Meanwhile, Despard left alone in the sitting-room, lit a cigarette, and rising from his chair glanced casually at the evening newspaper lying on the writing-table. Ruby had left the letter Rupert had written to his father lying on the white sheet of blotting-paper. Almost unconsciously, Despard commenced to read it. Then he picked it up and glanced hurriedly towards the door; he read it through from beginning to end. He gave a long, low whistle of astonishment, and carefully replaced the letter. He noticed the place where the first page had been blotted on the new sheet of white blotting-paper. And just below it his quick eyes saw one small word, underneath it a couple of naughts. There was nothing particularly strange or remarkable about this. He would probably never have noticed it if the blotting-paper had not been clean. But, gradually, as he stared at the one undecipherable word with the two naughts he began to feel as if there were significance about them. They stood out on the white sheet of blotting-paper. There was a small mirror standing on the mantel-piece. He took it up and held it over the blotting-pad. And he read reflected the single word between the two naughts. It was "hundred." A little way beyond it he noticed a single letter "s." Replacing the mirror he stood with his back to the fireplace, his hands deep in his trousers pockets, thinking. "Hundred," "s," and two naughts. He had seen that the slip of paper which Ruby tucked into her glove was a cheque. He was quite sure that neither she nor Rupert Dale had a hundred pounds in the world. Indeed, he knew the state of the latter’s finances better than the girl did. For only a few months ago, he had lent Rupert twenty-five pounds. He stroked his black moustache thoughtfully. Before he could solve the little problem Dale himself entered the room, followed a few minutes later by Ruby. "I came to tell you how devilish sorry I was that you had backed a loser and got plucked," Despard said; "but, hang it all, you look cheerful enough!" "So would you," Rupert cried, slapping him on the back, "if you had had a fiver on Ambuscade at a hundred to one." The frown deepened on Robert Despard’s forehead. "Look here, is this a joke or what?" "It’s no joke," Rupert laughed hysterically. "Ask Ruby, she did it for me! I’ll tell you what we’ll do. We’ll all go out and have a bit of dinner together and break a bottle of wine on the strength of it." As Rupert spoke he caught sight of the letter to his father lying on the writing-table. Picking it up quickly he tore it into a dozen fragments and threw them into the waste-paper basket. Despard watched him, and his frown deepened. "You mean to say you backed Ambuscade at a hundred to one and got paid!" "We didn’t know the result until we left the course," Rupert replied lightly. "Luckily, Ruby kept the ticket. We’re going to draw the money to-morrow. By gad, she’s saved my life! I’ve had a narrow squeak."
