Long term fan of Erskine’s writing here and this book is an absolute treat. A murder mystery grounded in science that takes you on a journey of surprising twists and turns until you reach the only conclusion possible (in hindsight). Fabulous read.

This is a hard book to classify. It is one of the few books that I did not like at first, but when I came back to it with a fresh mind and renewed interest, I found it an intriguing read.
The main reason for my initial reaction was the same reason I was intrigued later, another rare occurrence. Each chapter begins with the history in some related form or fashion of the Phosphate industry, circling back to the factory in Scotland.
The story begins with the finding of the skeleton at the location of an old Phosphate factory. In order to identify the possible identity of the unknown victim, an old foreman is brought to the police. From that point each chapter talks about one item found at the location, starting with one aspect of Phosphate that I am sure hardly any average person is aware of. It is in part a non-fiction book drawn from the author's experience, partly a homage to the profession and only a very minor part of it is about the 'mystery' itself.
The people introduced to us were quite different, each suffering a different type of issue. The non-fiction part of it was quite engrossing once I got into the groove of the narrative. The other part is not necessarily bad, but I would not have liked the book without all the facts I learnt (and some promptly forgotten) along the way.
The author's writing was good and what we got was exactly what was presented by the blurb and the overall look of the book.
I am not sure of the audience to recommend this book to, but I think anyone who looks at the blurb and the book and finds a spark of interest should definitely give it a go.
I read this as an ARC, thanks to NetGalley and the publishers, but the review is entirely based on my own reading experience.

Cleverly Plotted…
A factory demolition exposes a mummified corpse encased in phosphate rock. Ten clues to the identity surrounds it. Can the Chemical Detective crack this case? Wholly original, cleverly plotted and immersive mystery laced with humour and with a delightful protagonist and a deftly drawn cast of characters.

"The demolition crew found the body."

This is how Erskine's novel starts. A body was found in the ruins of what used to be the fertiliser plant in Leith. A body that was encased in phosphate rocks. Ten items are arranged on the desk in front of the body. And those ten items eventually help the former foreman John Gibson and the police to narrow down the time of death and the identity of the person.

I really enjoyed this mystery. It was full of lighthearted "nerdy-ness": some of the chemicals used in the process of making fertilisers are explained in an entertaining and not too scientific way. Erskine further has first hand experience having worked at the fertiliser plant herself, which gave her lots of material for the story's characters and their anecdotes.

It reminded me of one of those GAD whodunit that devilishly complex and you have no hope of guessing the solution because the author was very clever in plotting the story.
It's a great mystery and it's an interesting way to learn some science as the author is a talented storyteller and a good popularizer.
A gripping and fascinating story that kept me turning pages and trying to guess.
It's the first book I read by this author and won't surely be the last.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine

During the demolition of a factory, a shocking discovery is made: a mummified corpse encased in a carapace of hardened dust – phosphate rock – surrounded by ten objects that provide tantalising clues as to its identity. Phosphate Rocks: A Death in Ten Objects unravels the mystery using a mix of real-life anecdote, scientific explanation, and a touch of fiction, woven together to create a vivid account of the life and decline of a factory over five decades. Highly recommended.

Phosphate Rocks was a very intriguing read. Part fiction, part science lesson, I found it to be an enjoyable read. It’s relatively short, and structured in such a way that it’s easy to pick it up and read a bit when you have the time.

This is an incredibly quirky read that from the beginning really held my interest and had me really thinking and taking in the science.

It’s almost a book of 3 parts, you have the factory where it’s set and the intricacies and inner workings and various jolly, weird and wonder workers with nick names to suit,

Then there is the crime, and police investigation or interviews really,

Then the science,

As the book wears on though I think it became a little lost on me as the science and almost textbook feel becomes more apparent and the interesting crime very much takes a back seat.

I appreciate the very different premise, the setting, the way the book is set out and for a reader rather more literate than myself I can imagine this will go down a storm,

The extraordinary, smart and knowledgeable Fiona Erskine changes direction from her wonderful Chemical Detective series to write this mystery, a blend of fact and fiction, whilst simultaneously providing a glimpse into the bygone world of Scottish Agricultural Industries, an old Leith fertiliser factory, run with an iron fist intertwined with a compassionate understanding of his workers by John Gibson, the shift manager. Erskine provides a fascinatingly detailed insight into the chemicals and processes used, and if you are wondering about the source of her information, she once worked at the factory, mentored by Gibson in reality, this is a fictionalised account of their adventures. She describes this novel as 'Inspired by Primo Levi, in the style of Dan Brown, this is a portrait of a factory in all its complex, glorious, interconnected, messy entirety. A hymn to the forgotten, the unknown, the misunderstood, the story of a factory in decline and some of the fine people taken down with it.'

Driving the engine of this novel is the discovery of a body, a macabre tableau, discovered in phosphate rock at the abandoned factory being demolished. The dead victim is seated at a table on which are ten objects, clues and red herrings as to his identity. Leading the police investigation is DI Rose Irvine, assisting her with her inquiries is Gibson, who recognises every item on the table and the stories and people attached to them. The items include a ebony elephant with a strong whiff of sulphur, an Aberdeen key ring, a Barbie Doll with a rather exclusive and expensive dress, an air horn, whisky bottle, a broken pair of sunglasses, a brass washer, and an oil can (Aladdin's lamp). Gibson himself does not escape coming under the suspicious eye of Irvine, but the surprising and despairing answer to the mystery is arrived at by him.

Obviously the technical knowledge of this novel may not appeal to some readers, but books that carry a holistic knowledge of chemical elements, the Scottish fertiliser industry, and the community of skilled and memorable characters that worked at the factory, delivered through the form of an engaging mystery are rare indeed. What made this an unmissable read for me were the guys working on site, so often written off and misunderstood as unskilled by those above them, but were actually the beating heart of the company, with the kind of specialist knowledge and experience that is essential and valuable. One such guy that made an impression on me was the profoundly deaf, hard working and reliable Becksy, more trusted than many other workers. If you are looking for something different to read, wanting to learn about the field of applied chemistry and the old fertiliser industry in Leith and its people, then I cannot recommend this unique mystery highly enough. Many thanks to Sandstone Press for an ARC.

I would like to thank Netgalley and Sandstone Press for an advance copy of Phosphate Rocks, a stand-alone novel set in Edinburgh.

When an old phosphate factory is being demolished a body is found encased in phosphate and surrounded by ten objects. DI Rose Irvine turns to former shift supervisor at the plant, John Gibson for help in identifying it.

Firstly I would like to state that my rating of the novel is purely due to my personal preference in reading matter and not to do with quality.

I admire the idiosyncratic format of the novel as it is most unusual and adventurous. I also like the free flowing tone and writing and I imagine it would make an excellent audio book as it sounds exactly like the author is speaking. It is also quite compulsive in its plotting, as I soon felt a burning desire to know who the belongs to, how it got there and why.

The ten objects found with the body form the basis for John Gibson to narrate a tale from his time working in the plant about a different character. They’re interesting because they go back to the 80s and 90s when life was very different. I forgot how different until I read the novel, and the author does a sterling job of reminding me of those times and my own job in a factory. It’s very realistic. These stories, however, are only one third of each section as the other thirds cover how a section of the plant one works and a brief history of the chemicals used in that section. As someone who walked out of her last science lesson 55 years ago and never looked back these held zero interest and even less understanding. It’s simply not my thing and the small snippets of history included only relieved the tedium slightly.

I picked this novel as it is listed as a crime novel and the Scottish setting was a bonus. Having read it I can’t say that I see it as a crime novel, more of a jaunt through the past from a chemical engineering point of view. It’s not my kind of thing - too much science and not enough investigating - but I think it will appeal to more technically minded individuals. If the content were different I would be raving about this novel, due to the tone, characterisation and writing style.

It doesn’t matter what you may think this book is about. If you read the brief, teasing blurb above that’s only going to scratch the surface of the story in Phosphate Rocks.

As I read the book I tweeted a few times that I had no idea how I was going to review it. That hasn’t changed, I am not sure how to succinctly articulate the utter pleasure I experienced reading Phosphate Rocks. Or the anguish, the horror, the fascination or the fun. This book had it all and, when it was done, I wasn’t. I wanted more. I wanted to keep reading about these remarkable overlooked heroes of their craft.

So what’s it about?

Well there’s a dead body in an old chemical plant in Leith (Edinburgh). The site is no longer active but before everything closed down it seems, somehow, a huge shroud of phosphate rock encased a work hut. Inside that hut was a dead body sat at a table. Laid out on the table in front of the corpse were ten objects which the police hope John Gibson, former shift manager at the site, can use to identify the deceased.

Sitting in a police station, years after his plant had closed down, John identifies each of the ten objects and tells Detective Inspector Rose Irvine the story behind each item. With each passing object the reader gets to know more about the men that worked the site, the work they undertook and how chemicals and materials from around the world would pass under the nose of these Edinburgh workers.

Also filling in the reader with background information is author, Fiona Erskine, who gives each object a quirky and fascinating science lesson. You learn about chemicals, reactions, inventions and discoveries. Reading this book taught me how chemicals move around the world, how they need carefully stored and cared for and how it’s the plant workers that know best how to keep a busy chemical site ticking over – not the managers, chemists or owners. It may not sound like slipping chemistry learning into a crime story could be fun or engaging but it is utterly absorbing (though Fiona will likely correct me on what absorption actually is).

The stories behind each of the objects are wonderful. Although this book is a work of fiction I am 100% convinced that many (if not all) of the stories are entirely anecdotal and based on actual events from the site. Why tie a long string around the neck of a whisky bottle? Who had the best dressed Barbie Doll in Scotland? Why should you not hit a pipe with a hammer and is that an author cameo we see before us? If many events in the book are indeed based on actual events it may go a long way towards explaining why the book is so engaging. Nothing feels forced, overdone or over-exaggerated. The guys (and in the main it is guys) working on the site all feel utterly real and entirely plausible. I defy you not to warm to them.

The true hero of the piece is John Gibson. He is taken on a journey back through his working life and the stories he tells DI Irvine bring back memories of old colleagues – some more fondly remembered than others. John and DI Irvine are a charming pairing through the story too their conversations, some of which take place away from the police station when Irvine tracks him down to his favourite restaurant, are a cautious but intricate dance. Neither party is willing to overshare but both appear to crave more knowledge about the other.

Phosphate Rocks is a crime story. There is a dead body, there are clues to help the investigators determine his identity and there is a man helping police with their enquries at the police station. But Phosphate Rocks is so much more. It is a story of a life (John Gibson), of many lives, of a plant that no longer dominates its corner of Leith and of the men who for years kept that plant ticking over. Clever men, inventive men, hard men and men with secrets. But I felt Phosphate Rocks is also a love story. I read of a time now gone which is much missed, a love of science and method and process and of low paid staff performing dangerous and skilled work. An affection of the cameraderie, the respect for John Gibson and the responsibility he held for the staff on his shift. It’s funny then it’s tragic and I want you all to read this story too.

Phosphate Rocks, currently my book of the year. It will take something incredible to top this one.

I simply can't remember when was the last time I got so intellectually engaged with a murder mystery written in English!
Ms Erskine definitely rocked my day with her fiendishly plotted and scientifically intriguing whodunit evolving around the unexpected discovery of a skeleton embedded in phosphate rock and the various objects found with it by a demolition crew at the site of an abandoned chemical plant in the rather bleak industrial landscape of Leith. Who is it? How long has it been there? And could the various and rather innocuous objects surrounding it be made to yield any clue? Just one point is certain: that death occurred after 1950 and before the 1990s....
A head scratching puzzle that will be painstakingly brought to a stunning denouement with brio, definitely leaving more than a few readers totally gobsmacked! Finally this incredible novel is also a captivating look at the Scottish chemical industrial world and its working conditions during the second half of the 20th century! The ultimate chemistry lesson to be enjoyed without moderation!

Many thanks to Netgalley and Sandstone for the opportunity to read this wonderful novel prior to its release date

Fiona Erskine’s Chemical Detective series has put her in the top rank of modern thriller writers but her new book takes an intriguing step in a different literary direction. Phosphate Rocks is a beautifully written work that defies categorisation. It is a murder mystery that is also part memoir, part chemistry manual, and the unique fusion of styles will educate and entertain crime and literary fiction fans alike.

The story centres around a body found inside the bowels of a Scottish fertiliser factory which is bizarrely caked in phosphate rock. Beside the corpse, and also encased in a chemical carapace, are a selection of random objects which provide clues (and red herrings) to the identity of the victim and the manner of the death. A female detective investigates, with John, the wise but irascible retired foreman of the chemical plant, her main witness. The satisfying plot leads us to a cracking (literally) denouement, but the narrative also takes us on a spectacular journey through the lost landscape of British heavy industry. It is a landscape peopled by remarkable workers, both heroic and hilarious, and it is home to chemical processes that are jaw-dropping in their scale and their potential danger. A particularly hair-raising episode throws the author’s alter ego (Fiona) into a tricky chemical dilemma that leads to a serious industrial accident. The scientific insights of her experiences reveal how close Edinburgh might have sailed to the terrible fates of Bhopal or Beirut.

Phosphate Rocks concludes with a biographical survey of the great chemists of the past and the book is a fascinating, compellingly-told paean to the bold visions and intrepid workmanship of the people who turned chemistry into industry.
