Would he never end?  Would he never let go of her hand? never let her get away to the Nile, to that barbarous music?

“I think we were getting close to each other then.  But—­but I think we are much closer now.  Don’t you?”

“Yes,” she managed to say.

“Closer because I’ve proved you; I’ve proved you through all this dreadful illness.”

His hand gripped hers more firmly.

“But you, perhaps, haven’t proved me yet as I have proved you.”

“Oh, I don’t doubt your—­”

“No, but I want you to know, to understand me as I believe I understand you.  And that’s why I’m going to tell you something, something very—­frightful.”

There was a solemnity in his voice which held, which startled her.

“Frightful?” she almost whispered.

“Yes.  I didn’t mean ever to tell you.  But somehow, when you came back to-day, came hurrying back to me so quickly, without even doing what you went away to do, somehow I began to feel as if I must tell you, as if I should be a cad not to, as if it was your right to know.”

She said nothing.  She had no idea what was coming.

“It is your right to know.”

He paused.  Now he was not looking at her, but straight before him into the darkness.

“Last night Isaacson and I were here.”

At the Doctor’s name she moved.

“I had asked him to tell me what my illness had been, what I had been suffering from.  He said he would tell me.  This was before.”

Now again he looked at her.

She formed “Yes” with her lips.

“When we were out here after dinner, I asked him again to tell me.  I had had your telegram then.”

She nodded.

“He knew you were coming back a day sooner than we had expected.”

She nodded again.

“And he told me.  I am going to tell you what he said.  He said that I had been poisoned”—­her hand twitched beneath his—­“by a preparation of lead, administered in small doses through a long period of time.”

“Poisoned!”

“Yes.”

“And—­and you believe such a thing?”

“Yes.  In such matters Isaacson knows.”

“Poisoned!” she repeated.

She said the word without the horror he had expected, dully, mechanically.  He thought perhaps she was dazed by surprise.

“But that’s not all,” he said, still holding her hand closely.  “I asked him who on board the Loulia could have wished for my death.”

“That’s—­that’s just what I was thinking,” she managed to say.

“And then he said a dreadful thing.”

“What?”

“He said that you had done it.”

She took her hand away from his sharply, and sat back in her chair.  He did not move.  They sat there looking at each other.  And their silence was disturbed by the perpetual singing on the Loulia.

And so it had been said!
