“Not he. He went over for a purpose.”

“For a purpose?” echoed Herc, looking sharply at Ned.

“That’s what I said.”

“Oh, for a swim, I suppose you mean—an unofficial swim.”

“No, something quite different from that.” Ned sunk his voice. “He went overboard to pick up a bit of paper that fellow in the boat threw out.”

Had a bombshell exploded at Herc’s feet, he could not have looked more astonished.

“Your mind works quicker than mine, I guess, Ned,” he said, “just as your eyesight is quicker. I didn’t see any bit of paper, but supposing there was?”

“Well, it may mean nothing. The fellow may have a sweetheart ashore who chooses this means of sending him a message, and then again——”

“It might all have been an accident.”

“We may have a traitor on board,” resumed Ned, not paying any attention to the interruption.
