first because there was no telling how long that anomaly might last. He also might have to take several readings over the course of the day. Heâd just finished his proposed priority listing when Sung appeared and settled himself before the main console. âThe list is up,â Roget said. âGood.â After a moment, Sung turned in his swivel. âYouâve got the Virgin first. Thatâs right. But you need to move your first observation farther north, out east beyond the Green Springs tram terminal.â Sung called up a map on the console and motioned for Roget to join him. Roget did. A red triangle appearedâa good klick to the east of the station. âThere,â announced Sung. âDonât forget to check to make sure nothingâs coming down the Mill Creek wash, either. A reading there will determine whether itâs natural, or whether itâs coming from a source in town.â Roget thought about the long walk ahead. âOh ⦠you can sign out a bicycle if you donât want to walk it.â Sung grinned. âI donât believe you mentioned that.â âSupply keeps one for us, down on the lower level. They fold and fit in the carriers at the rear of the tram cars.â âThank you. I could use it today.â Sung smiled. âI thought you might. Youâll need three locations on the river and three different intervals at least an hour apart.â Roget had planned on that. He just nodded. âIâd better get going.â Sung returned his attention to the console, and Roget finished loading the data into his duty monitor. Then he left the office and took the ramp at the end of the corridor down to the lower level. He had to walk the entire length of the corridor on the lower level to reach the supply officeâa small cubicle with a door behind it, presumably to a storeroom. The supply clerk was a black-eyed and black-haired woman. She looked up with a cautious smile. âYes?â âKeir Roget. Iâm the new E&W monitor.â âCaron Fueng.â âMonitor Sung said that there might be a bike I can sign out?â âThere is.â The clerk smiled. âSung must like you.â âOh?â âHe didnât tell Merytt about the bike for close to a month. Iâll get it for you.â Roget laughed. But as he waited for Fueng to return with the bike, he wondered if the head monitor suspected what he really was. The bike that Fueng wheeled out was the compact type with wide balloon tires. Not the speediest on paved surfaces, but much better on trails and lanes or unpaved surfaces. âJust a thumbprint, please.â She gestured to the authenticator on the corner of her desk. âI checked the tires. Theyâre fine.â Roget thumbed the authenticator panel. âThank you.â âIf you donât bring it back before five, youâll have to keep it in your office. You canât take it home.â She shrugged. âThat doesnât matter to me, but accounting doesnât like it. Rules.â She shook her head. âI appreciate the warning. I should have it back by then.â He offered a smile as he took the bike from her. He wheeled it up the front ramp and managed to get it through the security gate and the front doors without banging anything. Once outside the FSS, he rode down to the tram station. The morning was already warm and clear, more like late summer than late fall or early winter. Then, he doubted that there was really any season besides summer in St. George. His ID implant allowed him entrance to the platform and trainâbut only during working hours. The carrier in the rear of the second car was empty, and the bicycle did foldâif not as easily as Sung had suggested. He sat down in the seat next to the carrier. A young man scurried onto the tram just before the doors closed. He wore the white short-sleeved shirt and dark
