"Jack," called out the boatbuilder, "see if young Melville has a long, white envelope anywhere about him. In the inside coat pocket, if I remember rightly."
"Don't you dare!" challenged young Melville. But Jack glanced down at him with contempt, retorting:
"I follow only Mr. Farnum's orders. People who follow your orders take too big a risk of having to go to jail."
In Don's inner coat pocket rested a long, white envelope. Jack fished it out with a cry of triumph.
"Got it, Jack?" hailed the boatbuilder.
"Yes, sir."
"Then hold on to that envelope until we have a good chance to look it over. It's supposed to contain plans, or some sort of information, that you were supposed to be selling the Melvilles to-night."
"What?" gasped Captain Jack.
"Oh, there's a lot to the affair, and some of it needs unraveling, but we'll get to the bottom of it yet."
"I should say we'd have to!"
