“She is awake…”
That’s a great start to a novel! Who is ‘she’, and why is her awakening so important, so ominous? Sadly, after that this never really gets any better.

The Leviathan is set in Norfolk and is told in two threads, one set in a time of relative peace in 1703, and one sixty years earlier during the English Civil War. The narrator of both tales, Thomas Treadwater reflects on his time serving in Cromwell’s army. During a seasonal break in the fighting he returned home to nurse his wounds. His return was hastened by a letter from his sister who suspected a new servant of ‘drawing our father into corruptions’, alleging she was using witchcraft to do so. By the time Thomas reached their remote farm his father had had a stroke, the farm was in chaos, and the servant had been arrested on suspicion of being a witch. Thomas recollects his struggles to come to terms with what had happened as events snowball beyond his control.
There are a number of issues with The Leviathan, some of which I can discuss avoiding spoilers, others, sadly not. If that is likely to be a problem for you, and if you are planning to read the book, (and I admit, the premise is intriguing) don’t read on.
For a novel set in North Norfolk, an area of the country with a very specific geography, a sense of place is almost completely lacking. Apart from the fact that the Treadwater farm is set in remote countryside, we could be almost anywhere. What is so frustrating about this is that this part of the world has such a haunting atmosphere – huge skies, towering flint churches that seem wildly out of scale with their villages, coastal marshes and crumbling cliffs. Although most of the drainage windpumps that survive to this day were built later, at this time (i.e. in the seventeenth century) there would have been windmills stalking over across the flat landscape. What a missed opportunity this was. The sense of the period is captured very effectively – the world turned upside down – with parliament challenging the supreme authority of the monarch, but the sense of place is missing.
The novel opens as a fairly conventional story of witchcraft and witch-finding. The sinister and zealous Witchfinder Rutherford is introduced, but any expectation that he is going to be the novel’s villain is confounded when he goes missing, shortly after having proposed to Thomas’s young sister Esther. No-one seems particularly troubled by his absence, and that storyline is quietly dropped, as eventually is the witchcraft thread of the novel altogether. Why Esther would have accepted Rutherford’s proposal when she is – we later find out – not in any position to do so, is unexplained. Certainly the engagement is short lived! (Just to be clear, it is later suggested Esther had a sinister motive in accepting Rutherford, or in getting close to him, but the presentation of her acceptance is completely at odds with this motive. It appeared very inconsistent characterisation).
The introduction of John Milton to the novel as a character who helps resolve the mystery of the Leviathan is unconvincing and strange. He seems shoe-horned into the novel to provide it with some period detail, although his future as one of England’s greatest poets as well as his role as a radical figure within the Commonwealth Government goes largely unmentioned. Using historical figures as detectives in popular fiction has become a bit of a cliché recently, but Milton’s contribution to resolving the novel’s central mystery is in any event marginal. His presence is a wasted opportunity.
Thomas eventually finds out that his sister, Esther, has become possessed by a devil or demon. Their father rescued her from a shipwreck sixteen years earlier, and all this time the demonic entity has been lying dormant, sparked into life by the envy Esther feels towards her father’s new (and attractive) young servant. This makes some sense – Wikipedia tells me that Thomas Aquinas described the biblical Leviathan as the “demon of envy, first in punishing sinners”. But it is never made clear what the relationship is between the demonic entity that possesses Esther and the Leviathan itself, an enormous ship-crushing sea-monster. If I found The Essex Serpent disappointing in its non-existence, the literal appearance of the Leviathan was in many ways even more disappointing, and certainly less convincing. For horror to be effective it has to be credible, and while the ideas of witchcraft and possession have some basis in historical fact and can be explained by reference to actual phenomena, real-life sea-monsters summoned from the deep by demons are harder to believe.
My theory is that there was no sea monster, no Leviathan in the first draft of this novel. It was a story about witchcraft and possession, about faith and scepticism. The appearance of the great sceptic Milton in that novel makes complete sense. But then I suspect an editor read the novel in draft and suggested some changes that would make it more marketable (which to be fair is their job!). The book trade must have been looking for a successor to The Essex Serpent for some time (in the same way that I am sure editors are considering at this very moment the first chapters of The Tuesday Lunchtime Homicide Association penned by a moderately famous television presenter!). The Leviathan’s marketing leverages its apparent similarity to The Essex Serpent, not least in the serpentine design of the book’s cover. It’s not a coincidence that it was displayed in my local Waterstone next to copies of the Perry novel, nor that Goodreads describes it as “perfect for fans of The Essex Serpent.”
So The Leviathan 2.0 was (my theory goes) born, in which a storyline about a sea-serpent was grafted clumsily onto a witchcraft/demonic possession gothic horror novel. The joints show and creak. The remaining elements of the original horror story show some fairly obvious borrowing from nineteenth century gothic. As in Jane Eyre a mad-woman kept trapped in the attic breaks free and destroys the family home with fire. There’s also more than a hint of Wuthering Heights in the storyline whereby a foundling is taken in by a family living in a remote farmhouse who grows up with destructive urges, undermining the adoptive family from within.
There are some other issues with the unevenness of the narrative. When Thomas first returns to the family farm he sees dozens of sheep lying dead in the fields. The illness that has swept through the herds is quickly forgotten (as is the unpleasant job of disposing of the carcasses) and was obviously just added for atmosphere. Thomas’s infected and agonising war wound quickly disappears after a poultice is applied and he has a few days bed rest. And the end of the novel is confused and ambiguous. Gothic horror is always going to struggle in this context – either the author can resolve matters with a naturalistic/scientific explanation (it was the crusty old janitor wearing a mask all along) or the supernatural is real, witches and magic exists, and the reformation was all a lie. I’m not sure there is a correct answer to that conundrum, but if an author is going to invite us to believe in monsters and demons then they need to be summoned with a little more conviction.
