Standing alone at Browns party，Anna Mackintosh thought about her husband Edward，establishing him clearly in her mind’s eye. He was a thin man，forty-one years of age，with fair hair that was often untidy．In the seventeen years they’d been married he had changed very little：he was still nervous with other people，and smiled in the same shy way，and his face was still almost boyish．

She believed she had failed him because he had wished for children and she had not been able to supply any．She had been annoyed for this fact over the years and in the end，quite some time ago now，she had consulted Dr.Abbat at Edward’s request.

In the Browns’rich living room，its walls and ceilings giving out a bright light with a metallic surface of imitation gold，Anna listened to dance music coming from a tape recorder and continued to think about her husband．

In a moment he would be at the party too，since they had agreed to meet there，although by now it was three quarters of an hour later than the time he had planned to come.

The Browns were people he knew in a business way，and he had said he thought it wise that he and Anna should attend this gathering of theirs. She had never met them before，which made it more difficult for her，having to wait about，not knowing a soul in the room．

When she thought about it she felt herself unfairly treated，for although Edward was kind to her and always had been，it was far from thoughtful to be as late as this. Because of her nervous condition she felt afraid and had developed a sickness in her stomach．She looked at her watch and sighed．
