Meanwhile Delapine continued passively to watch the play for about twenty minutes. At the end of that time he quietly took out of the envelope three bank notes of 100 francs each, and placed one on each of the three consecutive numbers 7, 28 and 12, while putting a 1,000 franc note on each of the squares, red, impair, and manque, and then rapidly turning his head concentrated his gaze on the little ball which had just fallen on to the larger wheel. The ball bobbed frantically about, and at length fell into No. 7. "Sept, rouge, impair et manque," shouted the croupier, as he raked in Delapine's pieces on 28 and 12, and tossed seven notes of 500 frs. each on to No. 7, and 1,000 fr. notes on to "rouge," "impair," and "manque." Delapine's stake of 3,300 frs. was now increased by 6,300 frs.[21] Whispering a few words to Renée, telling her what numbers to back, and without troubling himself in the least about his own gains, he once more turned his attention to the little ball. Renée immediately did as he had told her and placed the maximum allowed--180 frs.--on number 7, leaving the money with the gains added on each of the single chances, rouge, pair and manque. Round went the wheel again, and the little ball hopped about as before. Delapine did not move his head but continued to gaze steadily on the ball. Five times running Renée repeated the process, each time leaving the maximum--6,000 frs.--on each even chance, and the maximum on the single number. At last she ceased for a moment and counted the notes in hand. She had won 120,000 francs. All this time Delapine had remained motionless with his eyes fixed like a carved Buddha. At length he leaned over and whispered to Renée, who immediately transferred the maximum stakes to three fresh numbers and different squares. The whole thing was done so quietly and so unobtrusively that only an onlooker who had been specially regarding him could have noticed that Delapine had made the slightest movement. Occasionally he would take half-a-dozen gold pieces and rapidly throw them on to as many squares or numbers, without troubling his head in the least as to whether they won or lost. But Renée was winning so fast that she became the centre of attraction for the crowd which grew more and more dense at the table, little dreaming that it was the quiet professor at her side and not the player herself who was manipulating the stakes, and who was responsible for all her marvellous good fortune.
