The octagon room at Sir Robert Chilterns house in Grosvenor Square.[The room is brilliantly lighted and full of guests. At the top of the staircase stands LADY CHILTERN, a woman of grave Greek beauty, about twenty-seven years of age. She receives the guests as they come up. Over the well of the staircase hangs a great chandelier with wax lights, which illumine a large eighteenth- century French tapestrymdash;representing the Triumph of Love, from a design by Bouchermdash;that is stretched on the staircase wall. On the right is the entrance to the music-room. The sound of a string quartette is faintly heard. The entrance on the left leads to other reception-rooms. MRS. MARCHMONT and LADY BASILDON, two very pretty women, are seated together on a Louis Seize sofa. They are types of exquisite fragility. Their affectation of manner has a delicate charm. Watteau would have loved to paint them].
