Black Thorn by Sarah Hilary
Sarah Hilary has this amazing ability to leave the reader floundering between law, morality and ethics. I never quite know who I’m rooting for. Who’s in the right or the wrong? I come to different answers depending on the lens I’m viewing it through – someone can be within the law whilst being morally questionable. I often find myself stopping to wonder if I even like any of the characters. This is one of those stories that expose the dark underbelly of what looks like the dream neighbourhood. The houses at Black Thorn are like those you see in the Omaze giveaway adverts. The opening scenes of a neighbourly barbecue show us two very different narratives: the jolly and friendly neighbours enjoying each other’s hospitality; the neighbour who breaks into the party with a grudge. Is Luke Dearborn a nutter and a conspiracy theorist? Is there something rotten at the heart of this dream housing development?
The timeline slips back and forth from pre to post-abandonment. Both timelines race towards Day 0, the day of ‘abandonment’ and possibly the truth about what has been happening, both to the houses and the people living there. I was interested in the word ‘abandonment’ because it feels as if it’s in the wrong context. It describes the development as something with feelings rather than bricks and mortar. Also ‘abandonment’ suggests an element of choice, when actually the residents were forced to leave by the authorities. It was an evacuation more than abandonment, a word that gives the sense of an unloved child rather than an inanimate house. Adrian is affected the most because not only did he sell the development, he bought one for his family. This leaves him on site for all the problems to come to his door, creating enormous stress for all of them. It’s almost as if Adrian fell for his own sales patter. He’s sold the units as state of the art living with coastal views through the huge glass sections at the back of the house. It seems a bleak setting to me, the last places before you drop off the edge of the world! They’re also described as luxury, but it feels like a Scandi design, more minimalist. To me luxury means softness, comfort, colour and warmth. These rooms seem to be more about impressing others than thinking what is comfortable for long term residents. Maybe they’d be better holiday homes. Even their gimmick of fake diamonds scattered throughout seems wrong, they’re hard and cold and not something you’d want to tread on in bare feet. Trevor, his business partner, manages to escape this by going off site or bedding down in one of the unsold units where he can’t be seen. In our flashbacks we know that six people die, but what of? Is there poison in the heating systems or is it carbon monoxide poisoning? Adrian clearly feels responsible, falling into a deep depression. Trevor is still hanging around, being cocky and unwilling to admit that corners were cut or mistakes made. Through Agnes we slowly untangle a whole web of deceit and lies, but Trevor is one of those people where nothing sticks. It’s Adrian who might end up taking the blame.
The character I seemed to view things through was Agnes, because I think she represented the reader – an outsider, lost, in the dark and vulnerable. She’s part of a family – her father Adrian was the salesman for this development – but has lived in London for a number of years. She’s had some distance from the project and can look at it with fresh eyes. Yet for a girl whose in her twenties, Agnes seems very naïve and a bit lost. We know that Agnes has split with her girlfriend so may be feeling vulnerable, but she is suspicious of her family’s new home at once. It’s almost as if her nervous system is affected by them. There’s something in the walls, there are trenches in the gardens and her pet rabbit dies. In the aftermath, her family are now living in a caravan park near her friend Errol and his grandmother Bette who was the cleaner at Black Thorn. Her friendship with Errol is warm and open and she’s welcomed into their caravan in a way that feels natural compared to the fractured and strained relationships elsewhere. Her father is almost catatonic and her mother is working round the clock trying to keep her family safe. Agnes is desperately trying to keep younger brother Christie safe, but he is lured back to the development. He walks along the coast road every day and breaks into a house, slowly going through what’s left and choosing his favourite items to take back to the caravan. Agnes feels she must protect him, particularly from Trevor who seems to exert a malign influence over Christie. Agnes knows first hand exactly how far Trevor will go to get what he wants.
As always the author’s writing is incredible. She keeps the reader on edge, never knowing who is lying or who’s in the wrong. She gives us ambiguous characters like Erica who masqueraded as a butcher’s assistant to deliver meat for the BBQ, keen to stay to show them how best to cook it and get to know the residents. Yet she’s not who she says she is and her deceit will place her in danger. Even the person we spend most time with, Agnes, is hard to connect with. As in real life, everyone has their faults, but it isn’t just that. I struggled because no one seemed to be showing human feelings or genuineness. As a result there were a couple of points in the book where I didn’t feel enough for the characters to be completely invested in the story so it stalled a little for me. However, I did want to know what exactly had happened in the houses and it was that need to know the truth that kept me reading. I had to wait till the very end for some characters to show how they really felt; until now feeling totally numb and shocked, or trying to hold it together and be the strong one for everyone else. This was an addictive read and did keep me guessing till the final page.
