Standing in the doorway and groping with her hands held out before her as if she were blind, was a woman. Her gown was the tawdry half-dress of the dance-halls, and the wrap over her bare shoulders was a gaudy imitation in colors of the Spanish mantilla. Her head was without covering, and her hair, which was luxuriant, hung in disorder over her face. One glance at the eyes, fixed and staring, assured Lidgerwood instantly that he had to do with one who was either drink-maddened or demented. "Where is he?" the intruder asked, in a throaty whisper, staring, not at him, as Lidgerwood was quick to observe, but straight ahead at the portieres cutting off the state-room corridor from the open compartment. And then: "I told you I would come, Rankin; I've been watching years and years for your car to come in. Look--I want you to see what you have made of me, you and that other man." Lidgerwood sat perfectly still. It was quite evident that the woman did not see him. But his thoughts were busy. Though it was by little more than chance, he knew that Hallock's Christian name was Rankin, and instantly he recalled all that McCloskey had told him about the chief clerk's marital troubles. Was this poor painted wreck the woman who was, or who had been, Hallock's wife? The question had scarcely formulated itself before she began again. "Why don't you answer me? Where are you?" she demanded, in the same husky whisper; "you needn't hide--I know you are here. _What have you done to that man?_ You said you would kill him; you promised me that, Rankin: have you done it?" Lidgerwood reached up cautiously behind him, and slowly turned off the gas from the bracket desk-lamp. Without wishing to pry deeper than he should into a thing which had all the ear-marks of a tragedy, he could not help feeling that he was on the verge of discoveries which might have an important bearing upon the mysterious problems centring in the chief clerk. And he was afraid the woman would see him. But he was not permitted to make the discoveries. The woman had taken two or three steps into the car, still groping her way as if the brightly lighted interior were the darkest of caverns, when some one swung over the railing of the observation platform, and Superintendent Leckhard appeared at the open door. Without hesitation he entered and touched the woman on the shoulder. "Hello, Madgie," he said, not ungently, "you here again? It's pretty late for even your kind to be out, isn't it? Better trot away and go to bed, if you've got one to go to; he isn't here." The woman put her hands to her face, and Lidgerwood saw that she was shaking as if with a sudden chill. Then she turned and darted away like a frightened animal. Leckhard was drawing a chair up to face Lidgerwood. "Did she give you a turn?" he asked, when Lidgerwood reached up and turned the desk-lamp on full again.
