A great book about a fascinating historical period and one of the forefathers of forensic science.
Fatal Evidence: Professor Alfred Swaine Taylor & the Dawn of Forensic Science - Helen Barrell

Thanks to Pen & Sword, particularly to Alex, for offering me a copy of this book that I freely chose to review.

As a doctor, a writer, and an avid reader of crime fiction (and spectator of crime films and TV series) when  I read the description of this book I knew I had to keep on reading. Although my studies in Criminology included a basic history of the discipline, this book offers a very detailed look into one of the main figures in the early times of forensic science, Professor Alfred Swaine Taylor. The author, Helen Barrell, uses her expertise in history and genealogy to research his biography and investigate the legacy of this fascinating man. As she states:

This is both Taylor’s biography and the story of forensic science’s development in nineteenth-century England; the two are entwined. There are stomachs in jars, a skeleton in a carpet bag, doctors gone bad, bloodstains on floorboards, and an explosion that nearly destroyed two towns. This is the true tale of Alfred Swaine Taylor and his fatal evidence.

I found the book riveting. Not only the biographical details (and, as a doctor, I was intrigued by his studies, and by how complicated it was to study Medicine at the time. In fact, becoming a surgeon and becoming a medical doctor involved a very different process in the early XIX century, and although now the degree combines both, their origins were completely separate), but, especially, the in-depth study of his close involvement with forensic science, his passion for the subject, and his total dedication to ensure that forensic evidence was rigorous and given the importance it deserved in criminal trials. He produced books on the subject that were updated and continued to be published well into the XX Century and his expertise as a chemist, photographer, and defender of public health made him a well-known and respected figure. On the other hand, he was not the easiest of men, he did not tolerate fools gladly, he was a staunch supporter of unpopular measures (banning certain products containing arsenic, for instance, or introducing a register of the purchase of poisons), and he held grudges that found their way into his writing, and perhaps made him not receive the recognition others did (he was never knighted, while some of his peers were).

The book follows Taylor’s life in chronological order, and although it delves more into his professional life (the cases he gave evidence in, other cases of the period he advised on, his teaching, his books), it also talks about his wife, and how she was fundamental to his books, as she helped him organize and compile the cases, about the children they lost, his friendships and collaborations… We get a good sense of the person behind the scientist, but it is clear that he was a man dedicated to his work, and it is not so easy to differentiate the public from the personal figure.

The book is written in an engaging way, it flows well, and the author provides enough detail about the cases to get us interested, making us experience the tension and the controversies of the trials, without becoming bogged down in technicalities. And, despite her historical rigour, the author’s observations showed subtle hints of humour on occasions.

The chronology and all the cases he worked on help give us a very good idea of what crime was like in the period. Having recently read some other historical books (many published by Pen & Sword as well) about the era, it manages to create a great sense of how easy it was to buy poison, how difficult it was to detect crime (even confirming if a red stain was blood was very complicated), and how dangerous everyday life could be (wallpaper contained colours filled with arsenic). Some of the cases are still remembered to this day, but Helen Barrell offers us a new perspective on them. This book would be a great addition to the library of anybody interested in the history of the period, especially the history of crime detecting and poisons, and also to that of writers of crime novels who want to know more about forensic science and its origins.

The last chapter includes a summary of some of the ways Taylor influenced crime writers, including Conan Doyle and Dorothy L. Sayers (who either created characters based on him or used his books as reference). I am sure many writers will feel inspired anew by this book, especially those who write historical crime fiction. There is also a detailed bibliography and notes that would help anybody interested in finding more information about any of the cases.

As the author writes in her conclusion:

Alfred Swayne Taylor is one of the ancestors of modern forensic science: he is part of its very DNA.

A great book, of interest to anybody fascinated by crime detecting and its history, to readers of the history of the period, and to writers (and readers) who love crime historical fiction. A fascinating historical figure and a well-researched and engaging book that gives him some the credit he deserves.

The Last Alchemist in Paris by Lars Öhrström
The Last Alchemist in Paris: & Other Curious Tales from Chemistry - Lars Ohrstrom

If you've been following my updates, you're probably aware that I find this book to be a bit "scattered". It's not disorganized; it's just that it isn't always immediately apparent where the author is going with a particular story, or how he's going to tie the chemistry into the story, especially if it's a historical anecdote that you had never heard of before. The whole book is a series of stories where the author ties in chemistry to historical anecdotes. He's also not afraid to break out chemical equations and discuss how the three-dimensional shape impacts the reactions that take place.


Several of the anecdotes are quite interesting (a few not so much), and I really liked the author's sense of humour. He makes references to The Hitchhiker's Guide to the Galaxy and Agatha Christie, among others. I'd gladly read another book by the author; I'd just hope it to be a little more focused.


An example (from page 220) that I feel like quoting:

Thermodynamics, especially chemical thermodynamics, is a fascinating subject, but many students find it difficult. I think part of the problem is that it starts off by stating the obvious in great mathematical detail, which makes everyone fall asleep, and when they wake up again the lecturer is well into partial derivatives with symbols such as S, G, and µ, and it is very difficult to catch up.


Make of that what you will; your mileage may vary. :)

The Story:

In the second installment of Katy and Martin we get to know Martin better and we also get our heart broken. Yes, the inevitable break up happens and I cried my eyes out right along with Katy. The story gets so heartbreaking but I was still compelled to finish.

The Random Thoughts:

-Katy over thinks everything! And it’s beginning to get a bit annoying. (says the overthinker)

Attraction: Elements of Chemistry #1
Attraction: Elements of Chemistry (Hypothesis) (Volume 1) - Penny Reid

Hypothesis, Book 1.1

I Picked Up This Book Because: It was a Kindle freebie.

The Characters:

Martin Sandeke: Strong, possessive and a “jerk-face”
Kaitlyn “Katy” Parker: Logical, introvert, stupid smart.

The Story:

After Katy uncovers a plot to harm her lab partner, Martin he reveals his true feelings for her. Martin ends up whisking Katy and her best friend Sam away to a private island for a spring break getaway where they decide to take some time to get to know each other. Katy has already made up her mind that Martin and she will never happen but he does his best to try and change it.

This book reminded me what joy could be with reading. It was fun and free and covered a range of emotions. I felt an instant connection to Katy. We don’t learn much about Martin but I hear that changes in book two. He obviously has some things he needs to come to terms with and Katy is ready to take on that challenge. This really was a delight to read.
