"Just a minute, Mr. Carpenter," I cried as he neared the end of his peroration and was, I fancied, about to slam up the receiver. "Don't you remember me? I was at Leland with you and used to work in your laboratory in the atomic disintegration section." "What's your name?" he demanded. "Bond, Mr. Carpenter." "Oh, First Mortgage! Certainly I remember you. Mighty glad to hear your voice. How are you?" "Fine, thank you, Mr. Carpenter. I would not have ventured to call you had I not known you. I didn't mean to impose and I'll be glad to see you in the morning at nine." "Not by a long shot," he cried. "You'll come up right away. Where are you staying?" "At the El Rey." "Well, check out and come right up here. There's lots of room for you here at the plant and I'll be glad to have you. I want at least one intelligent report of this experiment and you should be able to write it. I'll look for you in an hour." "I don't want to impose--" I began; but he interrupted. "Nonsense, glad to have you. I needed someone like you badly and you have come just in the nick of time. I'll expect you in an hour." * * * * * The receiver clicked and I hastened to follow his instructions. A ringside seat was just what I was looking for. It took my taxi a little over an hour to get to the Carpenter laboratory and I chuckled when I thought of how McQuarrie's face would look when he saw my expense account. Presently we reached the edge of the grounds which surrounded the Carpenter laboratory and were stopped at the high gate I remembered so well. "Are you sure you'll get in, buddy?" asked my driver. "Certainly," I replied. "What made you ask?" "I've brought three chaps out here to-day and none of them got in," he answered with a grin. "I'm glad you're so sure, but I'll just wait around until you are inside before I drive away." I laughed and advanced to the gate. Tim, the old guard, was still there, and he remembered and welcomed me. "Me ordhers wuz t' let yez roight in, sor," he said as he greeted me. "Jist lave ye'er bag here and Oi'll have ut sint roight up." I dropped my bag and trudged up the well remembered path to the laboratory. It had been enlarged somewhat since I saw it last and, late though the hour was, there was a bustle in the air and I could see a number of men working in the building. From an area in the rear, which was lighted by huge flood lights, came the staccato tattoo of a riveter. I walked up to the front of the laboratory and entered. I knew the way to Carpenter's office and I went directly there and knocked.
