“The chief agrees with me that the murder of Professor Warren is going to make a great deal of comment. He will have the inquest to-morrow, and hopes before then to have something to go on. As it stands now all we know is that Warren was murdered, but nothing else. The—” There came a commotion at the door, and we turned, only to see the housekeeper rush into the building. Her face was red as if she had been running, but why she had taken so long to come to the library after Carter called up I could not tell. For a second she leaned against the door as if out of breath, and then gave a quick glance around the room. In her eyes was terror, and the glance at length rested upon Carter. With one step in his direction, she gasped in a trembling voice so low that we could barely hear her: “Mr. Warren—is—is he dead?” Carter nodded, and again the woman's eyes swept the room. This time they went slowly as if seeking for something, and as if afraid of what she might find. Suddenly she stiffened into attention as her glance fell upon the foot of the dead man, which could be seen around the desk. Then slowly, a step at a time, she crossed the floor to a place beyond the desk. There she stood, silently looking down at the still figure of her employer. The red had faded from her cheeks, and her face was a dull white. Slowly she turned, her eyes asking the question before her lips spoke: “Was he murdered?” came the quivering voice. “Yes,” some one said. For a moment she did not speak. Again her eyes came back to the silent figure. For an instant as her lips moved I thought she would speak, but she gave a shudder and shut them tightly. But the flush had come back to her face, and when she turned toward us, I could see the veins in her forehead throb. And then suddenly, in a shrill voice which rang through the room, she shrieked: “I knew it, I knew it. It's that secretary. I knew that girl would—” But the sentence was not completed. As the shrill voice rose higher and higher, her hands began to beat the air; the voice died away in her throat as if suddenly cut off. Then with a little gasp she staggered a second and fell fainting to the floor. Chapter IV We Discuss the Crime So unexpected was the woman's action that for a second none of us stirred. It was the doctor who reached her first. The eyes opened with a little flutter, and the color came flooding back into her cheeks. As he placed her in a chair, her hands went out in a confused, questioning gesture, as if seeking aid. Then when she realized what had happened, she cast one horrified look in the direction of the body.
