CHAPTER III

MARGARET LANGMORE

As Raymond Case had said, the Langmore mansion was a large one, setting in the midst of an extensive lawn, sprinkled here and there with maples and oaks and fine flowering bushes. The hedge in front was well kept and the side fences were also in good repair. In the rear was a stable and also an automobile shed, for the late master of this estate had been fond of a dash in his runabout when time permitted. Down by the brook, back of the stable, was a tiny wharf, where a boat was tied up, a craft which Margaret Langmore had occasionally taken down to the river for a row.

The mansion now looked dark and lonesome, although many folks passed on the highway and whispered to each other that there was the spot where the gruesome tragedy had been committed. "And to think that the man's own daughter did it," they would generally add. "Beats all how bloodthirsty some folks can get. He must have cut her short on money or something and she was too high-strung to stand it."

"No, it ain't that," another would answer. "She's been flirting around with a certain young man, a Wall Street gambler, and her mother wouldn't have it and told her so. That's the real trouble, my way of thinking."

Inside of the house all was as quiet as a tomb save for the ticking of the long clock in the lower hall. Below, a single policeman was on guard, in company with a woman, who had been sent in to help: Upstairs another woman was stationed, to see that Margaret Langmore might not take it upon herself to leave for parts unknown.

Margaret sat in her own room, in the wing on the second floor, a dainty apartment, trimmed in blue and containing all her girlish treasures. On the walls were numerous photographs of her old schoolmates and the flag of the seminary she had attended. And on the mantel rested the picture of Raymond Case, the high polish of the surface marred in one spot where a tear had fallen upon it.

The girl was tall and slender, with a wealth of light-brown hair and eyes of deepest blue. It was more than a pretty face, for it had a certain sadness that was touching.

For several minutes the girl had not moved. Now, as the door opened and the woman who was on guard upstairs came in, she gave a long sigh.
