"Acquainted with every part of the gaol, Jack well knew that his only chance of effecting an escape must be by the roof. To reach it would be a most difficult undertaking. Still it was possible, and the difficulty was only a fresh incitement. The mere enumeration of the obstacles which existed would have deterred any spirit less daring than Sheppard's from even hazarding the attempt. Independently of other risks, and the chance of breaking his neck in the descent, he was aware that to reach the leads he should have to break open six of the strongest doors of the prison. Armed, however, with the implement he had so fortunately obtained, he did not despair of success. 'My name will not only be remembered as that of a robber,' he mused, 'but it shall be remembered as that of a bold one; and this night's achievement, if it does nothing else, shall prevent me from being classed with the common herd of depredators.' Roused by this reflection, he grasped the iron bar, which, when he sat down, he had laid upon his knees, and stepped quickly across the room. In doing so, he had to clamber up the immense heap of bricks and rubbish which now littered the floor, amounting almost to a cart-load, and reaching up nearly to the chimney-piece; and having once more got into the chimney, he climbed to a level with the ward above, and recommenced operations as vigorously as before. He was now aided with a powerful implement, with which he soon contrived to make a hole in the wall. "The ward which Jack was endeavouring to break was called the Red-room from the circumstance of its walls having once been painted in that colour: all traces of which, however, had long since disappeared. Like the Castle, which it resembled in all respects, except that it was destitute even of a barrack bedstead, the Red-room was reserved for state prisoners, and had not been occupied since the year 1716, when the gaol was crowded by the Preston rebels. Having made a hole in the wall sufficiently large to pass through, Jack first tossed the bar into the room and then crept after it. As soon as he had gained his feet, he glanced round the bare black walls of the cell, and, oppressed by the misty close atmosphere, exclaimed, 'I will let a little fresh air into this dungeon: they say it has not been opened for eight years, but I won't be eight minutes in getting out.' In stepping across the room, some sharp point in the floor pierced his foot, and stooping to examine it, he found that the wound had been inflicted by a long rusty nail, which projected from the boards. Totally disregarding the pain, he picked up the nail, and reserved it for future use. Nor was he long in making it available. On examining the door, he found it secured by a large rusty lock, which he endeavoured to pick with the nail he had just acquired: but all his efforts proving ineffectual, he removed the plate that covered it with the bar, and with his fingers contrived to draw back the bolt.
