he would accompany the boys at once. As they would have passed out, the
general's orderly once more entered the room.

"The American ambassador is without, sir," he said, "and demands an
immediate interview with you."

General Ferrari turned to Colonel Fuesco.

"You see what trouble you have brought down on my head," he said, with a
smile. "I won't bother to see the ambassador now," he said to his
orderly. "I shall send these lads to greet him."

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.
