The Time of the Angels by Iris Murdoch

Carel is a widowed rector presiding over a London church destroyed during the war. The rectory is home to an array of residents: his daughter, Muriel; his beautiful invalid ward, Elizabeth; their West Indian servant, Pattie; Eugene, a Russian emigre, and his delinquent son, Leo. Carel's brother, Marcus, is co-guardian of Elizabeth, but his attempts to get closer to the rector are constantly rebuffed.
