"How did you get this?" he asked, turning it uneasily in his fingers.

"A boy brought it from the station not half an hour after he went."

Percival was silent. A sudden certainty had sprung up in his mind, and it made any attempt at reassuring her little better than a lie. Yet he felt as if his certainty were altogether unfounded. He could assign no reason for it. The truth was, that Bertie himself was the reason, and Percival knew him better than he had supposed.

"Mr. Thorne," said Judith, "don't you hate me for what I've said? Surely you must. Miss Crawford doesn't dream that Bertie has anything to do with this. And you didn't, for I watched your eyes: you never would have thought of him but for me. It is I, his own sister, who have hinted it. He has nobody but me, and when his back is turned I accuse him of being so base, so cruel, so mercenary, that—" She stopped and tried to steady her voice. Suddenly she turned and pointed to the door: "And if he came in there now, this minute—oh, Bertie, my Bertie, if you would!—if he stood there now, I should have slandered him without a shadow of proof. Oh, it is odious, horrible! The one in all the world who should have clung to him and believed in him, and I have thought this of him! Say it is horrible, unnatural—reproach me—leave me! Oh, my God! you can't."

And in truth Percival stood mute and grave, holding the shred of paper in his hand and making no sign through all the questioning pauses in her words. But her last appeal roused him. "No," he said gently, "I can't reproach you. If you are the first to think this, don't I know that you will be the one to hope and pray when others give up?" He took her hands in his: she suffered him to do what he would. "How should Miss Crawford think of him?" he said. "Pray God we may be mistaken, and if Bertie comes back can we not keep silence for ever?"

"I could not look him in the face."

"Tell me all," said Thorne. "Where did he say he was going? Tell me everything. If you are calm and if we lose no time, we may unravel this mystery and clear Bertie altogether before any harm is done. As you say, there is no shadow of proof. Miss Nash may have gone away alone: school-girls have silly fancies. Or perhaps some accident on the line—"

"No," said Judith.

"No? Are you sure? Sit down and tell me all."

She obeyed to the best of her ability. She told him what Bertie had said about the situation he hoped to obtain, and what little she knew about Emmeline's disappearance.
