He signed his own name to the register, but didn't add: "Federal Bureau of Investigation" after it. After all, he thought, he was there unofficially. And even though gambling was perfectly legal in Nevada, the thought of the FBI still made many of the club owners just the least little bit nervous. Instead, Malone gave a Chicago firm as his business address--one which the FBI used as a cover for just such purposes. The clerk looked at him politely and blankly. "A room in the Tower, sir?" he said. Malone shook his head. "Ground floor," he said. "But not too far from the Tower. I get airsick easily." The clerk gave Malone a large laugh, which made him uncomfortable and a little angry. The joke hadn't been all that good, he thought. If he'd ordered a top-price room he could understand the hospitality, but the most expensive rooms were in the Tower, with the outside cabins running a close second. The other rooms dropped in price as they approached the periphery of the main building. "A humorist, sir?" the clerk said. "Not at all," Malone said pleasantly, wishing he'd signed with his full occupation and address. "I'm a gravedigger. Business has been very good this year." The clerk, apparently undecided as to whether or not to offer congratulations, settled for consulting his registry and then stabbing at a button on a huge and complex board at his right. A key slid out of a slot and the clerk handed it to Malone with a rather strained smile. "10-Q," he said. "You're very welcome," Malone said in his most unctuous tones. He took the key. The clerk blinked. "The bellman will take you to your rooms, sir," he said in a good imitation of his original voice. "There are maps of the building at intervals along the halls, and if you find that you have become lost you have only to ask one of the hall guides to show you the proper directions." "My, my," Malone said. The clerk cleared his throat. "If you wish to use one of the cars," he went on in a slightly more unsteady voice, "simply insert your key in the slot beneath one of the wall maps, and a car will be at your service." Malone shook his head and gave a deep sigh. "What," he said, "will they think of next?" * * * * * Satisfied with that for an exit line, he turned and found that the bellman had already taken his luggage from the robot redcap and put it aboard a small electric car. Malone got in beside him and the bellman started the vehicle down the hallway. It rolled along on soft, silent tires. It, too, was gilded. It didn't move very fast, Malone thought, but it certainly beat walking.
