Highway Robbery

'Hold the mare for me, lad. And when I come back I'll give you a golden guinea.'\nIt's more money than the street urchin has ever dreamt of. But who is the rider, and why is there so much interest in his big black horse? And will the boy ever see the money he has been promised?\nThere's highway robbery in the air, but it isn't always entirely clear just who is trying to rob who.
