last night?"
