I Thought I Knew You

UK Publisher: Pan Macmillan

Who do you know better? Your oldest friend? Or your child?

And who should you believe when one accuses the other of an abhorrent crime?

Jules and Holly have been best friends since university. They tell each other everything, trading revelations and confessions, and sharing both the big moments and the small details of their lives: Holly is the only person who knows about Jules’s affair; Jules was there for Holly when her husband died. And their two children – just three years apart – have grown up together.

So when Jules’s daughter Saffie makes a serious allegation against Holly’s son Saul, neither woman is prepared for the devastating impact this will have on their friendship, their families, and everything they believe in.

Especially as Holly refuses to accept her son is guilty.

For fans of He Said/She Said and Anatomy of a Scandal, Penny Hancock’s I Thought I Knew You is about secrets and lies – and whose side you take when it really matters.

‘A wonderfully nuanced, captivating page-turner.’ – Paula Daly

‘This a fabulous premise, expertly delivered. It takes psychological noir in a new and unnerving direction, constantly leaving you on edge and fearful for characters you care about.’ – Craig Robertson

‘I Thought I Knew You is a compelling ‘did-he-do-it?’story, raising the topical issues of consent, teenage vulnerability and the complications of parenting a teenager. At the same time it dares to expose female friendship – so valuable to most women – as intrinsically fragile.’ –WI Life magazine
