The Family Game
THE RULES
1. Listen carefully
2. Do your research
3. Trust no one
4. Run for your life
Harriet Reed is newly engaged to Edward Holbeck, the heir to an extremely powerful American family.
When Edward’s father hands her a tape of a book he’s been working on, she is desperate to listen.
But as she presses play, it’s clear that this isn’t a novel. It’s a confession to murder.
Feeling isolated and confused, Harriet must work out if this is all part of a plan to test her loyalty. Or something far darker.
Because this might be a game to the Holbeck family - but games can still be deadly.

Mr Nobody
When a man is found on a Norfolk beach, drifting in and out of consciousness, with no identification and unable to speak, interest in him is sparked immediately. From the hospital staff who find themselves inexplicably drawn to him; to international medical experts who are baffled by him; to the nationalpress who call him Mr Nobody; everyone wants answers. Who is this man? And what happened to him?
Neuropsychiatrist Dr Emma Lewis is asked to assess the patient. This is her field of expertise, this is the chance she’s been waiting for and this case could make her name known across the world. But therein lies the danger. Emma left this same small town in Norfolk fourteen years ago and has taken great pains to cover all traces of her past since then.
But now something – or someone – is calling her back. And the more time she spends with her patient, the more alarmed she becomes.
Has she walked into danger?
