The Walsh Sisters author Marian Keyes has said that she “never considered” the possibility that the BBC’s new TV adaptation might not be to her liking. Adapted from her books, the series follows a “dysfunctional, but deeply loveable” family comprised of five sisters, their devout mother and bemused father, all of whom are based in Dublin.
