“It would help Dalton much, and be of still greater value to the wretches behind Dalton,” replied Mr. Seaton, grinding his teeth. 52

“Then, sir, as the tug went back to mainland with two of the doctors, isn’t it possible that some spy may have concluded that all the doctors had returned until summoned again?”

“That seems very likely,” nodded the owner of the bungalow.

“Then perhaps Dalton—and those behind him—hope that Mr. Clodis will become much worse, and die before you can again summon help from the mainland.”

“That looks more likely than any other explanation of these strange happenings,” agreed Mr. Seaton, studying the floor, while the frown on his face deepened.

“And the scoundrels,” quavered Tom, “may even come back during the night and try to make sure that Mr. Clodis dies without ever becoming conscious.”

“I don’t quite see why they need care so much,” replied Mr. Seaton, slowly. “Dalton got all of Clodis’s papers—the ones that I wanted preserved from the wretches back of Dalton.”

“Are you sure they have all?” propounded Captain Halstead.

“Why, Clodis carried the papers in a money-belt, and, in undressing him, we found that belt gone.” 53
