Edwin Page, a fussy middle-aged professor, no sooner bids farewell to his obstetrician wife, Cecilia, who accepted a fellowship abroad, when his new neighbors, Mrs. Botts and her sexy, twentyish daughter, Leila, arrive. Since they're locked out of their house, Edwin invites them in-and then can't get them to leave. He becomes obsessed with Leila and convinces himself that she is a perfect surrogate mother for the childless Cecilia. "Wickedly amusing ...subversive" (New York Times Book Review), The Sugar Mother undoes the institution of marriage.
