Trevannock is my alternate history novel: the transatlantic slave trade, reversed.
The ledgers taught me that moral distance is a technical problem. It can be engineered. It can be maintained across thousands of miles and decades through the simple application of administrative language, through the substitution of the human for the fungible, through numbers and categories and descriptions so precise that they omit the only thing that matters.
I discovered this while researching the world of Trevannock, the alternate history novel set in seventeen eighty-two Cornwall. The real transatlantic trade in human beings generated vast documentation: manifests, insurance policies, cargo inventories, port records, letters of credit. These documents are terrible things to read. Not because they are poorly written. They are written with absolute clarity. A man is listed as a unit. A woman is itemised. The weight is recorded. The price is noted. The mortality risk is calculated and hedged. Everything is there except the person.
This is the crucial insight, I think, for any novelist engaging with historical atrocity: the perpetrators created a language to make the unbearable routine. They built bureaucratic structures specifically to create distance between the decision-maker and its human cost. The paperwork is not incidental to the horror. The paperwork is part of how the horror was possible.
When I set out to construct the alternate history in Trevannock, I wanted to interrogate this mechanism. What if the geographic and economic positions were reversed? What if an African power, the Adunbi Imperium, occupied the position of expansionist colonial force? What would their records look like? Would they use the same techniques of abstraction? Would they create the same distance between official language and individual suffering?
The answer, I found, had to be yes. The ledgers do not belong to any particular nation or culture. They are the natural language of commerce in coercion. An empire that seized people would reach for the same tools. They would inventory cargo the same way. They would calculate insurance against losses in the same manner. The language would shift to accommodate different alphabets and different ports, but the structure would remain. This is what makes the mechanism so poisonous: it works. It is portable. It is teachable.
I made a decision early in my alternate history novel that affected everything that followed: I would include fragments of these documents. I would let the ledgers speak in their own voice. Not as extended quotations, but as breaks in narrative, as administrative interruptions in the human story. A manifest here. A price list there. An insurance schedule. A shipping log.
The effect on the book's emotional texture was immediate and unsettling. The presence of these documents does not make the alternate history feel more real, exactly, though it does that. It does something more disquieting: it creates a kind of moral vertigo. The reader passes from intimate narrative into bureaucratic abstraction and back again. The contrast itself becomes the point. You move from a man's thoughts, his fear, his memories, to a ledger entry that reduces him to cargo and weight and financial exposure. Then you return to his interior life. The whiplash is not accidental.
This is what I mean by moral distance being a technical problem. The ledgers in Trevannock are not there to provide historical detail or to establish the texture of the period. They are there because they are the mechanism by which ordinary people participated in extraordinary cruelty. A port official did not need to witness violence to be complicit. He needed only to file the paperwork. He needed only to ensure that the categories were correct, the arithmetic accurate, the notation clear. The distance was not a failure of the system. It was the system's design.
The alternate history form allowed me to see this more clearly, I think, because it freed me from the obligation to document actual historical events. I could ask the structural question without getting lost in specific history. How does a bureaucracy transform atrocity into routine? How does an empire, any empire, make the intolerable administrative?
The ledgers also revealed something about the psychology of empire itself. When I studied the records of the real transatlantic trade, I noticed something peculiar: the numbers were often wrong. Not catastrophically wrong, but systematically off. Mortality rates that did not quite add up. Cargo that did not quite match the manifest. Insurance claims that slightly exceeded the declared value.
These were not wild discrepancies. They were small enough that they could be explained away as clerical error, as the inevitable friction of commerce. But they suggested something darker: the records were not primarily instruments of accuracy. They were instruments of deniability.
If a ship lost twenty people more than the insurance covered, the ledger could record it as normal wastage, as acceptable loss. If the numbers did not match, well, these things happened. The ledger protected the official from scrutiny precisely because it appeared to be rigorous. It looked like accounting. It sounded like accounting. But it was organised to conceal as much as to reveal.
In Trevannock, I wanted the alternate history to make this visible. The Adunbi Imperium's ledgers would face the same structural temptation: to record only what could be defended, to categorise in ways that diffused responsibility, to maintain the appearance of orderly commerce while the substance was slavery.
But the alternate history form does something else that proved crucial to my novel. It forces the reader to confront their own assumptions about power and technology and civilisation. We often imagine that advanced technology, sophisticated administration, educated elites somehow prevent atrocity. The ledgers argue otherwise. They suggest that sophistication is part of the mechanism. The better the bureaucracy, the more complete the distance can be. The more professional the record-keeping, the easier it becomes to regard human suffering as an operational cost.
This is not a comfortable thought, and it should not be a comfortable thought. The alternate history novel in Trevannock is designed to make the reader uncomfortable by showing a civilised, educated, administratively sophisticated power engaged in the same moral horror that European empires perpetrated. It is meant to ask: what makes you think it could not happen this way? What makes you think it could not happen again?
The ledgers taught me that the moral distance is not natural. It is built. It is built deliberately, through language, through categories, through systems of record-keeping that seem neutral and technical but carry moral weight. To write an alternate history novel that engages with this insight is to ask the reader to see the mechanism from the inside and to recognise it.
This is what I think matters about Trevannock, the alternate history I have written: it does not simply reverse historical positions. It interrogates the machinery of historical injustice. It shows that the machinery is transferable. And it forces the reader to recognise that bureaucratic distance is not a natural feature of human nature. It is a choice.
