Anyway the boy was full of mischief.

The night the monk got away he had been sent to bed early because of some trick he had played.

He slept in a little room at the head of the stairs leading to the second story.

His window opened on a lean-to shed, and, as it was a warm evening, the sash was raised.

Shortly after the youngster got to bed, something slipped over the back fence, and after prowling about the yard for a moment, climbed upon the shed and through the window into the room where Mike was just in the act of falling asleep.
