"Let us go now, father," she said. "We have done well to-night, and I am so anxious to know how much we have."

"Yes, Nan, let us be off at once," the old man wearily replied. "I am greatly confused and do not fully understand all that has taken place. You must thank the stranger for his kindness, though. His music was wonderful."

"But he has gone, father. He vanished among the crowd, and I am afraid that I shall never see him again. Oh, he was splendid! How I wish you could have seen him."

"But I heard him speak, Nan, and listened to his playing, so that was something."

They were standing close to each other, talking as simply as if they were completely alone. In her great innocence, Nan did not realise that greedy eyes were watching the bulging hat she was still holding before her, and that itching hands were but waiting an opportunity to snatch away the treasure.

They had turned to leave the place, when a policeman suddenly appeared before them.

"I have been instructed to accompany you home," he briefly informed them.

Into the girl's eyes came a look of fear which the policeman was not slow to notice.

"Don't be afraid, Miss," he remarked. "It is for your welfare that I am here. It is not safe for you to go alone through the streets with all that money. There are people watching you already to snatch it away from you."

"Are there?" and the girl looked fearfully around. "I don't see them."
