“Is Luke Hatton in attendance upon her?”

“In constant attendance,” she rejoined.  “That man has obeyed you well, my Lord.  But take heed of him:  he is a dangerous weapon, and may injure the hand that employs him.  Strike gently upon that bell.  He will attend the summons.”

Lord Roos complied; when, to his astonishment and dismay, the curtains shrouding the entrance to the adjoining room were drawn aside, and Lady Lake stalked from behind them.  Never before had she surveyed her son-in-law with such a glance of triumph as she threw upon him now.

“You were mistaken you see, Elizabeth,” said Lord Roos to his lady.  “Your mother needs no aid.  She is perfectly well.”

“Ay, well enough to confound you and all your wicked purposes, my Lord,” cried Lady Lake.  “You have not accomplished my destruction, as you perceive; nor shall you accomplish your wife’s destruction, though you have well-nigh succeeded.  Let it chafe you to madness to learn that I possess an antidote, which I have myself approved, and which will kill the poison circling in her veins, and give her new life.”

“An antidote!” exclaimed Lord Roos.  “So far from galling me to madness, the intelligence fills me with delight beyond expression.  Give it me, Madam, that I may administer it at once; and heaven grant its results may be such as you predict!”

“Administered by you, my Lord, it would be poison,” said Lady Lake, bitterly.  “But you may stand by and witness its beneficial effects.  They will be instantaneous.”

“As you will, Madam, so you do not delay the application,” cried Lord Roos.

“Drink of this, my child,” said Lady Lake, after she had poured some drops of the cordial into a glass.

“I will take it from no hand but my husband’s,” murmured Lady Roos.

“How?” exclaimed her mother, frowning.

“Give it me, I say, Madam,” cried Lord Roos.  “Is this a time for hesitation, when you see her life hangs upon a thread, which you yourself may sever?”

And taking the glass from her, he held it to his wife’s lips; tenderly supporting her while she swallowed its contents.

It was not long before the effects of the cordial were manifest.  The deathly hue of the skin changed to a more healthful colour, and the pulsations of the heart became stronger and more equal; and though the debility could not be so speedily repaired, it was apparent that the work of restoration had commenced, and might be completed if the same treatment were pursued.

“Now I owe my life to you, my dear Lord,” said Lady Roos, regarding her husband with grateful fondness.

“To him!” exclaimed her mother.  “You owe him nothing but a heavy debt of vengeance, which we will endeavour to pay, and with interest.  But keep calm, my child, and do not trouble yourself; whatever may occur.  Your speedy restoration will depend much on that.”

“You do not adopt the means to make me calm, mother,” replied Lady Roos.
