interrupt them.

Then he remembered suddenly that he had no right to interfere; that it
was no affair of his with whom Isobel chose to kiss roses in a garden,
and that he was doing a mean thing in spying upon her. So he halted
behind another bush, but not without noise. His handsome young face
was thrust forward, and on it were written grief, surprise and shame.
The moonlight caught it, but nothing else of him. Isobel looked up and
saw.

He knew that she had seen and turning, slipped away into the darkness
back to the gate. As he went he heard the knight called Lord Charles,
exclaim:

"What's the matter with you?" and Isobel answer, "Nothing. I have seen
a ghost, that's all. It's this horrible dress!"

He glanced back and saw her rise, snatch the rose from the knight's
hand, throw it down and stamp upon it. Then he saw and heard no more
for he was through the gate and running down the square. At its end,
as he turned into some street, he was surprised to hear a gruff voice
calling to him to stop. On looking up he saw that it came from his
enemy, the hansom-cab man, who was apparently keeping a lookout on the
square from his lofty perch.

"Hi! young sir," he said, "I've been watching for you and thinking of
wot you said to me. You gave me half a quid, you did. Jump in and I'll
drive you wherever you want to go, for my fare was only a bob."

"I have no more money," replied Godfrey, "for you kept the change."
