This peaceful, cold, unruffled well, formed the antechamber to the murderer’s passage. For on the right-hand side, not to be seen in the darkness, and the sublustrous confusion, by any common eye, was a small niche and footing-place not a yard above the water. It needed some nerve and vigour to spring from the lowest stepping-stone sideways to this scarcely visible ledge. None, of the few whose eyes were good enough to espy it, would be tempted to hazard the leap, unless they knew or suspected that the facing would yield to the foot, that it was in fact a small door purposely coloured and jointed like the slimy green of the masonry. In this well the murderer must have lurked; and he might have done so from one year’s end to another. There with the craft of his devilish race--my Uncle may admire them, but not I--and with their wonderful powers of sight, he must have found this entrance, and rejoiced in his hellish heart. As for Mrs. Daldy, she found it out at the other end, most likely. Unless my memory fails me, I spoke long ago of some boards which sounded hollow to the ring of my childish knuckles. These were in the skirting--if that be the proper name for it--under the centre of the great oriel window. The oak slides, when pressed from below, ran in a groove with but little noise, and without much force being used: but it required some strength to move them on the side of the corridor. It was the sound of these sliding boards which had first drawn Judy’s notice: but as they were in deep shadow, I neither perceived the opening, nor gave him the opportunity. That woman would never have dreamed of the thing, if she had not surprised me one day when I was prying about there; she must have returned alone, and being, as we have seen, a superior cabinet-maker, discovered the secret which baffled me. As I did not want Judy to catch cold by watching there any longer, I had this horrible passage walled up at either end, and built across in the middle. Having thus made good my arrears, I am at liberty to proceed. When my Uncle had paused from his many sorrows, which he did with a mellow dignity not yet understood by me; and when I, in the fervour of youth, had offered much comfort kindly received, but far better let alone, I asked him for one thing only:--the most minute and accurate description he could give of that Lepardo Della Croce. His answer was as follows:--
