I knew that I hadn't a care in the system worth worrying about. I knew that it didn't matter the least bit whether or not I got those figures co-ordinated for Mr. Ames. If he fired me for not doing them, so what? Wasn't I going to marry his daughter—Margie Amelita Ames? You can bet your last rocket charge I was, and if he or that fat, snooty, dictatorial wife of his objected, I'd just tell them to—

O'Graeme with the bulging green eyes, picked up the vial and carefully replaced the stopper. He was smiling. He started to say, "Well, what do you—"

I stood up, and leaned forward across the desk. "Slane, ol' bosom pal of mine," I said, "You've got something there. Listen, why let a stuffed shirt like Fleming Ames in on it? I'll handle it for you. I'll make us millions."

Slane O'Graeme looked at me and frowned a little. "Ummm," he said skeptically. "I'm sure you mean well, Mr. Dineen, but hadn't you better wait until you get over feeling—"

"Feeling what?" I demanded. "I assure you, palsy, that I'm not in the slightest upset—"

"Have you a laboratory, like Mr. Ames'? Can you synthesize—"

I waved a hand airily. "Laboratory? Don't need one for something simple as that. I studied chemistry in high school, and I assure you, pal, that I can quite easily—"

O'Graeme shook his head slowly. "I've tried this stuff often, Mr. Dineen, and I'm used to it, but I see that you—Perhaps I'd better come back tomorrow evening instead of—"

"And lose a whole day?" I scoffed. "Why, we'll be rich by then. Come on, palsy. Let's go back and join Fleming Ames' dinner party. I want you to meet Margie Ames. The old folks don't know it yet, but Margie and I are engaged. Besides," I added with a sly grin, winking at him, "there is a tank full of mermaids back there that'll knock your eyes out. It cost a fortune to have them brought in from Mercury."

I took O'Graeme by the arm and propelled him out into the long corridor. The Polaroid glass walls of the huge building looked down upon the great City of Mars with its network of shuttle-car tubes, the 'copter landings and—We passed a section of wall that opened onto the sky parkway and a draft of cold fresh air hit me. I stopped suddenly.
