"We'll have dinner, and then see a stereo, and I know a nice quiet spot where we can talk—"

"Talk?" demanded a gruff voice behind Roger.

The cadet whirled to find himself staring into the grim face of Hyram Logan. "Just what would you talk about, Cadet Manning?" demanded Jane's father. Billy stood at his father's side, grinning broadly.

"Uh—er—ah—radar, sir, the—er—problems we find in radar."

Logan turned to Jane. "Are you interested in radar, Jane?"

"Not particularly, Father," said Jane, a twinkle in her eye. Tom and Astro were trying unsuccessfully to stifle their laughter.

His face suddenly flushing crimson, Roger looked around and stammered, "I—uh—I just remembered—got to see a feller about a hot rocket!" And Roger jumped off the slidewalk to disappear into the Tower building.

Laughing out loud now, Tom and Astro said good-by to Jane and her father and followed Roger.

Inside the gleaming Tower of Galileo, the two boys raced up the slidestairs and caught up with Roger.

"Well, Romeo," said Astro, slapping him on the back, "that was what I call a strategic retreat in the face of overwhelming odds."
