CHAPTER IX--THREATS TO A PRISONER 103 What the Danes "got." The chorus of terror. The ober-lieutenant talks. The inquisition. Talk of courtesy. Dave turns stiff. "Where have I heard that name before?" "Things will go badly with you when you arrive in Germany!" CHAPTER X--LIKE THE FRENCH AND ENGLISH 109 Captain Kennor is polite. A look-in at the periscope. "Yankee meat." Dave is tricky. Shots and a threatened ramming. "You idiot!" Dave plays for his own finish. CHAPTER XI--A VICTIM OF COURTESY 115 What of the woman? Mrs. Launce speaks for herself. The game of cross-bluff. An invitation bluntly refused. The turn of the prisoners. On the surface. "You are eager for death." The mystery of the Launces. "You are the Countess of Denby!" "Save your denials for use before a German court." Dave invited on deck. "You are a good boaster." Something to interest him. CHAPTER XII--GERMAN BRUTALITY AT ITS WORST 126 Radio direct to Germany. Could any woman love this fellow? Dave expresses thanks to the enemy. "My card." The same as confession. "A pleasant evening for four!" The wild brutes of the sea. CHAPTER XIII--FACING THE PLANNED DEATH 135 The dropping platform. Adrift! Captain Kennor, sea scout. A splendid inspiration. A bully for safety. The tantalizing craft. A glow-worm of the waves. And then--! Like a dream. A bad report. CHAPTER XIV--DAVE PLEDGES HIS WORD FOR RESULTS 146 Just hospital. A treat for Dave's eyes. Days of bliss. "You little patriot!" Back to duty. "The Germans are beating us." The council of war. Dave's campaign map. Planning the Big Hunt. Something new--results. CHAPTER XV--DARRIN SUSPECTS THE GERMAN PLAN 155 Sweeping as a fine art. Nosing out the unseen. The "Grigsby" nearly blown out of the water. A wild Yankee cheer. Touching off a nest of "sea eggs." The job of the divers. The double find. Guessing the mine-layers' trick. The "Reed" starts something. CHAPTER XVI--HITTING CLOSE TO THE SALT TRAIL 164 The non-fighting Huns. A tame capture. Not so tame! What the search showed. "Spot the stupid ones." Questioning Herr Dull-wit. The trap that worked. German bad language. CHAPTER XVII--TRYING OUT THE BIG, NEW PLAN 173 The admiral approves. Off for the real thing. Stirring up a tidal wave. Knowing how to get the thrills out of life. Trying to run up the score. The traveller in the haze. A ship of mystery and shots.
