Mrs. Cowels sat for a long while looking at the cheque, turning it over and reading the figures aloud to Bennie and explaining to him what an enormous amount of money it was. And what a load had thus been lifted from the slender shoulders of this lone woman! Now she could pay off the mortgage and have nearly fourteen hundred dollars left. It seemed to her that that amount ought to keep them almost for a lifetime. This relief, coming so unexpectedly, had made her forget for the moment her great sorrow. She even smiled when telling Bennie how very rich they were, but when the boy looked up, with tears swimming in his big, blue eyes, and said, through the sobs that almost choked him: "But I'd ruther have papa back again," it pierced her heart and made the old wound bleed anew. Patsy Daly and his friend, the Philosopher, were at that moment approaching the Cowels's house where they lodged--they were room-mates now. They had seen the two men leaving the house, and having caught sight of the lonely woman and her child, stood looking beneath the window shade upon the pathetic scene. When they saw the official envelope, with the big, red seal, they readily guessed the errand of the men, for they knew the rules and ways of the Brotherhood, and that the dead engineer's family was entitled to the insurance upon his life. They saw the little mother smiling upon her boy, saw him turn a tearful face up to hers, and the change that came, and the look of anguish upon the unhappy woman's face touched them deeply. "O God!" said the Philosopher, laying a hand upon the shoulder of his friend, "if it be true that we, who are so wicked, must suffer for our sins, it is pleasant to feel that these martyrs--the millions of mothers whose hearts are torn in this world--will have a pleasant place in the world to come." CHAPTER EIGHTEENTH Mr. Watchem, chief of the famous Watchem detective agency, was pacing his private office. He was a heavy man with heavy features and a heavy, dark mustache, at which he tugged vigorously as he walked. In his left hand he carried a dozen or more sheets of closely written note paper. Presently the door opened, and a small man, slightly stooped, entered and removed his hat. "Is this your report, sir?" asked the chief. The man said it was. "And can you substantiate these charges? Mind you, if an innocent man suffers I shall hold you accountable, do you understand?" "I understand, and I am willing to swear to that statement." "Have the men been arrested?" "They have, and are now on their way to Chicago." "They will probably be arraigned to-morrow morning," observed the great detective. "See that your witnesses are on hand--you may go now." When the small man had stolen softly out, down the stair and into the street, the chief detective descended, entered a closed carriage and was driven to his home.
