Mending the rein he walked the horse home, and at the hotel found his two old friends, Mr. Mole and Harvey, whom he had left in New York, and who had just arrived.
The professor walked with a stick, being yet a little lame.
Harvey was the bearer of a long letter and many kind messages from Lena Vanhoosen.
It was a great pleasure to Jack to see his friends, to whom he related what had happened since his arrival in San Francisco.
"By all means arrest Maltravers at the theatre to-night," said Harvey, "and put a stop to his intrigues, once for all."
"I will," replied Jack.
"Suppose I come in at the end of the first act and bring a police officer with me?"
"That will do," answered Jack.
Mr. Mole had gone outside in the corridor, and all at once Jack and Harvey heard a great uproar.
They rushed out, and found the professor attacking a man with his crutch.
