The sleeping-potion was already taking effect. The old woman drowsily opened her eyes:

"No," she said; "nothing else. You're a good girl, Natty, and it was wrong to do it; but I'll make it all right, Natty; I'll make it all right!"

They were the last words she ever spoke! Nathalie wondered what she meant, as she went into her own room, and lit her lamp.

The storm without was raging fast and furious; the blaze of the lightning filled the room with a lurid blue glare, the dull and ceaseless roll of the thunder was appalling, and the rain lashed the windows in torrents.

"Heaven help any poor wanderer exposed to such a tempest!" Nathalie thought.

If she had only known of him who cowered under the spruce bushes on Redmon road, waiting for it to subside.

Nathalie brushed out her long, shining, showering curls, bathed her face, and said her prayers. The furious and short-lived tempest had raged itself out by that time, and she blew out the lamp and sat down by the window—it was too hot to go to bed. She made a pile of the pillows, and leaned her head against them where she sat; and, with the rushing rain for her lullaby, fell asleep.

What was that? She awoke with a start. She knew she had not slept long, but out of a disturbed dream some noise awoke her—a sharp metallic sound. Her room was weirdly lighted by the faint rays of the wan and spectral moon, and with her heart beating thick and fast she listened. The old house was full of rats—she could hear them scampering over her head, under her feet, and between the partitions. It was this noise that had awoke her; the trees were writhing and groaning in the heavy wind, and tossing their green arms wildly, as if in some dryad agony—perhaps it was that. She listened, but save these noises all was still. Yes, it was the rats, Nathalie thought, and settling back among the pillows once more, she fell into another light slumber.

No, Nathalie. Neither the wailing wind, nor the surging trees, nor the scurrying rats made the noise you heard. In the corridor outside your room a tall, dark figure, with a black crape mask on its face, is standing. The figure wears a long overcoat and a slouched hat, and it is fitting a skeleton key in the lock of Mrs. Leroy's door; for Nathalie has locked that door. Like some dark and evil spirit of the night, it glides into the chamber; the lamp on the table burns low, and the old woman sleeps heavily. Softly it steals across the room, lays hold of the japanned tin box, tries key after key from a bunch it carries, and at last succeeds. The box is open—the treasure is found. Fifty—fifty—fifty! they are all fifties—fifty-pound notes on good and sound Speckport banks. The eyes behind the mask glitter—the eager hands are thrusting the huge rolls into the deep pockets of the overcoat. But he drops the last roll and stops in his work aghast, for there is an awful sound from the bed. It is not a scream, it is not a cry; but something more awful than ever came from the throat of woman in all the history of woman's agony. It is like the death-rattle—hoarse and horrible. He turns and sees the old woman sitting up in bed, one flickering finger pointing at him, the face convulsed and livid, the lips purple and foaming, the eyes starting. One cry, and all for which he has risked so much will be lost! He is by the bedside like a flash; he has seized one of the pillows, and hurled her back; he has grasped her by the throat with one-powerful hand, while with the other he holds the pillow over her face. Fear and fury distort his own—could you see it behind the mask—and his teeth are set, and his eyeballs strained. There is a struggle, a convulsive throe, another awful rattle in the throat, and then he sees the limbs relax, and the palpitating throat grow still. He need fear no cry now; no sound will ever again come from those aged lips; the loss or gain of all the treasures in the wide earth will never disturb her more. He loosens his grasp, removes the pillow, and the lamplight falls on a horrible sight. He turns away with a shudder from that blackened and convulsed visage, from the starting eyes forced out of their sockets, and from the blood which trickles in a slow, dreadful stream between purple lips. He dare not stop to look or think what he has done; he thrusts the last roll into his pocket and flies from the room. He is so furiously impatient now to get away from that horrible thing on the bed, that he forgets caution. He flies down the stairs, scarcely knowing that the noise he makes echoes from cellar to attic of the silent old house. He takes the wrong turning, and swears a furious oath, to find himself at a door instead of the window by which he had entered. He hears a shriek, too; and, mad with terror, tears off his mask and turns down another passage. Right at last! this is the window! He leaps through it—he is out in the pale moonlight, tearing through the trees like a madman. He has gained the road—a horse stands tied to a tree, and he leaps on his back, drives his spurs furiously into the beast's side, and is off like the wind. In ten minutes, at this rate, he will be in Speckport, and safe.
