On the prowl at sea. Dan takes the rest cure. Dave springs a new trap for submarines. The enemy’s alarm clock. “Searchlight men, stand ready!” A shell-made geyser. The sea duel. A submarine finish. “Wasted humanity.” Orders by wireless. Shore leave. Mr. Matthews of Chicago. With the British sea-dog.
[Chapter II—The Meeting with a Pirate]
Dan has forebodings. “’Ware torpedo!” Dan’s “forty winks” end. “All hands to abandon ship!” How the trick worked. A wonderful job. The loiterer at the radio room door. “I’ll keep my eye on you.”
[Chapter III—Quick “Doings” over the Shoal]
Fisherman’s Shoal. The bubble trail. “Over with the ‘buoy’!” The driver’s job. “Come up, or take a bomb!” Talking with the Pirate. A face seen before. Bechtold does some German lying. Poison vapors. Mystery in a berth. Bechtold’s grab.
[Chapter IV—The Trail to Strange News]
Fortune is partial to the bold. A hot burn with acid. Saving words from a wreck. Use for a prize crew. Bechtold bluffs. Dave unfolds the coming fate of the prisoner. That ugly word, “spy.” “War breeds savage ideas.”
[Chapter V—Dave Talks out in Council]
The sheet that Dave saved. The drive against the troopships. “Sixty submarines!” Dave has the floor at naval headquarters. “I will stake my soul!” “Darrin, I wish we had you in our navy!” Three big cheers. Danny Grin feels proud.
