In this extremity he suddenly observed a slight but significant change in the manner of the two ladies. Irene, instead of charging him with being sarcastic and horrid, and declaring herself unable to believe a word he said, began to receive his remarks with the impersonal smile which he had seen her accord to the married men of his aunt's house-parties; while Mrs. Carstyle, talking over his head to an invisible but evidently sympathetic and intelligent listener, debated the propriety of Irene's accepting an invitation to spend the month of August at Narragansett. When Vibart, rashly trespassing on the rights of this unseen oracle, remarked that a few weeks at the seashore would make a delightful change for Miss Carstyle, the ladies looked at him and then laughed.
It was at this point that Vibart, for the first time, found himself observed by Mr. Carstyle. They were grouped about the debris of a luncheon which had ended precipitously with veal stew (Mrs. Carstyle explaining that poor cooks always failed with their sweet dish when there was company) and Mr. Carstyle, his hands thrust in his pockets, his lean baggy-coated shoulders pressed against his chair-back, sat contemplating his guest with a smile of unmistakable approval. When Vibart caught his eye the smile vanished, and Mr. Carstyle, dropping his glasses from the bridge of his thin nose, looked out of the window with the expression of a man determined to prove an alibi. But Vibart was sure of the smile: it had established, between his host and himself, a complicity which Mr. Carstyle's attempted evasion served only to confirm.
On the strength of this incident Vibart, a few days later, called at Mr. Carstyle's office. Ostensibly, the young man had come to ask, on his aunt's behalf, some question on a point at issue between herself and the Millbrook telephone company; but his purpose in offering to perform the errand had been the hope of taking up his intercourse with Mr. Carstyle where that gentleman's smile had left it. Vibart was not disappointed. In a dingy office, with a single window looking out on a blank wall, he found Mr. Carstyle, in an alpaca coat, reading Montaigne.
