"D'you really think that power boat we saw is going out to meet a
submarine?"

"Ask me an easier one," said Morgan. "I can't guess. But she might. We

"They read all the news that passes between our ships, too, unless it is
in a secret code. And they pick everything they need to know about our
ship movements out of the air."

"Six of one and half a dozen of the other," grinned Frenchy. "You bet
our operators steal German messages."

"It's likely. You know that chap on the _Colodia_ whom we all liked so

supposed only to be picked up by German submarines.
