That sort of thing. But Biggs came through, every time, with flying colors. And with each succeeding success, another of the grim, suspicious lines melted from around the corners of Inspector Cooper's mouth, until he was beginning to look almost like a human being. Meanwhile, Cap Hanson's face got daily ruddier, happier, and grinnier. He was just one big smile on legs as he saw his son-in-law-to-be coming closer and closer to the coveted stripes. "Just four more days, Sparks!" he chortled happily to me. And then, "Just _three_ more days! Just _two_ more--" He rubbed his hairy paws together gleefully. "Two captains in the same family! Ain't that somethin'? Boy, did you see the way he come through on that test yesterday? Cooper got Garrity to cross the heat control an' grav plates. The ship was hot an' weightless at the same time--" "So that's what it was?" I grumbled. "Hell, who's taking this test--Biggs or us guinea-pigs? I went soaring to the ceiling, boiling like a kettle--and with the gravs off, I couldn't even drip sweat!" "But Lanse fixed it!" gloried Hanson. "Spotted the trouble in three minutes flat, and had the circuits straight before you could say 'hypertensile dynamics'! What a lad!" "Two more days," I said. "All I hope is that I can live through it. If Cooper gets any more whacky ideas--" "Hrrrrumph!" came a voice from the doorway. I spun, startled. What did my mama tell me about talking in front of a person's back? It was Inspector Cooper! I said, "Look, Inspector--the acoustics are lousy in this room. Anything you heard which might have sounded like your name was strictly coincidental." He glared at me. Then at Cap Hanson. Then at me. And, boy, what I mean--that guy could really glare! "So!" he said. "_Inspector_, eh?" Oh-oh! It dawned on me, all of a sudden--but too late--that I'd upset the legumes with a vengeance. Calling him "Inspector," when, so far as I was concerned, he was an officer in the Quarantine Service. "Inspector, eh?" he repeated. And crisped Hanson's burning cheeks with a glance. "Well, Captain, it is just as I thought. Too many years of service have taken their toll on your discretion. When you start taking common radiomen into your confidence--" I did the best I could. I rallied around. "Now, wait a minute, Inspector!" I said. "Captain Hanson didn't tell me who you were. I--I guessed it. I'm pretty good at things like that. I figured it out the first time I saw you. It's my psychic--" "It will be your neck," he snarled, "if you don't shut your yap! Well--now that you know who I am, I might as well tell you why I'm here. I need your cooperation in giving Lieutenant Biggs his final test." Some of the chagrin left Hanson's eyes; his voice was hopeful. "_Final_ test?"
