"Where's Mus?" asked the boy disappointed.
"Mus is busy preparing things for your return home. She is quite worried about you."
"Poor Mus," said Harold, regretfully.
"Betty," said George in a professional tone, "you look tired. You must take a little rest yourself."
She looked up at him. His usual healthful countenance was drawn and haggard. Doubtless he had been greatly shocked with Harold.
"And you?" she returned anxiously. "I never saw you look so worn. Have you been up with a case all night?"
"Yes, a very serious one," he returned with a shadow of perplexity. He leaned over Harold fondly.
"Be a little man, sonny. I'll come for you this afternoon."
The boy nodded gravely, and Walter turned to Betty.
"Goodbye," he said.
