“Now I guess we’d better make a trip to the lighthouse,” remarked Ned, the next afternoon, when the Dartaway had been put in shape. “We ought to warn Mr. Hardack.”

“And, incidentally, I suppose, Jessica,” added Bob.

“I think they’ll give the whole plan up, now they see we are after them,” Jerry added. “I believe they’ve cleared out for good.”

“It’ll do no harm to go over and see Mr. Hardack,” Ned insisted. “If we find out there’s no likelihood of the thing coming off, we needn’t say anything.”

They got to the lighthouse about five o’clock. Mr. Hardack greeted them warmly.

“Come right in,” he said. “Sorry Jessica is not home. She was just wishing some visitors would come, and about an hour ago that Nixon chap came along in his boat and took her for a ride.”

Ned seemed less happy than when the start had been made.

“But come in,” the lighthouse keeper went on. “I’ve got some fresh milk and Jessica baked some cookies this morning.”

Bob was the only one who looked pleased.
