Mrs. Arnot smiled, as she ever did, at her husband's attempted witticisms; but what he regarded as light, delicate shafts, winged sportively and carelessly, had rather the character of any heavy object that came to hand thrown at her with heedless, inconsiderate force. It is due Mr. Arnot to say that he gave so little thought and attention to the wounds and bruises he caused, as to be unaware that any had been made. He had no hair-springs and jewel-tipped machinery in his massive, angular organization, and he acted practically as if the rest of humanity had been cast in the same mold with himself. But Haldane's act touched him at his most vulnerable point. Not only had a large sum of his money been made away with, but, what was far worse, there had been a most serious irregularity in the business routine. While, therefore, he resolved that Haldane should receive full punishment, the ulterior thought of giving the rest of his employes a warning and intimidating lesson chiefly occupied his mind. Aware of his wife's "unbusinesslike weakness and sentimental notions," as he characterized her traits, he determined not to see her until he had carried out his plan of securing repayment of the money, and of striking a salutary sentiment of fear into the hearts of all who were engaged in carrying out his methodical will. Therefore, with the key of Haldane's room in his pocket, he kept watch and guard during the remainder of the night, taking only such rest as could be obtained on the lounge in his library. At about sunrise two men appeared, and rapped lightly on the library window. Mr. Arnot immediately went out to them, and placed one within a summer-house in the spacious garden at the rear of the house, and the other in front, where he would be partially concealed by evergreens. By this arrangement the windows of Haldane's apartment and every entrance of the house were under the surveillance of police officers in citizen's dress. Mr. Arnot's own personal pride, as well as some regard for his wife's feelings, led him to arrange that the arrest should not be made at their residence, for he wished that all the events occurring at the house should be excluded as far as possible from the inevitable talk which the affair would occasion. At the same time he proposed to guard against the possibility of Haldane's escape, should fear or shame prompt his flight.
