The Patrician by John Galsworthy

Barbara returning from her visit to Courtier's deserted rooms, was met at Valleys House with the message: Would she please go at once to Lady Casterley?

When, in obedience, she reached Ravensham, she found her grandmother and Lord-Dennis in the white room. They were standing by one of the tall windows, apparently contemplating the view. They turned indeed at sound of Barbara's approach, but neither of them spoke or nodded. Not having seen her grandfather since before Miltoun's illness, Barbara found it strange to be so treated; she too took her stand silently before the window. A very large wasp was crawling up the pane, then slipping down with a faint buzz.
