CHILD'S CHILD, THE

What sort of betrayal would drive a brother and sister apart?

When Grace and her brother Andrew inherit their grandmother's house in Hampstead, they decide to move in together. It seems the obvious thing to do: they've always got on well, the house is large enough to split down the middle, and neither of them likes partying or loud music. There's one thing they've forgotten though: what if one of them wants to bring a lover into the house? When Andrew's partner James moves in, it alters the balance - with almost fatal consequences.

Barbara Vine's is the pen-name of Ruth Rendell, and  The Child's Child is the first book she has published under that name since The Birthday Present in 2008. It's an intriguing examination of betrayal in families, and of those two once-unmentionable subjects, illegitimacy and homosexuality.
