Tom Winscombe and Dorothy Chan were hoping for a quiet evening out listening to choral music by twelfth century Saint Hildegard of Bingen. Their plans get sent somewhat awry though by the death of robed monk, after falling from an upper gallery. They're soon off on a trail which leads them to a very strange religious order, and to Isaac Vavasor, custodian of the papers of his famous brothers, mathematical geniuses Archie and Pye. Somewhere along the way there are alpacas and pigs, a missing thesis to be retrieved from the bed of the Bristol Channel, an assassin with a harpoon gun, a secret mountain-top monastery to break in to, and people who'll do anything to stop Tom and Dorothy finding out whatever the monks are hiding.
This is the third of Tom and Dorothy's adventures, and really if you want to understand all about the exciting ground-breaking mathematical theories of the Vavasor twins, the applications they can have in the 'real' world, and the lengths people will go to to get their hands on a few equations, you're best to read The Truth About Archie and Pye, and A Question of Trust before embarking on this story. You could just plunge straight in though; you'll probably pick up the gist of things as events spiral out of control.
It doesn't really take a lot to get Dorothy involved in anything concerning the Vavasors, and where Dorothy goes Tom is often not so much just behind as being sent in front to do the dangerous stuff. Dorothy is definitely the brains, while Tom provides the, well, 'muscle' doesn't seem quite the right word, but something close. I've lost count of the ways he's avoided a bizarre death so far, and this time is no different.
Throughout lockdown, I've struggled to find books that hold my interest. Maybe because this is just not trying to reflect the 'real world, it did. It's maybe not an overly plausible story-line, but it's a compelling read and a lot of fun.
Tom is never going challenge James Bond at espionage, but he's always willing to try.
