"There is, so far as I am aware, no one in the house, sir, beyond these gentlemen and my domestics."

"It is a lie!" the officer exclaimed, furiously. "A man was seen to enter this house, an hour and a half ago, and no one has left since."

"A young man! Oh, I suppose you mean the young fellow who brought me a message from my cousin, at Waterford, and who called to ask if I had yet found him any employment. Oh yes, he has been here, but left some time ago, unless he is chatting with the maids in the kitchen."

The officer directed a rigorous search to be made of the house. The soldiers soon reported that every nook and corner had been examined, but that no one was to be found. At this moment, a shot was fired in the street, and a sergeant ran in.

"Captain Peters bid me say, sir, that they have just caught sight of a man on the roof of a house, some distance along the street."

"Take the prisoners to the castle, under a strong guard, sergeant. You will be answerable for their safety," the officer exclaimed, as he ran downstairs.

Directly the trap closed behind him, Walter--sure that some minutes would pass before the method of his escape was known--tore the blankets he had brought with him into wide strips, tied the ends together, and twisted them up into the form of a rope; then, coiling this over his arm, he made his way along the roofs. The street below was now a mass of people. The report that a Popish plot had been discovered, and that a number of important arrests had been made, spread quickly, as the soldiers were seen gathered round the house. The news was sufficient to stir up party feelings, and the mob which collected soon set up the shout which had, of late, been so often raised in the streets of Dublin--"Down with the Papists!"

Soon the crashing of glass was heard, as stones were hurled at the dwellings of known Catholics. Walter, anxious for the safety of Larry, who was, he knew, somewhere without, tried to look down into the street to see what was going on, believing that in the darkness he could not be seen. The flash of a musket, and the whistle of a ball close to him, showed him that his figure had been seen against the skyline.

Drawing back, he paused a moment in thought. The trapdoor would be discovered at once, and a search on the roof commenced, and the soldiers would be placed behind the houses. There was no time to be lost in continuing his search for a house with a building projecting behind, onto which he could lower himself with his rope, which was not nearly long enough to reach the ground.

Looking over at the back, between two of the sharp ridges of the roofs, he hung his rope so that it would fall across a window, fastened the end round a stack of chimneys, and then, taking hold of it, swung himself over. He had been very careful in tying the knots, and had tested them by pulling at them with all his strength; but he did not feel at all certain that they might not draw with his weight, in which case he must have been dashed to pieces on the ground far below him; but there was no time to hesitate, and, as fast as he could, he began to slide down the rope, the frequent knots affording good hold for his hands.
