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.

At last he reached the window. It was made of the small diamond-shaped
panes at that
