In response to these words, Hal and Chester, accompanied by Major Derevaux and Colonel Fuesco, made their way from the room. In the corridor they encountered the American ambassador and Uncle John. The latter was walking back and forth nervously and muttering angrily to himself.
"Here we are, Uncle John," said Chester.
Uncle John jumped as though he had been shot, for he had not perceived their approach.
"You young rascals," he exclaimed, "so you have been released, eh?"
"Yes," said Chester quickly, "we have been released providing we can really apprehend the man who is the spy."
"What do you mean?" asked Uncle John anxiously.
Hal followed Chester's lead, for he wished no obstacle to be put in their path.
"If we can catch the spy, we shall be permitted to go free," he said,
"I see," said Uncle John. "But I can't see that spy-catching is any of your business."
"Well, we have promised to do the best we can," said Chester.
