Meanwhile the outward incidents of his life were as few and simple as ever. The stream of social engagements remained indeed at its height, notwithstanding his protests of withdrawal from the world; but otherwise there is little to chronicle but the publication of his books and his yearly journeys abroad. Early in 1884 he spent some weeks in Paris, where the death of Turgenev had made a gap that he greatly felt. For the rest of the year he was occupied in writing The Bostonians, and went no further from London than to carry his manuscript into lodgings at Dover for August and September. A little later his sister Alice arrived from America, to make the experiment of life in Europe for the benefit of her now confirmed ill-health. Her presence near at hand, for the few years that remained to her, was a source of much pleasure, and also of constant anxiety, to her brother. She was a woman of rare talent and of strongly marked character; but the life of an invalid, which proved to be all she was capable of, prevented her from using her opportunities and from taking the place that would have been open to her. She lived in great retirement, at first in London, afterwards chiefly at Bournemouth and Leamington. Henry James was unwearied in his care for her; he visited her constantly, and never without keen delight in her company and her vigorous talk. His brotherly attention had yet a further reward in the summer of 1885, when she was at Bournemouth. To be near her he spent several weeks there, and was able at the same time to cultivate the society of another imprisoned invalid, close by, with whom he had already had some acquaintance. This was Robert Louis Stevenson, and the intimacy that thus arose very fortunately still survives in many admirable letters of each to the other. Stevenson's side of the correspondence, edited by Sir Sidney Colvin, is well known, and Henry James's can now be added to it; there could be no more illuminating interchange between two fine artists, so unlike in everything but their common passion.
By this time The Bostonians was beginning to appear in an American magazine, and a little later, again at Dover, The Princess Casamassima was finished. For two years Henry James now wrote nothing but shorter pieces (among them The Aspern Papers, The Lesson of the Master, The Reverberator,) with growing disconcertment as he found how tardily they seemed to appeal to editors, American or English. In the autumn of 1885 he spent his accustomed month in Paris, after which he scarcely stirred from London for another year. Early in 1886 he at last accomplished a move from his Bolton Street lodging, never a very cheerful or convenient abode, to a flat in Kensington (13 De Vere Mansions, presently known as 34 De Vere Gardens), close to the palace and the park, where he had much more agreeable conditions of light and air and quiet. He was planning, however, for another long absence in Italy, away from the interruptions of London, and this he secured during the first seven months of 1887. For most of the time he was at Florence, where he took rooms in a villa overhanging the view from Bellosguardo; and he paid two lengthy visits to Venice, staying first with Mrs. Bronson, in the apartment so often occupied by Browning, and later with Mr. and Mrs. Daniel Curtis in the splendid old Palazzo Barbaro, where years afterwards he placed the exquisite and stricken heroine of The Wings of the Dove, for the climax of her story. He returned to England, late in the summer, to settle down to the writing of The Tragic Muse--the first time, as he mentions, that he had attacked a purely English subject on a large scale. "I am getting to know English life better than American," he writes in September 1888, when he was still working upon the book, " ...and to understand the English character, or at least the mind, as well as if I had invented it--which indeed," he adds lightly, "I think I could have done without any very extraordinary expenditure of ingenuity." The end of the summer of 1888 was spent in an hotel at Torquay, which became one of his favourite retreats; and later in the autumn he was for a short while abroad, at Geneva and Paris, with a flying dip into Northern Italy. The letter to his brother, written from Geneva, with which this section closes, lucidly sums up the conclusions he had by now drawn from the experience of a dozen years of England. At the age of forty-five he could feel that he had exhausted the study of the old international distinctions, English and American, that had engaged him for so long. He was indeed to return to them again, later on, and to devote to them the final elaboration of his art; but that lay far ahead, and now for many years he faced in other directions.
