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. Tom notices a mysterious symbol on the monks' robes.
Back in London, Tom shows a sketch of the symbol to Dorothy, but it means nothing to her. Instead, she and Tom go off to see Margot again. However, when they get there, Margot's house has been completely emptied, Alpacas and all. Their taxi driver mentions that she was visited by some monks recently, possibly from Greece, with a name that sounds like the Order of the Roman something. When they get back to the office, Dorothy decides they need to seek advice from an expert on monks, so she sends Tom to the Roman Catholic Church of St Wilgefortis the Divine where he meets Father Donal. When he starts to describe the monks, however, Father Donal becomes terrified and orders Tom to leave, go home and forget everything about them.
Later that night, Dorothy and Tom try to break into the Presbytery to steal Father Donal's book of monks, but instead they find Father Donal dead, having eaten one of the pages of the book before committing suicide. The next evening, they go round to Patrice's flat again, where it turns out that she is cooking Romanesco cauliflower for their evening meal, and Tom realises that this is the design on the monks' robes. Patrice explains that this is an example of a fractal pattern, and indeed it seems that, on searching for information on the Order of the Romanesco, they are also known as the Fractal Monks. Dorothy asks for information on the Vavasorology.com forum, but the thread gets immediately deleted and she is barred. eventually, they manage to find a notice about a forthcoming funeral of Brother Anselm, a member of the order, at North Greaseby Priory.
Tom goes to North Greaseby and sneaks his way into the Priory in time for the funeral, disguising himself in monks' robes. It turns out that the person being buried is in fact Sven the diver. Tom also catches a glimpse of someone unexpected, also disguised as a monk - Helen Matheson. However, any further investigation is cut short when Tom is overcome by chloroform and kidnapped by Margot and Benjamin, who are also there, undertaking their own investigation. Margot is suspicious of Tom and thinks he is involved with the monks somehow.
Margot, Benjamin and the two alpacas are now hiding out on a farm. Tom escapes by getting Dolores to nibble through the rope tying his hands together, and he escapes in Margot's van, taking the two alpacas with him. Tom leaves the alpacas in the care of his father's friend Mad Dog McFish and abandons the van, after removing from it a card key for the Norwich branch of STUFF YOUR STUFF, a self-storage facility. They locate Margot's lock-up and extract the most interesting-looking boxes of her archives. However, at this point, they are trapped by a pair of monks. They manage to escape, noting on exiting the facility that the security guard at the entrance has had his throat slit.
On the way back to London, Tom texts Ali to warn her that she and Patrice may be in danger, and All responds by saying that Patrice's flat has already been ransacked. They go straight there, but the disc drive from Margot's laptop hasn't been touched, although Patrice's papers are in a completely mess.
