The Mysterious Case of the Alperton Angels is Hallett’s third (substantial) novel to be published in the last two years, following 2021’s The Appeal, and 2022’s The Twyford Code. A fourth novel is already in the works. She is a busy writer!

The distinctive feature of all three novels is their format – they are modern versions of epistolary novels in which the narrative is told not by a narrator but through texts, WhatsApp messages, diary notes and in the case of Alperton a host of other primary sources, including extracts from a screenplay and two novels. This can make the narrative quite fragmented – there is no guiding consciousness to explain what is going on, the reader has to do a lot more of the work – but it is refreshingly different, and allows multiple voices and perspectives to be heard, as well as telling the story in lots of different ways. Together they tell the contemporary story of the eponymous Alperton Angels, a millennial cult that ended in a bloodbath eighteen years earlier. A baby that survived the killings is due to come of age, and Amanda Bailey, a crime writer, is commissioned to write a book about the case. The book is part of a crime series re-examining previous murders, and there are lots of references to real-life cases (Fred West etc). Her editor impresses on her that the key to making the book a success is finding and interviewing the rescued baby. And so it begins.
It quickly becomes apparent that there is more to the ‘mysterious case’ than originally appears. Some basic information about the three – or is it four? – deaths is missing. What appears to be a very well known and researched case melts away on closer examination, and none of the key witnesses can be found or are willing to talk. Alarmingly people Amanda tries to interview start to die off in unexplained circumstances. A fellow crime writer, Oliver Menzies, is also working on the story, and when their investigations overlap their publishers suggest they work together, trying to find fresh perspectives on the case. The novel’s approach to narration means information is slowly eked out and there’s limited reflection by the characters. Amanda’s transcription assistant, Ellie, provides a useful sounding board for her to bounce ideas off, but her relationship with Oliver is constrained by more than professional competitiveness – they have a history dating back to when they first entered the profession.
I had some reservations about Hallett’s earlier novels – yes, they were satisfyingly easy reads in which the pages kept turning quite briskly, but the mystery elements of the stories simply weren’t strong enough. The outcome of the various puzzles often depended on people behaving irrationally and sometimes just didn’t add up. With this novel at first it looked as if using a crime where irrational behaviour was a fundamental part of the case might have resolved some of these issues – if ever a participant did something unbelievable or bizarre it could be written off as symptomatic of the power of the cult. And Amanda seems very professional in her approach to her investigation – she has a sensible and very systematic working pattern which is set out clearly for the reader. She also has extensive contacts in the crime world (police and social services in particular) and is prepared to bend a few rules in the interests of getting the story. Oliver on the other hand is less impressive and acts as a drag on the investigation.
But suspension of disbelief can only get you so far. And so will being spoiler-free. So from this point in this review expect spoilers and stop reading if you haven’t yet read The Mysterious Case and intend to do so.
Firstly, I wasn’t convinced at all that Oliver would become a believer in the arrival on earth of the antichrist on the basis of a fifteen minute interview with the charismatic cult-leader, who we are told is just a common everyday kidnapper. Amanda impersonates a friendly spiritual adviser who leads Oliver further down the path but it’s still a long way before you decide to kill a minor royal on the off-chance they are the daughter of Satan. This was just one of many comically implausible features of the plot. Amanda’s decision to rush down to try and stop him (rather than say just phoning the police) made no sense at all. And while her investigation is presented as being very thorough there are some sources she ignores – the autopsies of the bodies or the transcripts of the trial proceedings for example, where the number of victims would be easily resolved and original witness evidence would be recorded. We are also invited to believe that not only would the police beat to death a suspect who had been seen walking through the front door of the local police station that evening, but they would then opportunistically add the body to the cult suicide crime scene (which incidentally wasn’t a cult crime scene at all, but the assassination of some underworld kidnappers) as a convenient way of disposing of it. That just makes no sense whatsoever – a beaten body looks very different from someone shot and ritualistically disfigured. And if that wasn’t unbelievable enough we are invited to believe that this was all witnessed by an American crime writer, over in the UK for research, who is allowed to watch the body being dumped and arranged at the crime scene and then just waved on his way back to the USA, never to mention what he saw again, despite it being the kind of thing a crime writer might actually, you know, write about. This is all just plain nonsense. Crime novels can have some improbabilities, granted, the untraceable poisons and so on, but this was way too much to ask.
Which is so disappointing, because the central idea here – revisiting a historic crime investigation, finding a new perspective and working out what has happened to the survivors – is great. And there have been suicide cults in the recent past that were led by charismatic charlatans. So the premise could have worked, and the narrative structure could have papered over some of the cracks and improbabilities. But never to this extent, at least not for me. Such a waste.
