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.

The Child’s Child is an intriguing examination of betrayal in a family, and of those two once-unmentionable subjects, illegitimacy and homosexuality.
