"You already hold a secret of mine," he said, "and I am about to make you a present of another. The man who drugged me that night six months ago is Major Strause."
Mollie had too much self-control to show the surprise which filled her.
"I have something I want to tell you," continued Keith. "Can I see you somewhere alone?"
"Gavon, the music is going to begin again; do stop talking," cried Kitty, in a restless voice.
A girl who made her name at that concert came to the front of the stage, and her magnificent organ-like notes filled the building. Mollie, however, much as she loved music, scarcely listened. It was not only the tone in Gavon Keith's voice, but the words which he had uttered, which filled her mind. Something was undoubtedly wrong.

"I shall be in the front drawing-room to-night at seven," he said. "Can you come down a few moments before the rest of the party?"
"I ought not," was Mollie's response.
"I ask it as a favour—a great personal favour. Will you refuse me?"
