It was heavy running, and we both began to get weary. Then I caught my foot in a briar and fell. Immediately the young man rushed to the wall and began scrambling up it, but just as he was drawing his leg over the top I caught him by the heel. For a moment he struggled and kicked, then by sheer weight I brought him down at my feet, and an armful of masonry along with him. I caught him by the neck and tried to ask his name, but found we were too breathless to speak.
