‘And what is all this to me?’ asked Maxwell, with such admirable self-command that Randolph could not help thinking what a pity it was he did not follow out the profession of state-craft. Nevertheless, every word had struck home, and although his voice was so steady and his face so calm, the perspiration stood on his brow, and there was a dangerous glitter in his deep-set eyes.

‘Why thus much,’ returned Randolph—‘that had this intriguer, whoever he may be, no claims but his own merit to the notice of Mary Carmichael, I believe, and those who know her best affirm, that she would never have condescended to notice him. But these interviews, granted for some hidden purpose unconnected with gallantry, are compromising her till she is gradually falling into his power, and the poor girl will find herself at last compelled to accept as a lover the man for whom she does not care, unless she be extricated from her false position by the man for whom she does.’

‘Meaning me,’ said Maxwell, looking steadily in the minister’s face.

‘Meaning you,’ replied the latter, continuing in the most friendly tone; ‘you have the right, it seems to me, and you ought to have the will, to unmask this intruder. It is your own fault, Maxwell, with good friends at your back, if you have not the power. Come, you may count upon me for one in this matter. To-night I have reason to believe Mistress Carmichael will again meet this mysterious personage in the Abbey garden, whilst the revel is at high tide in the palace. Follow her to the tryst, confront your rival and compel him to declare himself, or to do you reason with his sword. If needed I will be at your back, and should all other means fail, six inches of cold steel can easily square accounts between you.’

‘And your reason for thus interesting yourself in my concerns?’ demanded Maxwell, with a dry laugh. ‘Is it purely out of friendship for me, Master Randolph?’

‘Now you speak like a sensible man,’ replied the diplomatist, ‘and I answer you with the frankness you deserve. No! with all my regard for you, this interest, on my part, is not entirely for your sake. I have reason to mistrust this stranger; I have my suspicions of some dark plot, against which it is my bounden duty to be on my guard. If he be a friend, my plan will at once set matters on a proper footing, both as regards yourself and the lady of whom we speak. If an enemy, the sooner he is removed from our path the better. Have I not convinced you that our interests are identical? The day wanes; one more cup of the Cyprus, Master Maxwell, and then, first to the Palace, afterwards to the garden.’

Maxwell filled and emptied the cup of Cyprus as he was bidden: but his was a temperament on which wine took but little effect, or rather, in which it stimulated the faculties without upsetting the judgment. Even Randolph’s brain, powerful as that organ undoubtedly was, could not have been less affected by his potations than was the soldier’s.

As the pair, ostensibly dismissing the subject from their minds, talked gaily on about other matters, it would have been amusing to note the dexterity with which the diplomatist adapted his conversation to the purpose he had in view. How with a casual remark here, a covert sarcasm there, he endeavoured to stimulate the other’s jealousy and to arouse his alarm, whilst, at the same time, with many a plausible argument and choice anecdote, introduced as it were by chance, he endeavoured to establish the expediency of prompt and desperate measures on all occasions where a man had to deal with cases of mystery and intrigue.

Maxwell listened attentively, but the inscrutable repose of his countenance baffled even Randolph’s penetration, and he contented himself with vague and general replies, of which the other could make nothing. Nevertheless, he was resolved in his own mind what to do. With all his exterior of adamant, he was sufficiently vulnerable within. Bitterly hurt and offended at Mary Carmichael’s conduct, he had determined to forget her; but the old wound was only superficially healed over, and it would not bear being touched or tampered with yet. Also his attachment to that young lady had been of the purest and most unselfish order, and such an affection never fails to evoke all the latent generosity of a noble heart. His own impulse, as a gentleman, was to give his rival every fair advantage; to treat him, at least, as an open and honourable foe; to warn him that his movements were watched and his personal safety endangered; and to tell him, point blank, that he had done this for the sake of her whom they both loved. Surely such frankness would meet with the return it deserved; and then, if Mary really preferred this stranger, why, the dream was over, that was all. Any privation was better than this continual uncertainty; it was but giving her up, and the world would be before him again—something whispered that it would be a very different world, nevertheless. However, he made up his mind, and was more than usually merry with Randolph as they proceeded together towards Holyrood.
