She haunted the depots of the city, and was lucky enough to see him when he took passage. Quietly boarding the same train, she bided her time, intent on gaining possession of the detective's sister for purposes of her own. The fires of insanity were already burning in the brain of the convict's wife. Revenge for past wrongs seemed the sole object of her life now, and this was the incentive that placed her on the track of a fleeing villain and his intended victim. Madge saw Ruggles when he left the car. She watched her opportunity, and lifting the partially insensible girl, bore her swiftly to the outside, as the train halted for a minute. She gave vent to a chuckle as the train went thundering on its course. She had passed from the cars on the opposite side from the depot, and consequently was able to elude the gaze of the depot agent. Along the track she went, pausing at times to rest, until she was fully a mile from the station. In the shadow of a clump of trees the hag came to a halt and deposited her burden on the ground. A moan from the drugged and helpless Nell reached her ears. And then Mrs. Scarlet chuckled the louder. "Good; she's coming out of her bad spell. I want her to realize her fate, else there wouldn't be the least bit of pleasure in my revenge." Removing veil and light cloak, Mrs. Scarlet gazed down into the pallid face of poor Nell, with only hatred gleaming from her sunken, beady eyes. "Ho! I've outwitted the master devil himself, and now I will have you all to myself, to deal with in a way that will cut to the quick when Dyke Darrel hears of it." Nell had on only a light summer robe under the shawl. She looked very innocent and beautiful as she lay there under the gaze of that human hyena. "Pretty's a picture," hissed the wicked Madge. "I'll all the more delight in seeing you suffer. Ah! she is coming out of her stupor. How do you feel, dear?" Nell had opened her eyes and gazed at the wicked face above her, in a dazed semi-consciousness. No answer was vouchsafed. Then, in looking about, the gleam of steel lines under the moon's rays seemed to attract the notice of Mrs. Scarlet for the first time--the straight lines that marked the course of the Erie road. Their glitter seemed to offer a diabolical suggestion to Madge Scarlet. "Ha! I have it." Springing to her feet, she laid her arms about the slender form of the helpless girl, and, lifting her, walked swiftly to the railway track. In the centre, between the rails, she deposited her burden. "Revenge! sweet revenge!" cackled the hag in a blood-curdling voice. Again the girl moved and moaned; yet she seemed unable to change her position. "Rest yourself comfortably, my girl; you won't be in trouble long," muttered the demon woman, with a grin that was absolutely sickening. Poor Nell! She lay quite still after that, between the fatal rails, only giving sign of life by a faint moan occasionally.
