One of my resolutions for 2025 was to read more non-fiction books, so I’m ashamed to say this is only my second one this year. Oh, well – I still have more than seven months to add a few more to that total. I would also like to widen the range of topics I normally choose to read about and try something different, but for now, with That Dark Spring, I have stayed within one of my usual areas for non-fiction – true crime.
The crime in question is the murder – or could it be suicide? – of Olive Branson, an Englishwoman in her forties found dead at her farmhouse in a village in Provence. This happens in April 1929, when she is discovered submerged in a water tank outside the house, a bullet wound between her eyes and a revolver nearby. The local policeman and doctor conclude that Olive shot herself, but not everyone is happy with this verdict. Back in England, Olive’s wealthy, influential cousin demands that the case be reopened, so one of France’s top detectives, Alexandre Guibbal, is summoned from Marseille to investigate.
It’s an intriguing mystery! Could Olive really have lifted the heavy cistern lid, lowered herself in and shot herself – with her left hand, despite evidence suggesting that she was right-handed? Guibbal doesn’t think so and quickly turns his attentions to François Pinet, believed to be a lover of Olive’s for whom she had changed her will to leave him the Monte Carlo Hotel, which she had recently purchased. As evidence mounts up against Pinet, he insists that he is innocent and is defended by many of the villagers who are keen to support ‘one of their own’. There’s eventually a trial, but even then a lot of questions are left unanswered. Susannah Stapleton can’t – and doesn’t – give us those answers, leaving us to draw our own conclusions and try to decide what really happened.
I enjoyed That Dark Spring overall, although it took me a while to get into it due to the amount of background information provided in the first half of the book: a history of the village of Les Baux and the Baussenc people; an account of Olive’s early life and her career as an artist; detailed descriptions of the two rival hotels in Les Baux; and a long and (as far as I could tell) irrelevant biography of the poet Frédéric Mistral. Some padding is to be expected in books of this type, of course, but I found that I only became fully engaged with the story when it returned to the central crime. There are some points that wouldn’t be out of place in a detective novel, such as where Guibbal consults an astronomer in an attempt to decide exactly when darkness fell on the night of the crime or where Pinet tries to use the sighting of a car as an alibi and becomes entangled in his own lies.
It’s frustrating that we still don’t know the truth behind Olive’s death and probably never will. If Pinet was innocent and we assume that suicide was unlikely, that must mean someone else got away with murder – but who was it? Stapleton doesn’t really steer us into one way of thinking or another; she just provides the facts and some possible theories for us to consider. She suggests that the police may have been so determined just to pin the blame on somebody that they ignored or failed to collect important evidence, leaving Pinet’s fate up to the lawyers and the jury.
Stapleton has drawn on a number of primary sources and includes excerpts from Olive Branson’s diaries and letters throughout the text, giving it a more personal touch. There are also notes at the end, a bibliography and a list of Olive’s exhibited artworks. I had never heard of Olive until now, so it’s good to have learned a little bit about her. I’ll have to go back and read Susannah Stapleton’s other book – The Adventures of Maud West, Lady Detective.
