Chatto & Windus, 1971
Comparing Murdoch with Lessing...
Scenes which made me think of Doris Lessing:
-Mrs. Carberry vs retarded son in The Fifth Child
-Charlotte vs short story about elderly aunt who always helped everyone and knew no one cared about her
-Gracie & tree vs short story about boy who made love with a tree all the time
-Matthew/Mavis vs Mark/Martha
Both authors were born in 1919.
Many characters vs fewer characters but more developed, especially Lessing herself.
Existential vs more alive (I prefer Lessing)
