"The stables are always locked, and the men in bed by ten o'clock," she murmured, "when we are at home. It will make a terrible hubbub to get a carriage ready; but yet I dare say one of the servants could manage the matter quietly for me."

"But why should you go to-night, my lady?" cried Phoebe Marks. "To-morrow will do quite as well. A week hence will do as well. Our landlord would take the man away if he had your promise to settle the debt."

Lady Audley took no notice of this interruption. She went hastily into the dressing-room, and flung off her bonnet and cloak, and then returned to the boudoir, in her simple dinner-costume, with her curls brushed carelessly away from her face.

"Now, Phoebe Marks, listen to me," she said, grasping her confidante's wrist, and speaking in a low, earnest voice, but with a certain imperious air that challenged contradiction and commanded obedience. "Listen to me, Phoebe," she repeated. "I am going to the Castle Inn to-night; whether it is early or late is of very little consequence to me; I have set my mind upon going, and I shall go. You have asked me why, and I have told you. I am going in order that I may pay this debt myself; and that I may see for myself that the money I give is applied to the purpose for which I give it. There is nothing out of the common course of life in my doing this. I am going to do what other women in my position very often do. I am going to assist a favorite servant."

"But it's getting on for twelve o'clock, my lady," pleaded Phoebe.

Lady Audley frowned impatiently at this interruption.

"If my going to your house to pay this man should be known," she continued, still retaining her hold of Phoebe's wrist, "I am ready to answer for my conduct; but I would rather that the business should be kept quiet. I think that I can leave this house without being seen by any living creature, if you will do as I tell you."

"I will do anything you wish, my lady," answered Phoebe, submissively.

"Then you will wish me good-night presently, when my maid comes into the room, and you will suffer her to show you out of the house. You will cross the courtyard and wait for me in the avenue upon the other side of the archway. It may be half an hour before I am able to join you, for I must not leave my room till the servants have all gone to bed, but you may wait for me patiently, for come what may I will join you."

Lady Audley's face was no longer pale. An unnatural luster gleamed in her great blue eyes. She spoke with an unnatural rapidity. She had altogether the appearance and manner of a person who has yielded to the dominant influence of some overpowering excitement. Phoebe Marks stared at her late mistress in mute bewilderment. She began to fear that my lady was going mad.
