The unexpected guest at a party is always a good place for a mystery to start, and Mia's arrival on the scene is certainly unexpected. The Carson family are having a dinner to commemorate the birthday of their late paterfamilias, Nathaniel, when who should arrive but a young woman who claims to be his illegitimate daughter. Under the terms of Nathaniel's will, if her claim is valid, she would be entitled to an equal share of his considerable fortune, along with four of his legitimate offspring. Suspicions, and hackles, are immediately raised.
Zane, the eldest, refuses to believe Mia is who she claims. Rae, next in line, is dubious. Tommy, the youngest, says very little. Only Cassie, the narrator, is willing to accept that she may be everything she says. DNA evidence seems to prove Cassie right, but Zane remains adamant.
But as Cassie probes more deeply into Mia's past, and her motives, her own suspicions grow. Other family members are harbouring secrets, and Nathaniel had a few of his own. Skeletons tumble from cupboards at an alarming rate; everyone's a suspect, and a final cliff-top denouement that will have your heart in your mouth.
If there's one thing Sophie McKenzie is an expert on, it's how to keep up a cracking pace. That's not the only example of her skill; she also knows how to create a twist and turn on almost every page, until the poor reader doesn't know who to trust. Her characters have that scratch-them-and-they-bleed quality which makes you love them, hate them and suspect them to the bitter end – and it does get pretty bitter for just about everyone. Zane is domineering and self-centred yet with vulnerable spots. Rae is brittle but has a softer side. Tommy is the epitome of the spoiled, selfish youngest son, but still manages to be likeable. Cassie tries to be the sensible one, but even she has her insecurities. And Mia, sweet, accommodating Mia, seems a little too good to be true. Is she who she claims to be, or is she just playing a part?
This is a psychological thriller packed with the
kind of misdirection that will keep you guessing right to the last few pages,
even though the clues are there all along, buried just deep enough to fool the
most experienced crime fiction reader. I challenge you to put it down before
you've unearthed the truth.
