IT WAS ABOUT DOT 16, SHIFT CHANGE TIME, THE EQUIVALENT OF four in the afternoon for third shifters. So, Markus was approaching the end of what, for any normal earthbound person, would be his workday. Of course, like almost everyone else in the Cloud Ark, he worked the whole time he was awake. Even his recreational activities—such as martial arts practice in the Circus—had a larger purpose. So the "afternoon" shift change and end of his "workday" were purely formal observances. Nevertheless, he was in the habit of using this time of day for dealing with what used to be called paperwork. And as part of that he had invited to his little private office off of the Tank the Only Lawyer in Space, Salvatore Guodian. Son of a Singaporean Chinese father and an Italian countess whose parents had gone to that city-state as tax exiles, he had been educated in a school for mostly British expats, matriculated at Berkeley, dropped out after one and a half years to join a tech startup, lost his shirt, bummed around to various other startups, finally made some money, become interested in the law, essentially bought his way into law school despite not having a bachelor’s degree, worked for fifteen years at the Los Angeles, Singapore, Sydney, Beijing, London, and Dubai offices of a white-shoe law firm, been passed over for partnership, resigned, ridden his bicycle across China, moved to San Francisco, and become the general counsel of a digital currency trading firm while in his spare time volunteering for a nonprofit cyber rights organization and going out into the desert to launch very large home-brew rockets to the edge of space. Sal, as he was universally known, had been one of the first people chosen to work on the Constitution of the Cloud Ark, and so had spent a year and a half at The Hague before getting "yanked," as the expression went, and launched up here. He was forty-seven years old but in dim light could have passed for thirty.
