"Because he was all right when he went away yesterday morning, but when he came home at noon he was different from what I had ever seen him before. He had just that worried look he has now, and he seemed absent-minded. He was in a great hurry to get back, and the head book-keeper tells me he called for the books to be brought into his private office, and that he spent most of the afternoon going through them. He says that about four o'clock he went through the office, and David was sitting before his desk with his head on his hands, and he didn't speak or look up. A little while afterwards they heard the sound of something heavy falling and ran to his room, and he had fallen on the floor." "It does look," Darrell admitted, thoughtfully, "as though this may have been caused by the discovery of some wrong condition of affairs." "Yes, and it must be pretty serious," Mrs. Dean rejoined, "to bring about such results as these." "Well," said Darrell, "we may not be able to arrive at the cause of this for some time. The first thing to be done is to see that you take a good rest; don't have any anxiety; I will look after everything. As soon as it is daylight it would be well to telegraph for Mr. Britton if you know his address, and possibly for Miss Underwood unless he should seem decidedly better." But Mrs. Dean did not know Mr. Britton's address, no word having been received from him since his departure, and with the return of daylight Mr. Underwood had gained so perceptibly it was thought best not to alarm Kate unnecessarily. For the first few days the improvement in Mr. Underwood's condition was slow, but gradually became quite pronounced. Nothing had been heard from Walcott since his sudden leave-taking, but about a week after Mr. Underwood's seizure word was received from him that he was on his way home. As an excuse for his prolonged absence and silence he stated that his father had died and that he had been delayed in the adjustment of business matters. It was noticeable that after receiving word from Walcott the look of anxiety in Mr. Underwood's face deepened, but his improvement was more marked than ever. It seemed as though the powerful brain and indomitable will dominated the body, forcing it to resume its former activity. By this time he was able to move about his room on crutches, and on the day of Walcott's return he insisted upon being placed in his carriage and taken to the office. At his request Darrell accompanied him and remained with him.
