First published back in December of 2025, British author Guy Portman’s novel ‘Avengement’ formed the second book in the ‘Necropolis’ series, featuring the psychopath ‘Dyson Devereux’. Although ‘Necropolis’ (2014) was the first book within the series to be written and published, ‘Avengement’ – and indeed the previous instalment in the series ‘Genesis’ (2025) – formed prequels to the original trilogy.
Also of note is that there’s also a three-book spinoff series called the ‘Emergence’ series which featured the young psychopath ‘Horatio’ who was Dyson Devereux son.
DLS Synopsis:
It’s 1996 and Dyson Devereux has just completed his bachelor’s degree in Classical Studies. It’s now time for him to find a job. However, first his priority is passing his driving test. It’s an essential step towards his larger goal: to travel to his childhood hometown and take revenge on the three he hates the most in the world – Treacherous Trenton, Virulent Veronica and Conniving Clementine.
Dyson hasn’t forgotten what they did to him a decade ago. The misery they caused him. The former proprietors of the Tollington Twins Teahouse would be first, then Dyson would move onto his nemesis – the local GP who took advantage of Dyson’s mother, which resulted in her drug addiction and eventual death.
That was the plan. It was time for him to get packing, get moving, and reap his vengeance. Although first he had a few minor things to deal with. His girlfriend, Emily, was becoming tiresome. Irritable even. Dyson needed to leave his student accommodation behind and start out in adult life proper.
The sleepy rural town of Tollington, where Dyson had spent his formative years, is about to have a wake-up call in comeuppance that’ll have the locals gossiping for weeks. Dyson’s return to the town will leave a mark unlike any other.
Dyson Devereux is out for revenge. He’s gaining confidence, refining his charm, and getting a deeper taste for murder. Dyson Devereux has already killed – now it’s time for him to kill again. Now it’s time for him to become the serial killer he’s always wanted to be…
Following on from the highly entertaining prequel novel ‘Genesis’ (2025) – which ideally should be read first when embarking upon the series – we have this second instalment which takes us through Dyson Devereux’s life immediately post-University.
If you’ve already read the first book, or indeed any of the other books in the ‘Necropolis’ series, perhaps as and when the latter instalments were originally released, then you will no doubt know the tone and style to expect. Essentially, we have a dark, satirical comedy about a suave, charming and somewhat sophisticated serial killer.
However, in this book we see a tad more of Dyson’s lack of self-awareness coming through. It’s again, written from Dyson’s perspective, telling his story from behind his own eyes. But through this we glimpse the reaction of others to his increasingly self-absorbed behaviour, more and more. His frequent moments of daydreaming and sudden outbursts of laughter, as he internally reminisces about past glories or comical ponderings. It’s a detachment from his surroundings which is frequently observed by others.
We also see glimpses of Dyson exhibiting a mild form of the Dunning–Kruger effect, where his over-confidence leads him to believe he’s unquestionably the best at everything he does, but reality now appears to be a tad different. His ability with driving, both whilst undergoing his driving test, as well as immediately post passing, provides us with a good sight of this, as does his first attempts at trying to land himself with a decent job. And it makes us wonder what else Dyson is seeing through a distorted perspective. What else he’s not in reality the absolute epitome of?
I’m hoping if you’re reading this review, then you’ve already read the aforementioned prequel novel. If not, I advise you to stop reading this review, and instead pick up the first book - ‘Genesis’ (2025) – before reading any more of my ramblings on this second instalment. Mild spoilers regarding the first book await. You are warned!
So, as we saw in the previous book, Dyson’s had his first kill during his early teen years. His nasty and vindictive cousin – Beatrice – takes a tumble over a cliff edge at Beachy Head courtesy of our protagonist. One kill does not a serial killer make! But we know there will be more. And by the end of the first book, we’re pretty sure we know who Dyson will have his eyes upon – the Tollington Twins and of course the corrupt sociopath GP Trenton.
The planned murder of these individuals forms the main focus of this particular instalment. However, as always, we have other subplots and parallel running story arcs. We have the reignition of a relationship with Amelia Burlington – who Dyson hasn’t seen for eight years, since he left Tollington. Ameila’s now the epitome of a young professional in her early twenties. An estate agent who spends most of her time hanging out with her boss and other colleagues – always boozing, always waking up the next day with a pounding hangover.
Their relationship, as well as others in Dyson’s life, help to emphasise and exhibit Dyson’s carefree and sociopathic nature. His lack of connecting with anyone other than merely at a surface level. His inability for him to really be there in the same room as them, despite being physically present. Author, Guy Portman, doesn’t make a big song and dance of this, but instead inserts the subtleties of his beloved character’s sociopathic personality and traits.
There’s a very tight connection between this book and the previous one. The continuation of the Garbage Pail Kids-style nicknames that Dyson prescribed to characters from when he was a young teen. We even see good old Edgerton-Smythe making an appearance in the book.
What we have in this book is a voyeuristic view of Dyson’s life as he matures further. Where we see his over-confidence in his abilities coming to fruition more and more. We see how much he’s able to project himself and progress in life largely through this confidence, but slowly, this starts to crumble when he pushes his natural flair for getting away with shit too far.
It’s again an insanely entertaining read. Laced with dry wit throughout. Dark humour that’ll have you roaring with laughter in more than a few places.
It’s now edge-of-the-seat time as we wait for the third and final book in this prequel trilogy to conclude the early years of Dyson Devereux, and tie in the final links to the spectacular novel that started it all – ‘Necropolis’ (2014).
The novel runs for a total of 153 pages.
