"You look as if something were the matter, Mark. And what have you come back for?"

"Oh, I left some papers at home," answered Mark, speaking as carelessly as he could. "There's nothing the matter with me. The fellow drove fast, that's all. I gave him an extra sixpence."

Perhaps Caroline did not deem this communication particularly relevant to the subject. "What made you go away so early, Mark?" she asked. "You never settled anything about Hendon today."

"Well, I don't think I can go," said Mark. "I'll--I'll see later. Hark!"

Mark's "hark" was spoken in echo to a thundering knock at the door. A knock and a ring enough to shake the house down. He looked round at the walls for a moment as if he wanted to make a dash into them; he stepped towards the window, hesitated, and drew away again; finally he opened the door to escape, but too late, for voices were already in the hall. Caroline looked at her husband in wondering dismay.

"Mark, what has come to you?"

"Hush!" whispered Mark, the perspiration welling up to his forehead, as he bent his head to catch the sound from those voices. "Hark! hush!"

"Is Mr. Cray at home?"

"No, sir. He went to the City early this morning." How Mark Cray blessed his servant for the unconscious mistake, he alone could tell. The man had not seen his master come in, and had no idea he was in the house.

"Gone to the City, is he? Are you sure?"
