David did not recognise whither the question led. "Why, yes," he said mechanically. Mr. Haddon held out the slip of paper. "According to this memorandum in Mr. Morton's hand, the money was in the safe the day before his death." His eyes screwed into David. "Perhaps you can suggest to us what became of the money." David stared at him blankly. "The money—was there—when Morton died!" said Dr. Thorn amazedly. He looked from one man to the other. Then understanding came into his face, and a great relief. "You mean—Mr. Aldrich—took it?" "I took it!" David repeated stupidly. He turned slowly to Helen. Her white face, with its wide eyes and parted lips, and the sudden look of fear she held upon him, cleared his head, made him see where he was. "I did not take the money!" he cried. "No, of course not," returned Mr. Haddon grimly. "But who did?" "If I'd taken it, wouldn't I have disappeared? Would I have been such a fool as to have stayed here to be caught?" "If the thief had run away, that would have fastened the guilt on him at once. To remain here, hoping to throw suspicion on Mr. Morton—this was the cleverest course." "I did not take the money!" David cried desperately. "It's a lie!" Helen moved to David's side, and gazed straight into Mr. Haddon's accusing face. Indignation was replacing her astoundment; her cheeks were tingeing with red. "What, would you condemn a man upon mere guess-work!" she cried. "Merely because the money is not there, is that proof that Mr. Aldrich took it? Do you call this justice, Mr. Haddon?" Mr. Haddon's look did not alter, and he did not reply. The opinion of womankind he had ever considered negligible. Helen turned to David and gave him her hand. "I believe you." He thanked her with a look. "It must have been Mr. Morton," she said.
