I am looking for a story from my school days. It was the tale of a warring gangs of boys and featured a character known as 'Greenbreeks". I believe it was written by Sir Walter Scott and the story appeared as a short story in a general reader. It may have been condensed from a longer work by Scott. But the fact is, I cannot locate the story anywhere and would very much appreciate if someone could help me locate this tale from so long ago.
