Now it happened that as I gained the corridor, I saw in the dim light a figure retreating hastily before me; but with noiseless footsteps, and having in mind the strange attempt to play the spy on us, I made no doubt but that here was the culprit, and followed up. I saw the figure turn at the end of the corridor and enter another gallery, then another, and yet another, finally vanishing as it were against the wall. Owing to my not knowing the way properly, and to the semi-gloom, I was unable to follow fast enough to overtake the spy, who flitted before me like a ghost, but in a very human hurry. When at length I came up to the wall, I looked to see if there was a door of any kind; but could discern nothing, and was so astonished that for a moment I felt a little chilled, thinking that it may have been a spirit after all. Fortifying myself, however, with the thought that if it was a spirit, it seemed in no way anxious to meet me, I went to a closer examination, and saw by the moonlight that I was before a door, painted in exact imitation of the marble wall. This settled my doubts, and putting my shoulder to it, I made a trial, with all my strength, to force the passage, but in vain. I therefore gave up the matter, and turned to find my way back. This was, however, easier said than done. I could not find the gallery I wanted, and after groping about hopelessly for a little time, thought that I had best give a shout, which would no doubt summon some one to my aid. I was just about to carry this into execution, when, on further reflection, it struck me that I might be landed in other difficulties thereby, and that I might make another try to free myself, without bringing the house about my ears, and perhaps compromising the secretary, who had, I saw, an active and enterprising enemy under his own roof. So I stilled my tongue and made further exploration, with the result that I found myself before a stairway, that led to the floor below me, and determined to see where this would take me. Accordingly I descended as softly as possible, and arrived in a few steps at a small landing, covered by a carpet so thick, that I felt as if I was treading on the softest of moss. At the end of the landing, and opposite to me, was a half-opened door, the room inside being in light. Stepping noiselessly up to the door I peered in, and saw a chamber furnished with the utmost luxury, and apparently just vacated by its occupants. In a corner of the room stood a harp, lying on a table close to a low luxurious seat were some articles of dainty feminine embroidery; soft silken curtains shrouded the walls, and the ceiling was painted, apparently with some representation of the history of the house. A white marble figure of Cupid held out at arm's length a lamp, whose opal shade softened its bright light; and on a gilded triangle, set in an alcove, swung a blue and scarlet macaw--a rare Eastern bird--who, with his head tucked under his wing, slept in a position which would
