After reading his book on polio and his book on smallpox, I wasn’t quite sure what to make of Gareth Williams turning his hand to something like the Loch Ness Monster — but nonetheless, I knew he was a good writer and understands science and the importance of evidence. And Nessie is fascinating, of course; even if there is no Nessie (and I tend to think there isn’t) then it’s fascinating how people have believed there was a Nessie, and spent their whole lives searching for her. I needn’t have worried, anyway: Gareth Williams presents the evidence without much sign of being partial. He notes when people’s evidence was convincing or their testimony likely to be trustworthy, as well as noting when people carried out fakes.
It turns out to be exactly as fascinating as you’d expect, looking at all sorts of people who made or broke their reputations hunting for the monster. In the end, we have very little direct evidence pointing to the existence of a Nessie, so unsurprisingly the book looks at the human side of the drama, along with the sciences that, over time, people have brought to bear on the problem.
I’m sure some writers wouldn’t be able to make this interesting, but to me, Williams did. And if nothing else, he had me wanting to believe in Nessie, for all that he attempted to stay neutral himself (and I wouldn’t like to pin him down on either side of the debate for absolute certain, though I think a lot of people wish it could be true but don’t think it is).
