She turned up the lamp so that the light fell full upon the page. He bent closer. On the margin, so blurred as to be almost indecipherable, he saw his wife's sign, a square of delicate script. To a careless reader it might have seemed to have been written with a light pencil and to have been meant to stand. Examined closely it revealed the firm strokes of a heavy lead obliterated with india-rubber. Gertrude's finger slid away and left him free to turn the pages. There were several of these marks in the same handwriting, each one deliberately erased. The manuscript had been in his wife's hand within the last three days; for three days certainly Tanqueray had been in Chagford, and for three weeks for all Brodrick knew. There was no reason why he should not be there, no reason why they should not be together. Then why these pitiable attempts at concealment, at the covering of the tracks? And yet, after all, they had not covered them. They had only betrayed the fact that they had tried. Had they? And which of them? Tanqueray in the matter of obliteration would at any rate have been aware of the utter inadequacy of india-rubber. To dash at a thing like india-rubber was more the sudden, futile inspiration of a woman made frantic by her terror of detection. It was clear that Jane had not wanted him to know that Tanqueray was at Chagford. She had not told him. Why had she not told him? She knew of the plight they were in at the office, of the hue and cry after the unappearing manuscript. So his brain worked, with a savage independence. He seemed to himself two men, a man with a brain that worked, following a lucid argument to an obscure conclusion, and a man who looked on and watched its working without attaching the least importance to it. It was as if _this_ man knew all the time what the other did not know. He had his own light, his own secret. He had never thought about it before (his secret), still less had he talked about it. Thinking about it was a kind of profanity; talking would have been inconceivable sacrilege. It was self-evident as the existence of God to the soul that loves him; a secret only in that it was profounder than appearances, in that it stood by the denial of appearances, so that, if appearances were against it, what of that? He was thinking about it now, obscurely, without images, barely with words, as if it had been indeed a thing occult and metaphysical. Thinking about it--that meant, of course, that he had for a moment doubted it? It was coming back to him now, clothed with the mortal pathos of its imperfection. She was dearer to him--unspeakably dearer, for his doubt. The man with the brain approached slowly and unwillingly the conclusion that now emerged, monstrous and abominable, from the obscurity. If that be so, he said, she is deliberately deceiving me.
