Haggard anxiety and remorse are bad companions to be barred up with. Brooding all day, and resting very little indeed at night, will not arm a man against misery. Next morning, Clennam felt that his health was sinking, as his spirits had already sunk and that the weight under which he bent was bearing him down.

Night after night he had risen from his bed of wretchedness at twelve or one o'clock, and had sat at his window watching the sickly lamps in the yard, and looking upward for the first wan trace of day, hours before it was possible that the sky could show it to him. Now when the night came, he could not even persuade himself to undress.

For a burning restlessness set in, an agonised impatience of the prison, and a conviction that he was going to break his heart and die there, which caused him indescribable suffering. His dread and hatred of the place became so intense that he felt it a labour to draw his breath in it. The sensation of being stifled sometimes so overpowered him, that he would stand at the window holding his throat and gasping. At the same time a longing for other air, and a yearning to be beyond the blind blank wall, made him feel as if he must go mad with the ardour of the desire.

Many other prisoners had had experience of this condition before him, and its violence and continuity had worn themselves out in their cases, as they did in his. Two nights and a day exhausted it. It came back by fits, but those grew fainter and returned at lengthening intervals. A desolate calm succeeded; and the middle of the week found him settled down in the despondency of low, slow fever.

With Cavalletto and Pancks away, he had no visitors to fear but Mr and Mrs Plornish. His anxiety, in reference to that worthy pair, was that they should not come near him; for, in the morbid state of his nerves, he sought to be left alone, and spared the being seen so subdued and weak. He wrote a note to Mrs Plornish representing himself as occupied with his affairs, and bound by the necessity of devoting himself to them, to remain for a time even without the pleasant interruption of a sight of her kind face. As to Young John, who looked in daily at a certain hour, when the turnkeys were relieved, to ask if he could do anything for him; he always made a pretence of being engaged in writing, and to answer cheerfully in the negative. The subject of their only long conversation had never been revived between them. Through all these changes of unhappiness, however, it had never lost its hold on Clennam's mind.
