It was to prove, however, on the morrow, quite consistent with the spirit of these words that, the party at Matcham breaking up and multitudinously dispersing, he should be able to meet the question of the social side of the process of repatriation with due presence of mind.  It was impossible, for reasons, that he should travel to town with the Assinghams; it was impossible, for the same reasons, that he should travel to town save in the conditions that he had for the last twenty-four hours been privately, and it might have been said profoundly, thinking out.  The result of his thought was already precious to him, and this put at his service, he sufficiently believed, the right tone for disposing of his elder friend’s suggestion, an assumption in fact equally full and mild, that he and Charlotte would conveniently take the same train and occupy the same compartment as the Colonel and herself.  The extension of the idea to Mrs. Verver had been, precisely, a part of Mrs. Assingham’s mildness, and nothing could better have characterised her sense for social shades than her easy perception that the gentleman from Portland Place and the lady from Eaton Square might now confess, quite without indiscretion, to simultaneity of movement.  She had made, for the four days, no direct appeal to the latter personage, but the Prince was accidental witness of her taking a fresh start at the moment the company were about to scatter for the last night of their stay.  There had been, at this climax, the usual preparatory talk about hours and combinations, in the midst of which poor Fanny gently approached Mrs. Verver.  She said “You and the Prince, love,”—­quite, apparently, without blinking; she took for granted their public withdrawal together; she remarked that she and Bob were alike ready, in the interest of sociability, to take any train that would make them all one party.  “I feel really as if, all this time, I had seen nothing of you”—­that gave an added grace to the candour of the dear thing’s approach.  But just then it was, on the other hand, that the young man found himself borrow most effectively the secret of the right tone for doing as he preferred.  His preference had, during the evening, not failed of occasion to press him with mute insistences; practically without words, without any sort of straight telegraphy, it had arrived at a felt identity with Charlotte’s own.  She spoke all for their friend while she answered their friend’s question, but she none the less signalled to him as definitely as if she had fluttered a white handkerchief from a window.  “It’s awfully sweet of you, darling—­our going together would be charming.  But you mustn’t mind us—­you must suit yourselves we’ve settled, Amerigo and I, to stay over till after luncheon.”
