Nor could the reason be that Alice was beautiful and attractive. One could have imagined it if Mrs. Robbie had been like—say, Mrs. Winnie Duval. It was easy to think of Mrs. Winnie taking a fancy to a girl, and spending half her fortune upon her. But from a hundred little things that he had seen, Montague had come to realize that the Robbie Wallings, with all their wealth and power and grandeur, were actually quite stingy. While all the world saw them scattering fortunes in their pathway, in reality they were keeping track of every dollar. And Robbie himself was liable to panic fits of economy, in which he went to the most absurd excesses—Montague once heard him haggling over fifty cents with a cabman. Lavish hosts though they both were, it was the literal truth that they never spent money upon anyone but themselves—the end and aim of their every action was the power and prestige of the Robbie Wallings. “They do it because they are friends of mine,” said Oliver, and evidently wished that to satisfy his brother. But it only shifted the problem and set him to watching Robbie and Oliver, and trying to make out the basis of their relationship. There was a very grave question concerned in this. Oliver had come to New York comparatively poor, and now he was rich—or, at any rate, he lived like a rich man. And his brother, whose scent was growing keener with every day of his stay in New York, had about made up his mind that Oliver got his money from Robbie Walling. Here, again, the problem would have been simple, if it had been another person than Robbie; Montague would have concluded that his brother was a “hanger-on.” There were many great families whose establishments were infested with such parasites. Siegfried Harvey, for instance, was a man who had always half a dozen young chaps hanging about him; good-looking and lively fellows, who hunted and played bridge, and amused the married women while their husbands were at work, and who, if ever they dropped a hint that they were hard up, might be reasonably certain of being offered a cheque. But if the Robbie Wallings were to write cheques, it must be for value received. And what could the value be?
