... about 800 miles in diameter. Ariel and Titania are about 1,000 and 600 respectively, and Umbriel is the baby at about 400 miles. Much of Terra's uranium was brought in from Titania back in the days of U-235 bombs and so forth. They are abandoned now." "Gentlemen," said Hartnett, facing the others seriously. "There are ten Martian cruisers and a superdreadnaught in the vicinity of Oberon and Ariel ... you may have guessed by this time that our mysterious Station 9 is on Oberon. My orders are to rescue the three technicians and destroy their samples of Isotope X-R, which is, I understand, a very unstable Isotope of plutonium. "If we could ... in some way ... destroy the bulk of the Cat strength in the Uranus system, it would be a great step forward toward the successful conclusion of this war that is still young enough to have killed relatively few people." Scott looked around at his officers and read plain astonishment on their faces. To talk of destroying such a Martian fleet with four tiny ships was madness! "The rescue of the Station personnel will be handled by Mr. Blake and the skeeter-boat. And ... if the plan I have works out properly, the destruction of the enemy fleet will be handled by ... one ship alone." He looked around the table with the vaguest suggestion of a grin on his leathery face. He nodded his head at Scott. "You're quite right, Mr. Scott, the Artemis." Scott paced furiously up and down the steel deck of the dark Control. Chavez sat before the panels, his saturnine face wreathed in demon-like curls of blue smoke from the short, black, Mexican cheroot he smoked so lovingly. "You should have heard him!" exclaimed Scott, "Standing there and calmly telling us that we are going to destroy the Cat fleet with the Artemis! Booby trap 'em, he says! Chav, I tell you he's gone looney!" Chavez shrugged and smoothed his hairline moustache. "Quien sabe?" "What the hell do you mean 'Quien sabe!' Are you trying to tell me you're thinking he can do it?" The Latin smiled, showing animal white teeth. "I understand he's done a lot of things that people said weren't possible. Personally, I should be very glad if he did what he says so we could all get back to Ley City. Amigo, I have a little friend back on Luna that is." He smiled dreamily and kissed his fingertips. "I think you're all going crazy. It's just having that man aboard."
