Santley. "Come in and let me hear what you have to say, young man. What
do you know about Mr. Blake?"

"Did you know he had been out at sea on an oil tender to-day?" blurted
out Whistler. "She was chased by a submarine chaser, but the tender
escaped in the fog. Afterward she came into Rivermouth Harbor without
her cargo."

"What's this? What's this?" demanded Mr. Santley. "Why, that has nothing
to do with the factory."

They were in his private office. He stood with his hand upon Whistler's
shoulder and asked the boy sternly:

"What have you to tell me about Mr. Blake, anyway? I don't want to hear
a lot of inconsequential gossip. I am worried about the man."

"Yes, sir. So am I," declared Whistler very earnestly. "I've been
worried about him ever since the other day when we fellows were over
here trying to get some of the boys to enlist in the Navy."

"Ah, were you one of that crowd?" asked Mr. Santley.

"Yes, sir; and coming over here we saw that man Blake----"

He went on to tell the manager of the munition factory about how his
suspicions were aroused and about the water wheel he had found at the
foot of the dam, ending with a detailed account of the affair of the oil
tender.
