Dorothy and
Tom are on a date to
The Proms. However, the performance of works by
Saint Hildegard of Bingen is interrupted when a mysterious monk tumbles to his death from the gallery. Dorothy subsequently reveals that she has seen a post on the
ePi forum to the effect that 'the monks were coming to claim what was rightfully theirs.' The user who posted this was called
SaintHildegard, who has since deactivated their account. Dorothy senses something in the air, but can't yet work out quite what, but wonders if it has something to do with the
Vavasor papers, which apparently
Isaac Vavasor and
Kevin Wilbraham have both been spotted chasing after in various parts of the world.
Dorothy suggests that the only person who can help them figure out what's going on is Margot Evercreech, the only person ever to have interviewed Isaac. So Dorothy and Tom go to visit her, where they are greeted by a shotgun-waving Margot and her alpacas, Dolores and Steven. They also find Benjamin Unsworth, who is now working for Margot as her archivist, having been fired by Helen Matheson. It turns out that Isaac was something of an expert on Hildegard of Bingenand that here was also something about monks in an archive if his that Margot previously acquired. However, this archive has gone missing, on a laptop that Margot was also messing around with cryptocurrencies on, including Tulpencoins. Dorothy puts two and two together and deduces that Margot's laptop has been stolen and taken to Channellia, where it sank along with the rest of the rig. She persuades Tom that he should retrieve it.
Tom goes to Burnham-on-Sea, where he encounters the diver Sven who will take him out to the submerged rig, five miles out, the next morning. In the Jolly Sailor that night, he also comes across the mysterious Jasper Bancroft, who gives him his card. The next morning, Sven takes Tom out to the submerged Channellia and he dives down to fetch Margot's laptop. On his way back to the surface, he is attacked by someone with a harpoon, who he fends off by hurling his weight belt at them. When he breaks surface, he finds that Sven has vanished. Unexpectedly, Bancroft shows up to rescue him, but he in turn is shot by the man with the harpoon. Tom manages to escape back to Burnham and finds that Sven has vanished, apparently gone fishing.
Tom goes back to London with Margot's laptop and he and Dorothy persuade her business partner Ali to retrieve the archive from it. This reveals that in the course of Isaac's research into Hildegard of Bingen, a person known only as S had brokered a meeting with a mysterious monk, who in turn had expressed a desire to meet Archie and Pye, as his order was interested in making use of their mathematical expertise, specifically in the area of fractals. However, the only thing that ultimately came out of this was work that would turn out to be useful in their subsequent relationship with the Belarusian mafia. S, meanwhile had disappeared off the face of the earth.
Having reached a dead end, Tom decides to go back to Burnham-on-Sea to find out why he was abandoned by Sven. On a tip-off, he heads over to the lighthouse where a trail of blood leads to Sven's body, wrapped in a monk's habit, hidden in the rough on Burnham golf course. Having reached yet another dead end, Tom remembers that he has Bancroft's business card, so he rings the number on it. Helen Matheson answers, but Tom fails to get any useful information out of her. Meanwhile, a helicopter lands and a group of monks leap out of it and retrieve Sven's body.
(More to come...)
