Miss Elting was of the opinion that they were much better off in their hiding place than at an anchorage out in the lake, always provided that their enemy did not find them out.
Harriet agreed with her, but thought they would be in a serious situation if their unknown enemy were to find them.

He had shown evidences of keenness that made the finding of the "Red Rover" appear to be a simple task for him.

That he would annoy them further, the girls were positive; that he already had located them was more than possible.
Splash! Their conversation was suddenly checked.

A stone had dropped but a few feet from the rear end of the "Red Rover," falling into the creek.
Harriet laid a finger on her lips.

Tommy had started to speak, but checked herself in time.
