Showing Undue Influence by Anita Brookner

'I had spent that morbid Sunday wondering if simple happiness were available to all and had come to the conclusion that it was not. One had to make a determined bid for it, and I did not quite know how this was done.'

Enigmatic Claire is 30 and lives alone. When she meets Martin Gibson, a faded scholar, she becomes inordinately interested. She is even more interested when she meets his wife, a far more spectacular personality. But the unexpected news of this woman's death releases emotions that were not entirely foreseen.
