The echoing grove - Rosamond Lehmann

Two sisters:
Madeleine and Dinah.
One husband:
Rickie Masters.
For many
years now, Dinah, exotic and sensual, has conducted a clandestine affair with
Rickie. Madeleine, calm and resolute, has accepted that her marriage has been of limited success.
Rickie's sudden death makes widows of both sisters in this highly imaginative novel that explores with extraordinary insight the sublimity, the rivalry and the pain of personal relationships.

'She makes a mood, an atmosphere, which is never forgotten . . . The inner voice of women talking to themselves about their love affairs, knowing that it is hopeless, having to go ahead anyway, expecting the end as soon as it begins. That, of course, is what Rosamond Lehmann does best' Sunday Times
