David nodded. ‘We have three children now. They are upstairs with their nurses. And as you see, we await a fourth.’ He glanced fondly at his wife who nodded a little smugly. ‘You must see Louis, my dear. He is the most beautiful child.’

Louisa nodded. ‘I would expect no less.’ She hoped they were not going to launch into a long explanation of how they knew one another for the benefit of their hostess. But Sarah, it appeared, already knew the story of Louis’s dramatic birth. Either out of great tact or by accident she adroitly changed the subject.

‘The gentlemen are going out on the hill with the guns tomorrow, Louisa. So I thought perhaps we would spend a quiet day in the gardens or maybe take a short carriage drive?’ She raised an eyebrow at their newly arrived guest. ‘Only if Katherine feels like it, of course.’ A well-built, attractive woman with elegantly dressed greying hair, Sarah surveyed her guests calmly, her blue eyes shrewd.

Before Katherine could respond to her suggestion the door opened and another woman walked into the room. David Fielding’s sister, Venetia. Louisa sighed. The younger woman’s figure had thickened slightly in the last seven years in spite of her tightly laced corset, her face had hardened, the corners of her mouth were drawn down, the eyes were a trifle deeper set, but she was still a beautiful woman. In spite of herself, as she stepped forward to greet her, Louisa glanced at her hand. No wedding ring. Obviously not, if she was still trailing around after her brother and his wife.

Venetia’s smile did not quite reach her eyes as she greeted Louisa. Her kiss was perfunctory and did not do more than brush the air beside Louisa’s cheek. ‘How are you now?’ Four innocuous words, but loaded with innuendo and dislike.

‘Well, thank you.’ Louisa smiled and turned to find a seat. A dozen spirited questions and retorts flashed through her mind. All were instantly rejected. Silence was the most dignified route.
