"What in the world for?"
"Well, because the authorities may want to find out more about us."
"But didn't we have our passports all right? And weren't our papers in proper shape?" asked Charlie indignantly.
"As far as we ourselves are concerned, yes," said Blake. "But you must remember that passports have been forged before, by Germans, and——"
"I hope they don't take us for Germans!" burst out Charlie.
"Well, we don't look like 'em, that's a fact," said Blake, with a smile. "But you must remember that the English have been stung a number of times, and they aren't taking any more chances."
"Just what do you think this fellow's game is?" asked Charlie.
"Well," answered Blake slowly, and as if considering all sides of the matter. "I think he has been detailed by the English Foreign Office, or Secret Service, or whoever has the matter in charge, to keep an eye on us and see if we are really what we claim to be. That's all. I don't see any particular harm in it; and if we objected, kicked, or made a row, it would look as if we might be guilty. So I say let it go and let that chap do all the spying he likes."
"Well, I guess you're right," assented Joe.
"Same here," came from their helper.
