"It's highly possible, Corbett," answered Connel, and glanced around. "If they have any other ships of that size, the Polaris will be able to handle them."

"Yes, sir." Tom smiled. "The repair crew did a good job on her." The cadet paused. "Do you suppose one of the Nationalists planted that bomb on her fin?"

"No doubt of it," replied Connel. "And it seems to tie in with a rather strange thing that happened in the Venusian Delegate's office the day before it happened."

"What was that, sir?" asked Tom.

"Three priority orders for seats aboard a Venusport—Atom City express were stolen. Before a check could be made, the ship had made its run and the people using the priorities were gone. They must have been the ones that bumped you off your seats."

"How do you think that ties in with the bomb on the Polaris, sir?"

"We're trying to figure that out now," said Connel. "If only we knew what they looked like it would help. The girl at the ticket office doesn't remember them and neither does the ship's stewardess."

"But we saw them, sir!" exclaimed Tom.

"You what!" roared Connel.
