This combined précis compresses the first five “books” of Henry James’s narrative and the salon-and-morning episode that concentrates character, event and theme. The circle is compact: Kate Croy — attractive, intelligent, proud of her name and financially precarious — contends with her self‑regarding, evasive father Lionel and the material needs of her widowed sister Marian and nephews. Aunt Maud (Mrs. Lowder), a forceful Lancaster Gate patron, regulates opportunities; Merton Densher is Kate’s reflective but impecunious lover. Milly Theale, a wealthy and singular American heiress, arrives with her cultivated companion Susan (“Susie”) Shepherd; Lord Mark and Sir Luke Strett (physician) hover as influential figures.

The broader narrative sets stakes: Kate’s domestic crisis — her compromise between filial duty and social survival — invites Aunt Maud’s conditional patronage (support on terms of renouncing her father). Kate and Densher’s attachment is sincere yet materially unviable; the aunt treats both women and marriages as objects of strategic investment. Milly’s arrival amplifies tensions: her wealth, fragility and privacy make her both a target for solicitous loyalty and a pivot for social maneuvering. Sir Luke diagnoses Milly’s malady; she elects to conceal aspects of it, asking Kate for discretion and complicity. Money, reputation and sentiment collide in repeated ethical tests: private commitments are continually measured against a market of favors and appearances.

The late salon scene exemplifies these dynamics. Milly hesitates to press Kate about any correspondence with Densher — a question both practical (it might explain Kate’s reserve) and symbolic (it would recast Milly’s own silence). Mrs. Lowder, oscillating between officious mediation and unexpected warmth, urges inquiry while embodying the commercial logic of patronage: she will help, but on terms that expose social commerce. Kate is the evening’s pivot — restless, knowingly theatrical, ironic about operating “in and out of the shop‑window.” Her candid performance both flatters Milly and suggests manipulation; Milly, reassured and exposed, adopts the self‑image of “a dove,” conciliatory yet vulnerable. Aunt Maud’s ambiguous praise tests that dovelike quality, blending pity and possession.

Next morning, Milly arranges a subterfuge regarding Sir Luke — deputizing Susie to receive him — and seeks refuge in the National Gallery. There she moves between aesthetic solitude and social self‑consciousness, only to encounter Densher and then Kate entering with him. Their polished civility converts potential awkwardness into a small triumph of social ease. Luncheon at Milly’s hotel continues the performance: she delights in spontaneous American frankness, proposes an impulsive Fifth Avenue repast, and shepherds the party, even as anxiety about Sir Luke’s impending news undercuts her pleasure. The episode tightens James’s thematic work: the interplay of performance and feeling, patronage and agency, and the uneasy economy that governs intimacy and reputation.
