"Can you rescue us?" Nat held his breath.
"The Moon men are on guard."
"They have no ray-guns and you have."
"The penalty would be terrible. I should be thrown to the monsters."
"Can you get us each a ray-gun? Will you risk it, to get back to Earth?" asked Nat.
A pause. Then, "My friend, I am coming."
Nat heard Benson hissing in his ear, "If we can surprise them, we can get possession of the black ship and return."
"We must get Madge Dawes."
"And smash the mirror," put in Brent.
After that there was nothing to do but wait.
