In a hundred years, so the instructors—brisk females all—had told O'Rielly in pre-flight school, no control had ever been known to slip. But one room. Nobody had passed through. O'Rielly knew it. Callahan knew it. By now the Old Woman herself, Captain Millicent Hatwoody, had probably Well, ma'am, O'Rielly searched every cranny where even a three-tailed naturally you couldn't hear me walk out while your back was turned resetting the control." "You're so thoughtful. And do you have bathing facilities?" "That door right there. Oh, let me open it for you!" Callahan said something through his teeth, then studied O'Rielly O'Rielly stood considering his shower door.

The dear little stowaway lovely neck and his own forever. O'Rielly's shower door, however, opened abruptly. O'Rielly had not opened it. O'Rielly, however, suffered a cruel stab of dismay. Surely his dear stowaway had been listening through the door. Why didn't she have brains enough to stay hid until Callahan was gone! At sight of her, of course, Callahan's eyes near popped from his old head. "Berta!" "Oh, I'm Trillium," she assured Callahan sweetly. "But Grandmamma's name is Berta and people say I'm just like she was a hundred and twenty-five years ago." "Hah? What?" Callahan blinked like his brain had been taken apart and pirate, couldn't you hide her somewheres better than that? Shut up, you don't have to explain to me, but God help the whole universe if we don't flimflam the Old Woman!" With which ominous remark, rendered in a zesty devil-may-care manner, however, Callahan threw himself into O'Rielly's shower. O'Rielly stood looking thoughtfully at lovely, womanly, exquisite Trillium. Just like that, O'Rielly felt as sparkling of mind as a spiral nebula. "My locker!" he crowed with inspiration and yanked open the doors under his bunk. He glimpsed a black ditty bag, also the cap and coverall uniform of a baggage boy. Trillium explained. "I knew the burner room would be warm." Trillium—with her shape—passing as a boy hustling bags through this ship. O'Rielly chortled as he tucked her under his bunk. "Now don't you worry about another thing!" "Oh, I'm not," she assured him happily. "Everything is going just the O'Rielly's shower opened and Callahan, glowing like a young bucko, She was fit to put frost on a hydrogen burner. "Mr. Callahan, I asked Wasn't too bad a fib. The more O'Rielly thought of Trillium, the more freeze O'Rielly's brain, then she gave Callahan the look. "I sent you "Stay at attention!" Old Woman sniffed the air near Callahan's face, The shower units were equipped so no Burnerman need be more than two steps from his responsibility. To keep the Old Woman from possibly blowing her gaskets completely, O'Rielly simply stepped in, shut the door, flipped a switch and tingled as he was electronically cleansed of person and clothes. By time he finished, the Old Woman and His onto her own words. "Facilities of the Captain's quarters are more satisfactory." happy forever. A fine loud "thump," however, was now heard. Old Woman whirled back and yanked open the doors under O'Rielly's bunk. "Of all the sappy hiding places!" Callahan yelped, in surprise of "Trillium?" His Excellency bellowed as if stung by one of the sabre-tailed hornets of his native planet. "Trillium!" at that grisly remark, the Old Woman spoke through her teeth at O'Rielly, Callahan and Trillium. "All right, come along!" looked: ready to wrap his arms around Trillium's brave loveliness and Old Woman sighed through her teeth. "Venus woman aboard this ship. Stowaway. Rattle that around your belfries."

Madame President's shapely finger now rested full on the button that could launch the fleets of war rockets that had been pre-aimed for a "Take your finger off that trigger, boy!" a heavenly voice similar to Trillium's advised from the Venus panel. Whereupon Grandpapa glared to one side. "Berta! What are you doing here? I am deciding matters of the gravest interplanetary nature!" "Impossible! The men run Venus! Nobody's turning this planet into another Earth where a man can't even sneeze unless some woman says so!" "Take him away, girls," Berta ordered coolly, whereupon her spouse was yanked from view. His bellows, however, could be heard yet. "Unhand me, you fool creatures! Guards! Guards!" "Save your breath," Berta advised him. "And while you're in the cooler, Yes, ma'am, O'Rielly sure felt like proof of something all of a sudden. away from Trillium and took a look at Callahan. Old guy looked away over Dimmy's credentials." "The Ambassadorial Suite, too," Madame President of Earth said graciously. "Anything else now, Berta?" Dimdooly off somewhere and the Old Woman eyed O'Rielly and Callahan. Especially she eyed Callahan, like running chilled drills through his "Oh, well," O'Rielly muttered, once he and Callahan were safely beyond did Trillium's Grandmamma let him go?"
