Up till now she had not admitted that anything could make a difference, that anything could touch, could alter by a shade the safe, the intangible, the unique relation between her and Rodney. It was proof against anything that anybody could think. And the Powells were not given to thinking things. Agatha's own mind had been a crystal without a flaw, in its clearness, its sincerity.
It had to be to ensure the blessed working of the gift; as again, it was by the blessed working of the gift that she had kept it so. She could only think of that, the secret, the gift, the inexpressible thing, as itself a flawless crystal, a charmed circle; or rather, as a sphere that held all the charmed circles that you draw round things to keep them safe, to keep them holy.
She had drawn her circle round Rodney Lanyon and herself. Nobody could break it. They were supernaturally safe.
And yet the presence of the Powells had made a difference. She was forced to own that, though she remained untouched, it had made a difference in him. It was as if, in the agitation produced by them, he had brushed aside some veil and had let her see something that up till now her crystal vision had refused to see, something that was more than a lurking possibility. She discovered in him a desire, an intention that up till now he had concealed from her. It had left its hiding place; it rose on terrifying wings and fluttered before her, troubling her. She was reminded that, though there were no lurking possibilities in her, with him it might be different. For him the tie between them might come to mean something that it had never meant and could not mean for her, something that she had refused not only to see but to foresee and provide for.
She was aware of a certain relief when Monday came and he had left her without any further unveilings and revealings. She was even glad when, about the middle of the week, the Powells came with a cart-load of luggage and settled at the Farm. She said to herself that they would take her mind off him. They had a way of seizing on her and holding her attention to the exclusion of all other objects.
She could hardly not have been seized and held by a case so pitiful, so desperate as theirs. How pitiful and desperate it had become she learned almost at once from the face of her friend, the little pale-eyed wife, whose small, flat, flower-like features were washed out and worn fine by watchings and listenings on the border, on the threshold.
Yes, he was worse. He had had to give up his business (Harding Powell was a gentle stockbroker). It wasn't any longer, Milly Powell intimated, a question of borders and of thresholds. They had passed all that. He had gone clean over; he was in the dreadful interior; and she, the resolute and vigilant little woman, had no longer any power to get him out. She was at the end of her tether.
Agatha knew what he had been for years? Well—he was worse than that; far worse than he had been, ever. Not so bad though that he hadn't intervals in which he knew how bad he was, and was willing to do everything, to try anything. They were going to try Sarratt End. It was her idea. She knew how marvellously it had answered with dear Agatha (not that Agatha ever was, or could be, where he was, poor darling). And besides, Agatha herself was an attraction. It had occurred to Milly Powell that it might do Harding good to be near Agatha. There was something about her; Milly didn't know what it was, but she felt it, he felt it—an influence or something, that made for mental peace. It was, Mrs. Powell said, as if she had some secret.
She hoped Agatha wouldn't mind. It couldn't possibly hurt her. He couldn't. The darling couldn't hurt a fly; he could only hurt himself. And if he got really bad, why then, of course, they would have to leave Sarratt End. He would have, she said sadly, to go away somewhere. But not yet—oh, not yet; he wasn't bad enough for that. She would keep him with her up to the last possible moment—the last possible moment. Agatha could understand, couldn't she?
Agatha did indeed.
