[Chapter XXI—The S. O. S. from the “Griswold”]

Dave’s best good news. New ships for two. Bad news, it turns out. Runkle is on hand. The chums part company. S. O. S.! The “Griswold” attacked.

[Chapter XXII—Dave’s Night of Agony]

News of the toughest kind. Flashes from German guns. Dave plans his own attack. “Never again any mercy to a pirate!” “Belle!” Splash!

[Chapter XXIII—The Fight to Bring Belle Back]

Runkle helps valiantly. The still, white face. The surgeon shakes his head. “She did not suffer.” Darry refuses to wake up. Dan at his chum’s side. The fight for Belle’s life. “’Ware torpedo!”
