MCANDREW AND THE LAW
Charles Sheffield
Scientist and dreamer Arthur Morton McAndrew was one of my favorite science fiction
characters. He was one of Charles Sheffield's, too. In his introduction to The Compleat
McAndrew (made incomplete by this story, by the way), Charles referred to him as an
alter ego. Charles loved speculating about how far science would go, and his nonfiction
volume Borderlands of Science is invaluable for any science fiction reader. For the
McAndrew series he always included an afterword telling the reader just where the known
science in each story stopped and the speculation began. Charles Sheffield died last year,
soon after completing this story and before such an afterword could be written. Science
fiction will be the less for his passing.
It's widely accepted that there's no such thing as a free lunch. I suppose anyone with a brain in her head
would realize this applies equally well to dinner, but some people never learn; so there I was, sitting
across the table from Professor Limperis and fully expecting him to pick up the tab.
He's a wily old bird who puts a high value on his time, a fact which I've known for as many years as I've
been visiting the Penrose Institute. And today we were far from there. I was on vacation, ready to follow
the progress of the Grand Solo Solar Contest out in the Belt. What were the chances that Limperis had
traveled several hundred million kilometers for the doubtful privilege of taking me to dinner?
At the moment he was busy telling me that it was hard times for the Institute, with research budgets
squeezed tighter and tighter. I nodded sympathetically, but to be honest my mind was otherwise
engaged. I like to gamble on the outcome of the Grand Solo Solar Contest, and a prime entry for the
GSSC had just entered the dining room. I guessed that he massed between five and six hundred kilos.
In the GSSC, fat is good because the contest is just what the name suggests. You do the Belt-Jupiter-
Mars run alone, with no assistance. "No assistance" means no fuel, no food, no water. Also, no ship.
You are provided a suit with an oxygen supply and built-in fusion and chemical drives. Solo means solo.
The materials to power the drives have to come from the competitor's own body.
That's where judgment enters the picture. The chemical and fusion drives are lipid based, and a
competitor draws reaction mass only from his or her own body fat. That's why the hard-to-say "Grand
Solo Solar Contest" is better known as Fat Man's Run.
With some people, the will to win inevitably takes over. In a pinch, the drives run at reduced power on
muscle and sinew. I have seen a competitor, what was left of him, dragged out of the race by the
marshals when his total body mass was down to sixty pounds. He might recover, after a fashion, but he
would never race again. He would also never walk, run, or have sex, even in low-gee. When I saw him,
skin hung off his spongy skeleton like rags on a frame of twigs. And still he was complaining about
being removed from the race.
I became aware that Professor Limperis's eye was on me. He knew I had been distracted by my potential
