Somerset returned to the top of the great tower with a vague consciousness that he was going to do something up there--perhaps sketch a general plan of the structure. But he began to discern that this Stancy-Castle episode in his studies of Gothic architecture might be less useful than ornamental to him as a professional man, though it was too agreeable to be abandoned. Finding after a while that his drawing progressed but slowly, by reason of infinite joyful thoughts more allied to his nature than to his art, he relinquished rule and compass, and entered one of the two turrets opening on the roof. It was not the staircase by which he had ascended, and he proceeded to explore its lower part. Entering from the blaze of light without, and imagining the stairs to descend as usual, he became aware after a few steps that there was suddenly nothing to tread on, and found himself precipitated downwards to a distance of several feet.
Arrived at the bottom, he was conscious of the happy fact that he had not seriously hurt himself, though his leg was twisted awkwardly. Next he perceived that the stone steps had been removed from the turret, so that he had dropped into it as into a dry well; that, owing to its being walled up below, there was no door of exit on either side of him; that he was, in short, a prisoner.
Placing himself in a more comfortable position he calmly considered the best means of getting out, or of making his condition known. For a moment he tried to drag himself up by his arm, but it was a hopeless attempt, the height to the first step being far too great.
He next looked round at a lower level. Not far from his left elbow, in the concave of the outer wall, was a slit for the admission of light, and he perceived at once that through this slit alone lay his chance of communicating with the outer world. At first it seemed as if it were to be done by shouting, but when he learnt what little effect was produced by his voice in the midst of such a mass of masonry, his heart failed him for a moment. Yet, as either Paula or Miss De Stancy would probably guess his visit to the top of the tower, there was no cause for terror, if some for alarm.
He put his handkerchief through the window-slit, so that it fluttered outside, and, fixing it in its place by a large stone drawn from the loose ones around him, awaited succour as best he could. To begin this course of procedure was easy, but to abide in patience till it should produce fruit was an irksome task. As nearly as he could guess--for his watch had been stopped by the fall--it was now about four o'clock, and it would be scarcely possible for evening to approach without some eye or other noticing the white signal. So Somerset waited, his eyes lingering on the little world of objects around him, till they all became quite familiar. Spiders'-webs in plenty were there, and one in particular just before him was in full use as a snare, stretching across the arch of the window, with radiating threads as its ribs. Somerset had plenty of time, and he counted their number--fifteen. He remained so silent that the owner of this elaborate structure soon forgot the disturbance which had resulted in the breaking of his diagonal ties, and crept out from the corner to mend them. In watching the process, Somerset noticed that on the stonework behind the web sundry names and initials had been cut by explorers in years gone by. Among these antique inscriptions he observed two bright and clean ones, consisting of the words 'De Stancy' and 'W. Dare,' crossing each other at right angles. From the state of the stone they could not have been cut more than a month before this date, and, musing on the circumstance, Somerset passed the time until the sun reached the slit in that side of the tower, where, beginning by throwing in a streak of fire as narrow as a corn-stalk, it enlarged its width till the dusty nook was flooded with cheerful light. It disclosed something lying in the corner, which on examination proved to be a dry bone. Whether it was human, or had come from the castle larder in bygone times, he could not tell. One bone was not a whole skeleton, but it made him think of Ginevra of Modena, the heroine of the Mistletoe Bough, and other cribbed and confined wretches, who had fallen into such traps and been discovered after a cycle of years.
