Fred Vargas writes a beguiling and often unusual mystery novel. Her series featuring Commissaire Adamsberg and the Serious Crimes Bureau is immensely entertaining for the weird and wonderful storylines and oddball criminals – usually serial killers of some kind with motives beyond the everyday. The latest book – This Poison Will Remain – involves a type of murder no one believes to be anything other blood-poisoning following a spider bite. In Nimes three old men suffer septicaemia and die, but they were old, right? Could happen to anyone, right?

Jean Baptiste Adamsberg, with his nose for the uncanny, thinks otherwise. But he’s going to have a tough time convincing his team to agree with him. Particularly Commandant Danglard, his second in command and former friend. Danglard, in his impeccable English tailoring has become a formidable opponent and with his gift with words and sharp intellect, he soon has the others thinking Adamsberg has lost the plot. This is a new Danglard. In previous books we see him sipping wine on the job and bemoaning his problematic home-life.
You soon realise that this is not your usual police station. There’s Mercadet whose narcolepsy interrupts his police work daily, so he has a cushiony corner in a quiet office where he can catnap. Maternal Helene Froissy keeps a cupboardful of snacks at the ready and helps Adamsberg look after a family of blackbirds who have nested in the courtyard. Amazonian Violette Retancourt is ‘worth ten men’ and is devoted to Snowball the cat who sleeps on top of the photocopier no one uses but is always on to keep it warm. Voisenet would rather be an ichthyologist and stinks out the office with the head of a moray eel he plans to study. Veyrenc hails from the same corner of the Pyrenees as Adamsberg. With his black-and-ginger striped hair, the result of bullies trying to scalp him as a boy, he bursts into clunky Alexandrine verse at every opportunity.
It is Veyrenc whom Adamsberg first turns to for help in solving the mystery of the spider bites, secretly at first. It emerges that two of the victims lived at the same orphanage and were part of a gang who tormented the other boys, hiding recluse spiders in their clothing. In those days before readily available antibiotics, some of their victims endured terrible injuries. If someone was out for revenge, it would be fitting to kill them with spider venom from the same kind of spider, but such spiders are rare and you would need dozens to produce enough poison. And how on earth would you milk the spider venom anyway?
It seems an impossible puzzle, so it isn’t surprising Adamsberg and Veyrenc adjourn to a nearby café, called La Garbure, after the traditional cabbage soup from the Pyrenees, to discuss the case. This is something else I love about the series. Reminiscent of novels by Simenon, Fred Vargas conjures up Paris through Adamsberg’s walks by the Seine, and scenes set in cafés and restaurants. Veyrenc has a bit of thing for La Garbure’s proprietress and the two send each other glances across the room without quite catching each other’s eye.
Like the best crime fiction, the story is very much character driven, but Vargas has plenty of surprises in store for the reader to keep you turning the pages. Adamsberg has the challenge not only of solving the most perplexing of crimes, one that will take him back to the memory of a terrible event from his childhood, but he must also win back the loyalty of his team. Themes around child abuse, mental illness, isolation and the history of religious hermits give the story plenty of depth.
This Poison Will Remain is an excellent read, with a superb English translation that maintains the spirit of the author’s unique, lively and very French style. A four star read from me.
