Yewande Omotoso’s novel, “The Woman Next Door,” explores racial tension in post-apartheid South Africa.

It’s about a pair of elderly women — one black and one white — who live in a well-to-do suburban enclave of Cape Town. They are next-door neighbors, and they despise each other.

Omotoso talks to Kurt Andersen about the book, her other career as an architect, and her experience moving to apartheid South Africa as a 12-year-old.
