In the morning she found a letter on her breakfast-table, which the maid said Mrs. Powell had left late last evening, after Agatha had gone to bed. Milly wrote: "Dearest Agatha,—Of course I understand. But are we never going to see you again? What was the matter with you last night? You terrified poor Harding.—Yours ever, M. P."
Without knowing why, Agatha tore the letter into bits and burned them in the flame of a candle. She watched them burn.
"Of course," she said to herself, "that isn't sane of me."
And when she had gone round her house and shut all the doors and locked them, and drawn down the blinds in every closed window, and found herself cowering over her fireless hearth, shuddering with fear, she knew that, whether she were mad or not, there was madness in her. She knew that her face in the glass (she had the courage to look at it) was the face of an insane terror let loose.
That she did know it, that there were moments—flashes—in which she could contemplate her state and recognise it for what it was, showed that there was still a trace of sanity in her. It was not her own madness that possessed her. It was, or rather it had been, Harding Powell's; she had taken it from him. That was what it meant—to take away madness.
There could be no doubt as to what had happened, nor as to the way of its happening. The danger of it, utterly unforeseen, was part of the very operation of the gift. In the process of getting at Harding to heal him she had had to destroy not only the barriers of flesh and blood, but those innermost walls of personality that divide and protect, mercifully, one spirit from another. With the first thinning of the walls Harding's insanity had leaked through to her, with the first breach it had broken in. It had been transferred to her complete with all its details, with its very gestures, in all the phases that it ran through; Harding's premonitory fears and tremblings; Harding's exalted sensibility; Harding's abominable vision of the world, that vision from which the resplendent divinity had perished; Harding's flight before the pursuing Terror. She was sitting now as Harding had sat when she found him crouching over the hearth in that horrible room with the drawn blinds. It seemed to her that to have a madness of your own would not be so very horrible. It would be, after all, your own. It could not possibly be one-half so horrible as this, to have somebody else's madness put into you.
The one thing by which she knew herself was the desire that no longer ran underground, but emerged and appeared before her, lit by her lucid flashes, naked and unashamed.
She still knew her own. And there was something in her still that was greater than the thing that inhabited her, the pursuer, the pursued, who had rushed into her as his refuge, his sanctuary; and that was her fear of him and of what he might do there. If her doors stood open to him, they stood open to Bella and to Rodney Lanyon too. What else had she been trying for, if it were not to break down in all three of them the barriers of flesh and blood and to transmit the Power? In the unthinkable sacrament to which she called them they had all three partaken. And since the holy thing could suffer her to be thus permeated, saturated with Harding Powell, was it to be supposed that she could keep him to herself, that she would not pass him on to Rodney Lanyon.
It was not, after all, incredible. If he could get at her, of course he could get, through her, at Rodney.
That was the Terror of terrors, and it was her own. That it could subsist together with that alien horror, that it remained supreme beside it, proved that there was still some tract in her where the invader had not yet penetrated. In her love for Rodney and her fear for him she entrenched herself against the destroyer. There at least she knew herself impregnable.
