"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.
