The faint, musical whir of the little ivory ball from the roulette table caught John Bruce's attention, and he strolled in that direction. Here a “guest” was already at play. The croupier smiled as John Bruce approached the table. John Bruce smiled pleasantly in return, and sat down. After a moment, he began to make small five-dollar bets on the “red.” His fellow-player was plunging heavily--and losing. Also, the man was slightly under the influence of liquor. The croupier's voice droned through half a dozen plays. John Bruce continued to make five-dollar bets. The little by-play interested him. He knew the signs. His fellow-player descended to the supper room for another drink, it being against the rules of the house to serve anything in the gambling rooms. The croupier laughed as he glanced at the retreating figure and then at another five-dollar bet that John Bruce pushed upon the “red.” “He'll rob you of your reputation, Mr. Bruce, if you don't look out!” the croupier smiled quizzically. “Are you finding a thrill in playing the minimum for a change?” “Just feeling my way.” John Bruce returned the smile. “It's a bit early yet, isn't it?” The other player returned. He continued to bet heavily. He made another excursion below stairs. Other “guests” drifted into the room, and the play became more general. John Bruce increased his stakes slightly, quite indifferent naturally as to whether he lost or won--since he could neither lose nor win. He was sitting beside the player he had originally joined at the table, and suddenly his interest in the other became still more enlivened. The man, after a series of disastrous plays, was palpably broke, for he snatched off a large diamond ring from his finger and held it out to the croupier. “Give me--hic!--somethin' on that,” he hiccoughed. “Might as well make a clean-up, eh?” The croupier took the ring, examined it critically for an instant, and handed it back. “I'm sorry,” he said; “but you know the rules of the house. I couldn't advance anything on it if it were worth a million. But the stone's valuable, all right. You'd better take a trip to Persia.” The man replaced the ring with some difficulty upon his finger, and stared owlishly at the croupier. “T' hell with your--hic!--trip to Persia!” he said thickly. “Don't like Persia! Been--hic!--there before! Guess I'll go home!”
