Thurso put his hand to his head suddenly, with a wince of pain he could not control. "Yes, on that point that is all," he said. "Let us agree to say nothing more about a most unpleasant subject. But I want to tell you this: I am suffering so hideously at the present moment that I hardly know what I am saying. Agitation and anger, for which you two are responsible, have brought on about the worst attack I ever had. Very likely I should not have taken laudanum from that bottle you threw away; in any case, I should have struggled hard not to. I struggled yesterday, with the result that I allowed Catherine to pour away all I had in the house. But I am not going to struggle now, thank you. The pain is intolerable, and I believe it to have been brought on by what you did. Your interference has not done the slightest good; it has only given me an hour of hell." Then, quite suddenly, his mood changed. "I have said abominable things to you both," he said. "My only excuse is that I am in torments. I beg the forgiveness of both of you." Here was the real Thurso again, looking out like a soul in prison, trying to burst through the bars, and there was a dreadful, hopeless pathos about him. Catherine laid her hand on his shoulder. "Ah, Thurso, of course we forgive you," she said. "But for God's sake don't give up. I suppose you must take this now because of your pain, but say you will go on fighting it again. It's--it's damnation, you know." He looked at her with agonised eyes. "I will do my best," he said. "Now go, please. Make my excuses to the others if I don't appear at dinner. But I expect I shall; I have two hours yet." The women went out together, but before the door was closed they heard the clink of glass. CHAPTER II. It was a chill November afternoon in the autumn of the same year, and Catherine was seated at the table in her sitting-room at Thurso House, surrounded by a plentiful litter of letters and telegrams, writing busily, fiercely almost, as if to absorb herself in what she was doing to the exclusion of other thoughts. Her secretary, to whom she had just finished dictating a pile of business correspondence and letters less private than those she was occupying herself with, had just left her, and Catherine had begun to tackle this great heap of letters which she felt she had better answer herself--inquiries, mainly, from personal friends. She knew she had given herself more to do than it was really needful that she should, but what to her mind was needful was that she should be occupied in writing, and leave herself no leisure to think. At present there was nothing to be gained by thinking; she could take no step.
