“Why, I didn’t know anyone lived there,” Dan said in surprise.

“A family of four moved in about three weeks ago,” Mr. Holloway revealed. “They’re living in a shack there—the mother and father and two youngsters.”

“Rabb Island is low,” the Cub leader said. “And the river has risen several feet in the last few hours.”

“The Dustin family has a boat of sorts,” Mr. Holloway said. “I wouldn’t worry, only I know Mr. Dustin went away late this afternoon just before the storm broke. Whether he got back or not, I don’t know.”

“Then Mrs. Dustin and the two children might be on the island alone?” Mr. Holloway asked.

“That’s what’s worrying me. I don’t know.”

“Any way we can find out?”

“I intend to row over there as soon as I get things cleaned up here. But the water’s risen so fast I haven’t had a chance.”

“I’ll go over right away and check up,” volunteered the Cub leader. “That is, if I can borrow the boat.”

“Midge and I hauled it up by the boat house. The dock is under water now.”
