Mr. Spragg appeared to search his memory for confirmation of the fact.  “I believe he used to be round there at one time.  I’ve never heard any good of him yet.”  He paused at a crossing and looked probingly at his son-in-law.  “Is she terribly set on this trip to Europe?”

Ralph smiled.  “You know how it is when she takes a fancy to do anything—­”

Mr. Spragg, by a slight lift of his brooding brows, seemed to convey a deep if unspoken response.

“Well, I’d let her do it this time—­I’d let her do it,” he said as he turned down the steps of the Subway.

Ralph was surprised, for he had gathered from some frightened references of Mrs. Spragg’s that Undine’s parents had wind of her European plan and were strongly opposed to it.  He concluded that Mr. Spragg had long since measured the extent of profitable resistance, and knew just when it became vain to hold out against his daughter or advise others to do so.

Ralph, for his own part, had no inclination to resist.  As he left Moffatt’s office his inmost feeling was one of relief.  He had reached the point of recognizing that it was best for both that his wife should go.  When she returned perhaps their lives would readjust themselves—­but for the moment he longed for some kind of benumbing influence, something that should give relief to the dull daily ache of feeling her so near and yet so inaccessible.  Certainly there were more urgent uses for their brilliant wind-fall:  heavy arrears of household debts had to be met, and the summer would bring its own burden.  But perhaps another stroke of luck might befall him:  he was getting to have the drifting dependence on “luck” of the man conscious of his inability to direct his life.  And meanwhile it seemed easier to let Undine have what she wanted.

Undine, on the whole, behaved with discretion.  She received the good news languidly and showed no unseemly haste to profit by it.  But it was as hard to hide the light in her eyes as to dissemble the fact that she had not only thought out every detail of the trip in advance, but had decided exactly how her husband and son were to be disposed of in her absence.  Her suggestion that Ralph should take Paul to his grandparents, and that the West End Avenue house should be let for the summer, was too practical not to be acted on; and Ralph found she had already put her hand on the Harry Lipscombs, who, after three years of neglect, were to be dragged back to favour and made to feel, as the first step in their reinstatement, the necessity of hiring for the summer months a cool airy house on the West Side.  On her return from Europe, Undine explained, she would of course go straight to Ralph and the boy in the Adirondacks; and it seemed a foolish extravagance to let the house stand empty when the Lipscombs were so eager to take it.
