“He’ll have to do his own guessing,” Dan rejoined. “I’m not going to help him solve the puzzle. But surely something must have happened to us.”
For a few minutes nothing was seen, in any quarter, of the enemy craft. At last, however, a glimpse was caught of a periscope to starboard.
“He’s trying to figure us out,” Dan chuckled. “I hope we don’t look good enough for him to waste a torpedo!”
His hand at the engine-room telegraph, Dan waited, while Ensign Stark watched that periscope through his glass.
“There goes the periscope out of sight,” announced the watch officer, presently.
A full ten minutes passed. Then sight of the periscope was picked up once more, this time closer in.
“You’ve got him guessing, at the least,” Dave smiled.
“Yes, but I’m still hoping he won’t guess ‘torpedo,’” was Dalzell’s response. “Stand by, gunners!”
“There comes the conning tower,” Stark announced.
“He’s going to gun us, then,” Dan concluded. He waited, standing almost on tiptoe, until the gray back of the sea monster thrust itself up through the water.
