CHAPTER XVIII--STRIKING A REAL SURPRISE 183 "Leave the steamship to me." The shot across the bow. A shooting game for two. "You're dealing with the United States Navy!" Darrin proves himself. Irons for three. The summons that worked. A tough lot to handle. Juno of the Cabin. A deadly one, too. CHAPTER XIX--THE GOOD WORK GOES ON 192 Dave takes a chance. So does Juno. The all-right cargo. Who can the woman be? Dalzell has a fine report. Story of the sub-hold. Mother and daughter no longer mysteries. "The best in a six-month!" CHAPTER XX--DARRIN TURNS THE TABLES 204 Weather the ship master dreads. "Look at that!" Getting the drop on Fritz. Old acquaintances. Dave is angry. The German whine. Not man enough to play the game. "Why do you hate us Germans so?" Ever at Fate's orders. CHAPTER XXI--ON A MISSION OF GREAT TRUST 215 The sport of kings. "Don't shoot!" begs Danny Grin. The dull wait and the sharp dash. Out to meet the hospital ship. "One of the passengers is Mrs. Darrin." "A special interest." CHAPTER XXII--THE RED CROSS TRAGEDY 222 The Navy and family matters. Under treble lookout. Sighted. Big pay for a periscope. A wail of anguish. The race of rescue. S. O. S. The sight of Belle. Crowded decks. Two compartments smashed in. "No use, sir." CHAPTER XXIII--A NOBLE FIGHT WITHOUT WEAPONS 230 Marine patchwork. Not enough rescue to go around. "Those Red Cross women ought to be saved." But they decline. Dave approves. An answer to S. O. S. The fight to survive. The nurses admit defeat. The lurking peril. CHAPTER XXIV--CONCLUSION 244 DAVE DARRIN AFTER THE MINE LAYERS CHAPTER I WEIGHING ANCHOR FOR THE GREAT CRUISE "IT sounds like the greatest cruise ever!" declared Danny Grin, enthusiastically, as he rose and began to pace the narrow limits of the chart-room of the destroyer commanded by his chum, Lieutenant-Commander Dave Darrin. "It is undoubtedly the most dangerous work we've ever undertaken," Darrin observed thoughtfully. "All the better!" answered Dan lightly. "In our drive against the submarines off the Irish coast," Dave continued, "we met perils enough to satisfy the average salt water man. But this----" "Is going to prove the very essence and joy of real fighting work at sea!" Dan interposed. "Oh, you old fire-eater!" laughed Darrin. "Not a bit of a fire-eater," declared Dalzell with dignity. "I'm a business man, Davy. Our business, just now, is to win the war by killing Germans, and I've embarked upon that career with all the enthusiasm that goes with it. That's all."
