“They are all posted in London, I think you told me?” added Mr Auriol.

“To be sure,” said Mr Morison. “Yes. I have once or twice wondered who does it, unless it is himself? No, by-the-by, he has distinctly said he is not in London. I have thought of it, but not very much. I fancied it so hopeless to get any clue in that way.”

“But it must be some one in his confidence, some one, I should almost say, whom he had a claim on,” said Godfrey. “For there is a certain amount of risk in doing it; the person might be blamed for having taken any part in it. Is there no one any of you have ever heard of who would be likely to agree to do Arthur a service of the kind?” He looked round, but his glance seemed to rest on Lettice. No one spoke.

“You must all think it over,” he said. “It’s only a suggestion, but something may come of it.” And soon after, allowing that he was very tired, he said “Good night,” and went away.

Lettice, in the quiet of her own room, realised how kindly and considerately he had behaved. His matter-of-fact manner had been the greatest relief, and nothing that he could have said could have been so full of tact and delicacy as his saying nothing.

“I do believe,” thought the girl, her impulsive nature aglow again, “I do believe he hurried out here to-night as much for my sake as on account of his anxiety. He knew his coming in that sudden unlooked-for way would carry off the awkwardness. It is very generous of him.” Then her thoughts reverted to what he had suggested. Did she know any one standing in such a position to Arthur? She sat long thinking, asking herself the question, when suddenly, by that curious process by which it sometimes seems as if the machinery of our brain obeyed our orders unconsciously to ourselves—there dashed into her memory a name, a sentence she had heard Arthur utter. The name was “Dawson,” and as she repeated it to herself, she seemed to hear her brother’s voice saying thoughtfully—

“Yes, I do believe there’s one person in the world who’d do anything for me. It’s that fellow Dawson. I’ve told you about him, Lettice?” Yes, he had told her about him, though he probably had forgotten doing so, just as she, till this moment, had forgotten having heard it. Now, by slow degrees, it came back to her. Dawson had been a young servant in Mr Downe’s service, and by a fall from a ladder had broken his leg. Being naturally delicate, this accident had altogether ruined his health; he was pronounced incurably lame, and Arthur had done his utmost to help and comfort the poor boy. I do not know that Lettice remembered all these details so clearly, but they were the facts, and she recalled enough to make her sure that Dawson was worth looking up. She knew he had been living at the little town near to which was Mr Downe’s “cramming” establishment; she felt almost sure his home was there. In any case, it was more than probable he would there be heard of; and surely, surely it was worth trying!

Whatever were Lettice Morison’s faults and failings, want of courage and determination were not among them. Her plans were soon made.

It was but little sleep that fell to her share that night.

“I must go alone,” she said to herself. “If I have discovered Arthur’s secret I have no right to share it with any other till I know what he himself wishes. Besides, it is I who am to blame for his having been driven away; it is I who should bring him back.”
