The Child's Child

When Grace and her brother Andrew inherit their grandmother's house in Hampstead, they decide to move in together. 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.
