"Opening the door, he then stepped into a dark narrow passage, leading, as he was well aware, to the Chapel. On the left there were doors communicating with the King's Bench Ward, and the Stone Ward, two large holds on the master debtors' side. But Jack was too well versed in the geography of the place to attempt either of them. Indeed, if he had been ignorant of it, the sound of voices, which he could faintly distinguish, would have served as a caution to him. Hurrying on, his progress was soon checked by a strong door, several inches in thickness and nearly as wide as the passage. Running his hand carefully over it in search of the lock, he perceived, to his dismay, that it was fastened on the other side. After several vain attempts to burst it open, he resolved, as a last alternative, to break through the wall in the part nearest the lock. This was a much more serious task than he anticipated. The wall was of considerable thickness, and built altogether of stone; and the noise he was compelled to make in using the heavy bar, which brought sparks with every splinter he struck off, was so great, that he feared it must be heard by the prisoners on the debtors' side. Heedless, however, of the consequences, he pursued his task. Half an hour's labour, during which he was obliged more than once to pause to regain breath, sufficed to make a hole wide enough to allow a passage for his arm up to the elbow. In this way he was able to force back a ponderous bolt from its socket; and to his unspeakable delight, found that the door instantly yielded. Once more cheered by daylight, he hastened forward and entered the Chapel.
