"Commander!" Strong's voice sounded relieved. "Did you get that emergency from the Lady Venus—the S O S?"

"Yes, we did, Steve," said the commander. "How far away from her are you?"

Without a word, Tom handed Strong the position that Roger had computed. Strong relayed the information to the commander.

"If you're that close, go to her aid in the Polaris. You're nearer than any Solar Guard patrol ship and you can do just as much."

"Right, sir," replied Steve. "I'll report as soon as I get any news. End transmission!"

"Spaceman's luck, end transmission!" said the commander.

"Have you got a course for us, Roger?" asked Strong.

"Yes, sir!"

"Then let's get out of here. I have a feeling there's something more than just the usual emergency attached to that S O S from the Lady Venus."

In twenty seconds the mighty cruiser was blasting through space to the aid of the stricken passenger ship.
