I own, I felt some pleasure on hearing him interrupted by the voice of my strange adviser. 'If Miss Percy will trust to me,' said he, 'I shall engage to place her in her carriage, in one tenth part of that time.'
'Trust you!' cried Lord Frederick very angrily.—'And who are you?'
'Miss Percy's guard for the present,' answered the mask dryly.
'Her guard!' exclaimed Lord Frederick. 'From whom?'
'From you, my Lord, if you make it necessary,' retorted the stranger.
'Oh mercy,' interrupted Miss Arnold, 'here will be a quarrel:—do, for heaven's sake, Ellen, let us be gone.'
'Do not alarm yourself, young lady,' said the stranger, in a sarcastic tone; 'the dispute will end very innocently. Miss Percy, let me lead you to your carriage; or, if you prefer remaining here while I go in search of it, for once show yourself firm, and resist every attempt to entice you from this spot.'
I embraced the latter alternative, and the stranger left us. The moment he was gone, Miss Arnold began to wonder who the impudent officious fellow could be, and to enquire whether we were to wait his pleasure in the lobby for the rest of the night. She protested her belief, that I had been infected by that precise old maid Miss Mortimer; and could by no means imagine what was my objection to Lord Frederick's carriage. I coldly persisted in preferring my own, though my suspicions were staggered by the readiness with which Lord Frederick appeared to acquiesce in my decision. Notwithstanding his impatience at the stranger's first interference, he now treated the matter so carelessly, that my doubts were fast giving ground, when the black domino returned, followed by one of my servants, who informed me that my carriage was now easily accessible.
Leaving Lord Frederick to Miss Arnold, I gave my hand to my mysterious guardian; and, curiosity mingling with a desire to show some little return of civility, I enquired, whether he would allow me to set him down. The stranger declined; but, offering to escort me home, took his place by my side; giving orders to a servant in a plain but handsome livery, that his chariot should follow him to Mr Percy's.
During our drive, I was occupied in endeavouring to discover the name of my unknown attendant, and the means by which he had gained his intelligence. Upon the first point he was utterly impracticable. Upon the second, he frankly declared, that having no business at the masquerade, except to watch me and those with whom I appeared connected for the evening, he had, without difficulty, traced all our motions; but why he had chosen such an office he refused to discover. When he again mentioned the intended expedition to Scotland, Miss Arnold averred that she was lost in astonishment, and asserted her utter incredulity. I too expressed my doubts; alleging, that Lord Frederick could not believe me weak enough to acquiesce in such an outrage. 'As I have not the honour of Miss Percy's acquaintance,' returned the stranger dryly, 'I cannot determine, whether a specious flatterer had reason to despair of reconciling her to a breach of propriety.' The glow of offended pride rose to my cheek; but the carriage stopped, and I had no time to reply; for the stranger instantly took his leave.
