Here's just a sample of action from THE ROCKET'S SHADOW:
They heard the sound of footsteps on the stairs. Soon three men walked into the room. Rick felt dampness spring out on his forehead.
One of the thugs was saying "How do we know this guy on the island ain't givin' us the old double cross?"
"Don't be stupid!" the bearded man said irritably. "Without us, what good does the tube do him?"
Rick knew that the "him" the men were talking about was the Spindrift Island traitor, and he hoped that they would mention his name.
"Kogan," the bearded man continued, "we must continue work on the rocket. Get your tools."
The two boys tensed. They were hiding behind the rocket and the men were going to work on it.
Scotty nudged him. "Well, get ready," he said softly.
