I'd had a lot of cooperation getting that far. An Earth patrol had slipped down onto the Red Desert of Mars and picked up the Killicut Emeralds from where Pard Hoskins had cached them; and safe out in space again, we had pored over that string of green headlights practically slobbering. But the Big Sneer of the S.S.C., the fellow that had got me into this caper, was right there to take the joy out of it all and to remind me that this was public service, strictly. "These--" he had proclaimed with a disdainful flourish, like a placer miner pointing to a batch of fool's gold--"These jewels are as nothing, Ritter, compared with the value of the secret you are to buy with them. And be assured that if you're man enough to effect the trade--" He paused, his long nose twitching cynically--"IF you succeed, your reward will be triple what you could get for them in any market. Added to which, IF you succeed, you will be a free man." That twitch of the nose riled me no little. "I ain't failed yet!" I snarled at him. "Just you wait till I do, feller!" I slipped the string of emeralds back into its little safe. "Instead of sniping at me, why don't you get that brain busy and set our rendezvous?" With that we got down to business and fixed a meeting point out on Jupiter's farthest moon; then they took me in to the edge of Jupiter's ice-cloud and turned me loose in a peanut of a space boat with old Jupe looming ahead bigger than all outdoors and the Red Spot dead ahead. I patted my pretty enameled suit, which was a study in paris green and passionate purple. I patted the three hundred pounds of arsenic crystals for Akroida and anyone else I might have to bribe. I anxiously examined my suit's air and water containers and the heating unit that would keep them in their proper state. I had already gone over the space boat. Yeah, I was as nervous as a cat with new kittens. Feeling again for my little bottle of horrid stench, I breathed a prayer to the god of idiots and spacemen, and headed in. The big ship was long gone, and I felt like a mighty small and naked microbe diving into the Pacific Ocean. That famous Red Spot was that big, too. It kept expanding until the whole universe was a fierce, raw luminous red. Out beyond it at first there had been fringes of snow-white frozen ammonia, but now it was all dyed redder than Mars. Then I took the plunge right into it. Surprise! The stuff was plants! Plants as big as meadows, bright red, floating around in those clouds of frozen ammonia like seaweed! Then I noticed that the ammonia around them wasn't frozen any more and peeked at the outside thermometer I couldn't believe it. It was above zero. Then I forgot about the temperature because it dawned on me that I was lost. I couldn't see a thing but drifting ammonia fog and those tangles of red floating plants like little islands all around. Cutting down the motor, I eased along.
