“So we decided to go up to the city and ask Mr. McKay who it was had taken the Brownell place. Instead of Mr. McKay we found his secretary, Higginbotham, who professed to know nothing about the matter. Yet, when we arrive down here, we find Higginbotham in the radio plane, visiting a schooner well off shore.

We spent two or three hours longer in the city, which gave him the chance to beat us. Now what brought him down here?”

“Search me,” said Bob. “There may be a big liquor plot, and he may be in it. Probably, is. Perhaps he was alarmed at our inquiries and hurried down to keep things quiet for a while.” 62

“That’s just what he did, Bob, I do believe,” said Jack, approvingly. “I believe you’ve hit it.”

“Oh, well, come on,” said Bob. “Let’s have this plunge.”

“Calling for us, Sis?” said Bob. “Who is he?”

“I don’t know,” she said. “He hasn’t given his name. I believe he’s calling from New York.”
