Tom Swift and His Airline Express by Victor Appleton

Closing in on Tom, the four men soon had him securely bound with ropes. He felt there was little use in struggling against such overwhelming odds. He must conserve his strength until he could use it to better advantage. For the young inventor did not intend to remain any longer than he could help a prisoner of these four men on this lonely island. For it was a lonely island.

Though nearer that end of the lake where Shopton was located, still this little irregular circle of land, rocks, and shrubbery known as Loon Island was a lonesome place. Its name might indicate that, for in times past many loons made their nesting place on the island, and the loon is a very shy bird-it loves not human company.
