It was on my return from this that, as I approached him, I saw, with some surprise, that he was in earnest conversation with a woman, and as I came nearer and he shifted his position slightly, I saw that the woman was none other than that ignis fatuus the brunette. Her back was toward me, and she was squarely facing him, so that, as I came nearer and directly toward them, I caught his eye, and, nodding with a gesture which I think he understood, I turned away and watched the manœuvres of 'the little mystery,' as Brainerd so often called the brunette, wondering if this unknown guard was also to be enmeshed in the plot she seemed to be weaving. And then there flashed into my mind that first meeting with the guard, and his avowed acquaintance with Miss Jenrys. Was this interview in any way connected with or concerning her?

The brunette had not seen me; of that I was quite assured, and even so I had small fear of recognition, for while I had not, on the occasion of our two meetings face to face, worn any disguise, I was confident that the widely different garments worn on the two occasions, together with my ability to elongate, twist, and change my features, and to alter the pitch of my voice, was masquerade sufficient. But I did not desire to become known to this anomalous personage, and I lingered here and there, within sight and at a safe distance, until I saw her nod airily and trip away, flinging a smile over her shoulder.

In the time spent in waiting the end of this little dialogue I had decided that I must know this young man—so reticent, yet so frank—better, and that I must win his confidence, and to do this perfect frankness, I knew, would be my best aid.

When the 'mystery' was safely out of sight, and on this occasion I had no desire to follow her, I rejoined the guard, and I was sure that I surprised upon his face a look of perplexity and annoyance, which vanished when I put my hand upon his arm, and, falling into step with him, began:

'I hope you understood my meaning when I went into ambush so suddenly? I really did not care to encounter your friend.'

'That is hardly the right name, seeing that the lady is a stranger to me,' he replied, slightly smiling.

'Indeed!' I retorted. 'Then may I wager that I know what she had to say to you?' I saw him flush, and his lips compress themselves as if to hold back some hasty speech, but I went lightly on: 'That is the young person who claimed the bag belonging to your acquaintance—you remember the circumstance—and if she is still as angry at me as she was on that day she was doubtless imploring you to "run me in," and put me in more irons than Christopher Columbus ever wore. Honestly now, am I not right?'

He was silent and seemed perplexed again, and I promptly changed my tone. 'If I am mistaken, and if the young woman is someone you know, I beg your pardon; but, remembering how she turned her look upon you on the occasion of that first meeting——'

'One moment,' he broke in. 'It is possible that we have been unjust in this case, and I think I may tell you, without a breach of confidence, what this young lady'—I thought he emphasized the 'lady' somewhat—'who by-the-by is a stranger to me, had to say just now.'

I bowed my assent, lest speech might cause a discussion, and he went on:
