"I am not so sure, after all, that those men were Spaniards," said Harry, as he turned eagerly to the window again.
"Why?"
"Did you hear those signals?"
"I heard a bird."
"I don't think it was a bird."
"Listen; if they were birds we shall hear them again."
The boys listened patiently for several minutes, but the sound was not repeated.
"I believe they were signals, and—look—look! Isn't that Captain Dynamite himself coming out of the shadow further up the street?"
"It certainly looks like him," gasped Bert, "but who is that with him and how does he dare to walk openly in the streets?"
"It's the Spanish interpreter," whispered Harry, after a minute's inspection; "and—and Captain Dynamite, sure. Hooray."
