Necessary Evil by Ian Tregillis

Necessary Evil Ian Tregillis

To get any value out of this concluding volume in the Milkweed Triptych, you should have read the first two books in order. I can say without fear of contradiction you will not understand a lot of what happens without knowing what has gone before. Ironically, the same applies to this review. I’m not going to repeat the discussions set out in the first two reviews. I’m going to focus on this book.

In Bitter Seeds, the first book by Ian Tregillis, the question is what the precog has foreseen. The Coldest War answers this question and tell us what she proposes to do about it. This leaves us with Necessary Evil (Tor, 2013) which allows us to watch how her grand design works out. From the outset, we’ve been considering whether any of these alternate timelines is deterministic. The presentation has suggested only one person has free will. Given the breadth and depth of her ability to foresee the future and pick which timeline to follow, the precog has been charting her path through the decades. In a multiverse, every decision point branches, casting off alternate realities but, up to this point, everything has worked out exactly as she has foreseen. Indeed, what she’s achieved is breathtaking. Given the scale of what she wanted to avoid, she’s had to work backwards from the one route to salvation and examine all the decision points to see how she can get there. In so doing, she’s been reviewing a potentially infinite number of alternate histories, seeking out the key moments and identifying the people she needs to influence into acting or not acting. Of course, I could invert this and say her fate was set when she was born. She was always going to arrive at the point representing the end of book two. She merely had the illusion of free will.

This would suggest others might have free will or that no-one ever has free will. But if that were the case, the very idea of a multiverse would be a paradox. If no-one ever has free will, there can be no alternate timelines. There could only be the one timeline that everyone is predestined to follow. This leads me to major problems with the plot. If this book deals with an alternate history timeline, the two people who are sent to this 1940 are from outside this timeline’s cause and effect. What has happened to them in their own timeline remains because it has already happened. It cannot be undone when the cause does not occur in the new timeline. Yet Ian Tregillis wants to play fast and loose with this issue. In this book’s timeline, the man who should survive to send them back in 1963 dies in 1941, yet the older Marsh remains in this timeline. But when the younger Marsh does not suffer the leg injury, the travelling Marsh’s leg is cured. You think that’s bad? Well here comes the nail in the coffin. In this timeline, there are two versions of Marsh but only one precog. If we have an older and a younger Marsh, why do we only have one young precog? What happened to the older version of the precog when being transported back? It’s this lack of attention to the logic of the plot that completely spoils the effect.

So putting that to one side, what are the consequences when the precog is to some extent able to reset the clock? In theory, this new timeline should unfold according to the master plan. The younger version will guide events to avoid the catastrophe she has foreseen in all the other timelines. This timeline will survive. Except, of course, there’s one small change. Up to this point, she’s been the only one with an overview of time. Now there’s a second person and he understands both the strengths and weaknesses of the precog. So he can share the precog’s desire to avoid the looming catastrophe, but not be prepared to pay the same price to achieve it. More importantly he can also work backwards and understand what would need to happen to ensure the safety of those he cares about. Ah, so now we come to the heart of the Triptych. From page one of Bitter Seeds, we’ve been watching how individuals have reacted when they learn the price to pay to get the results they want. At a national level, governments at war cannot be concerned about the individual. They are fighting for the majority of their citizens and if that means sacrificing the few, that’s a price worth paying. At the other end of the scale, the individual wants to survive but may be prepared to sacrifice him or herself if the price is right. So a loving father might sacrifice himself to save his child, a spy threatened with capture might commit suicide to avoid betraying his country.

Of course, this is talking about sacrifice in physical terms but individuals may also sacrifice their principles if that’s necessary to save themselves or others. Hence, the title of the book. History shows us that some people have fought with honour, maintaining their personal integrity and protecting the reputation of their country for fair play. History also shows how often those who play fair are beaten by those who ignore the rules of chivalry and play to win regardless of the cost. It’s been a sad theme to see how often the honest are surprised by the extent of the dishonesty around them and how easily that dishonesty can strike them down. So an individual who recognises the full extent of all the risks may well be put to the choice. When there are dishonourable options, will the decider pick the least evil or do what’s necessary to win?

You’ll have to read the book to see how it works out but, as you might expect, it’s not clear cut. When we all know exactly what price has to be paid for ultimate success, there’s a certain degree of irony in how the final element of the price is collected. Perhaps that’s how fate actually works. If there’s a sine qua non and several people are aware of it, it doesn’t matter who fulfills the condition so long as the precondition is met, i.e. the necessary evil occurs.

This leaves me with an issue I referred to in the first review but it grows significantly worse in this book. Let’s start with the practicality of life described as Britain in 1940. Early on, our hero from the future needs some local cash so he gets on a bus with some future bank notes in his wallet. The idea that a bus conductor could change a five pound note is absurd. Ignoring the physical difference in the size and colour of the future note which would be spotted immediately, the average annual pay in the UK in 1940 was about £200. So even on the busiest routes, no conductor would collect and keep more than £5 in loose change. That’s 1,200 pennies except the average bus fare around that time was a hapenny (i.e. £5 = 2,800 coins). So the conductor would be weighed down with farthings and hapennies, perhaps some thrupenny bits and sixpences, and the occasional shilling. During quiet times, the conductors used to bag the excess loose coinage and either lock it in a cabinet in the stairwell or give it to the driver for safe keeping in the front cab. Even if this conductor had enough to give change for more than one’s weeks pay, consider how long it would take to count out more than one thousand coins and how much they would weigh. This is symptomatic of a cavalier attitude towards all things British, particularly its language. I know and appreciate that this is a book written by an American for the American market, but it’s aggravating that the vocabulary and vernacular attributed to British and German characters comes out as modern American English. Scattering one or two British colloquialisms does not make this book even remotely realistic. Oh but wait. This is fiction so it doesn’t have to be credible.

I was really looking forward to reading Necessary Evil but the reality has proved a major letdown. Once you set out to write a time travel or multiverse story, there are rules to be followed. This happened in the construction of the first two books. It’s such a shame the rules were mostly thrown away in this concluding volume. If I’d known it was going to be this bad, I would never have paid for my own copy.

    Actually, Marsh was the only one, who traveled to alternate universe, old precog died together with the world.
    It is really hilarious:
    “Once you set out to write a time travel or multiverse story, there are rules to be followed.”
    Maybe you should stay away from fantasy😉

      If she is to be taken as original to this alternate reality, how does she know what happened in a different reality?

        she has seen all future timelines including the one in “The coldest war”.

        So you’re saying that, in all realities, she can foresee the population in all worlds including her in all her iterations will die at some point in the future. However, if she follows a particular sequence of events in World A, everyone in that world save Marsh will die. Marsh will be transferred to World B and that will save her in World B. If she is rational, she should follow this plan in half the worlds in which she exists. If this plan is so powerful, the transfer of Marsh from half the alternate worlds designated World A should save her in all the worlds designated World B. I’m probably being foolish here, but I don’t understand why the plan cannot be replicated across multiple alternate worlds.

        And I also have problems in understanding why she does not foresee the loss of her power caused by the presence of the two versions of Marsh. This is a not insignificant downside to the plan and would more than justify multiple experiments to arrive at an alternate World B still having the power of foresight.
