The Witness for the Defence by A.E.W. Mason

But Stella's confidence did not live long. Mr. Hazlewood was a child at deceptions; and day by day his anxieties increased. His friends argued with him -- his folly and weakness were the themes -- and he must needs repel the argument though his thoughts echoed every word they used. Never was a man brought to such a piteous depth of misery by the practice of his own theories. He sat by the hour at his desk, burying his face amongst his papers if Dick came into the room, with a great show of occupation. He could hardly bear to contemplate the marriage of his son, yet day and night he must think of it and search for expedients which might put an end to the trouble and let him walk free again with his head raised high.

But there were only the two expedients. He must speak out his fears that justice had miscarried, and that device his vanity forbade; or he must adopt Pettifer's suggestion, and from that he shrank almost as much. He began to resent the presence of Stella Ballantyne and he showed it. Sometimes a friendliness, so excessive that it was almost hysterical, betrayed him; more usually a discomfort and constraint. He avoided her if by any means he could; if he could not quite avoid her an excuse of business was always on his lips.
