I read the author's How to Solve a Crime: Stories from the Cutting Edge of Forensics and rated it 10 star. It was a fantastic book combining Gallop's own story, investigations and details about forensic science that I had never read anywhere else. But reading this I am getting deja vu.

This book was published before How to Solve a Crime. It's an ok book, but I don't care to read the same stories again. What is new isn't as amazing as in the author's second book. It seems that the first, this one, didn't do particularly well, and then she wrote the second and thought no one would ever buy this, it had had it's day and failed, so rehashing the same stories was fine. From that angle it is. From the angle of one who bought both, not so much.

3.5 stars rounded up. But I wish I didn't have to.

I received a copy of this book in exchange for an honest review.

When the Dogs Don’t Bark follows forensic scientist Angela Gallop as she discusses her 40 year career within the profession. What follows is an outline of a number of her most memorable cases interspersed with the history and development of forensic sciences within the UK and it’s importance in the conviction, and defense, of individuals accused of a variety of crimes.

What immediately comes across while reading this is just how complicated and varied forensic science is. Far from standing in ditches collecting evidence from a crime scene, forensic scientists are wide reaching and branch into different specialties, from chemical, entomology, and one of the fastest growing - digital forensics. Often they must possess a thought process a little ‘outside the box’ too by taking the extra step of recreating scenarios in labs to determine the most probably outcome and unlock the truth about what happened at the crime scene. Two instances that stand out are when she mentions recreating the action of pushing a mop around a kitchen floor to exonerate a man accused of murder, and shooting a suspended pig carcass with a shotgun to discover where a specific shot went.

Other than a few glimmers of interesting cases and scenarios, this was a rather dry book to get through unfortunately. A lot of time is spent describing the different kinds of forensic scientists there are, and the various techniques which are used. It’s very science based, and talks in great detail about methodologies. There’s also a lot of detail regarding Gallop’s professional career and various businesses, however I found this could have been condensed, as it really took away from the more interesting cases. I think the book was approached very much like a scientific report, using cases to back up Gallop’s explanations of various techniques instead of letting the cases speak for themselves. It feels almost clinical at times, and there’s just no heart to the stories. A lot of the cases she mentions, she states she doesn’t know the outcome, and this got very frustrating at times as it came across as feeling unfinished and a little emotionless. Perhaps some more of her own personal background may have helped here, as we learnt a lot about her professional life but hardly anything personal.

I do find the synopsis a little misleading, as there’s no real depth to any of the memorable cases, sometimes they consisting of only a few paragraphs, and they are rather few and far between. The bulk of the book is centred around Gallop’s career and her explanations of what forensic scientists do. In this regard it’s meticulous in its presentation, but it wasn’t what I was expecting at all.

Interesting if you want to expand your knowledge of what forensic science is, but don’t go into it expecting lots of true crime stories or cases.

This is an intriguing read for both aspiring crime writers and those interested in the forensics associated with solving crime. I found it packed with great, fascinating information, and I was loathe to put it down once I began. As a law graduate, I know how much the criminal justice system now depends on hard evidence of the forensic sort, and Ms Gallop has dedicated her life to ensuring those who need to be incarcerated were. However, not only is this filled with truly interesting insight into the life of a forensic scientist it also is written in a highly engaging and readable way. The author indeed knows how to capture a readers attention.

It charts the developments and leaps forward made in this sphere over the years and applies the science to the evidence to show how conclusions are drawn. Gallop has been part of putting away some notorious criminals, and it's exciting to hear her perspective on the cases she has been involved in. I definitely feel this is written for the layperson and those who know nothing of the measures involved in such a job as it was written in an understandable, accessible fashion. This is the memoir of a real-life CSI analyst and it is nothing short of riveting.

Many thanks to Hodder & Stoughton for an ARC.

Whilst this book was mildly interesting, I think it was let down by the self-congratulatory ego massaging being paraded throughout.

I didn't get this book to read how amazing Angela Gallop's business sense is, I got it to read about forensic science, both in a historical and contemporary context.

I understand that the author entered into a field that was misogynistic and male chauvinist back in the day, and so achieved an incredible thing by rising to the top of her field, but I don't want to read about how this company was merged and acquisitions and sleepless nights due to financial backers!! Blah blah blah!!

I was most surprised by Gallop's willingness to review the evidence in the defense of the Bulger killers; suggesting that one of the heinous fuckers was slightly nicer and less involved than the other! Just no. As a case that was very close to home at the time, I was shocked that anyone would want to provide any sort of defensive evidence for these two evil bastards.

Rant over!!

The book was alright but I've read far better on this subject and would not recommend this to anyone wanting to know about true forensic science. Forensics: What Bugs, Burns, Prints, DNA and More Tell Us About Crime or Death's Acre: Inside the Legendary Forensic Lab the Body Farm Where the Dead Do Tell Tales would be better choices.

I love her writing style, from the first page I couldn't put the book down.

I liked to read about cold cases most. All the cases were interesting and important some more complicated than the others.

The thing I hated the most was her lack of empathy or compassion. I know she said in the beginning that she needs to distance herself from the crimes and the people she investigates but still the way she wrote about some aspects made me cringe. It was hard sometimes to read about some cases and realize that some people didn't get justice and she was like "meh well, what can you do?" Like yes, I know the justice system is fucked up and everything really is fucked up and we don't always get a happy ending but still, sometimes you need at least to reserve some hope.

Now, there was another con to this book but that was based on the fact that I didn't research before I bought and started this book. She talks a lot about the two companies she started and what she did there. Not really care about that aspect of her life because I came in this book for the forensic science parts it was boring at times to read.

In the big picture, this was a good book, got a little new information from it about forensic science and also about crimes per total. If you are looking for something more in-depth this won't be it though. Even though she is an important person in her field of work, she doesn't go way too deep into some aspects which makes this more a memoir/biography. This is still a good book and worth reading if you are interested in crimes and forensic science.

I paid top dollar to order this book when it first came out as it sounded so promising. Unfortunately, it struggled to keep my attention and, as I slugged through the pages, I was weighed down with the politics and the name dropping. It's hard to put into words what I didn't like about this book, but I think because it felt like a lecture rather than promising historical stories about forensic science, of its triumphs and it's limitations.

This cannot be compared to Unnatural Causes: The Life and Many Deaths of Britain's Top Forensic Pathologist at all, although it has been. Unnatural Causes was a phenomenal read; engaging, the right balance of procedure and story and probably the best book I have read on the field of forensics. This...this was dry as hell, an ego-massage for Gallop and just so confused.

Gallop mixes information about cases with her forensic businesses and her experience with them. Lay people who are reading about forensics don't want to know about your business acquisitions and start ups, the parties you hosted because everyone liked a good meal or you going off to train people for an MSc. Experts in the field would not appreciate the basic accounts of the cases, though may have some interest in the business side.

So really, this is a bizarre book which doesn't really know what it's aiming for.

An absolutely fascinating memoir, where the author describes many of the criminal cases she's been involved in, some of which are hugely recognisable and the science behind the forensic evidence that appears in court cases.

The author is extremely good at describing the way it all works in an accessible and very interesting way then showing how she applied the science to draw conclusions. I found the interpretation of evidence highly intriguing and after reading this I understand a lot more how you can have opposing forensic specialists.

Overall this is an excellent, educational read for anyone interested in the realities behind the fiction we all know such as CSI and crime fiction novels.

Very much recommended- although I feel I will read all that crime fiction with a much more focused eye.

This book is more of a memoir than in depth insight into cases that Gallop has worked on. Whilst the science is quite interesting behind forensics, this book spends too much time on the business workings, Gallops thoughts on forensic science and the internal politics of the forensic science world. The cases when they appear are fascinating from a different perspective however more time should have been spent on them. Give chapter 25 a miss - this is just a list of people Gallop wants to thank professionally and it's completely dull.

A fascinating and informative insight into the work of Forensic biologists and their colleagues.
Some very high profile cases are featured in this book, it is quite harrowing but extremely well written.
I’ve heard great things about this book from fellow science and criminology students, and it doesn’t disappoint.
A must read if you are interested in Science, forensics, crime, policing techniques, and biographies.

I picked this up on a whim because it looked like it could be my sister’s thing, and I never object to more random information about all kinds of topics. Angela Gallop is a well-known forensic scientist who has worked on several famous murder cases; this is a sort of professional memoir, barely touching on her personal life, but digging into her opinions on forensic science, her part in expanding forensic science services in the UK and eventually worldwide, and her involvement (sometimes tangentially) in various cases.

It’s a little bit of everything, really: she talks about setting up her business, and that butts up against the horrible details of bloody murders and the less than fascinating references to board meetings. It feels rather unfocused, sort of like there’s the kitchen sink at all: there’s certainly plenty of interesting anecdotes, but the wealth of examples sometimes bogs down her theme. Where you expect her to be contrasting two cases, they turn out to be remarkably similar and prove the same point. It’s not terribly written, but I’d tighten it up ruthlessly and make her add in an organising theme.

She does have something she wants to say about forensic science: “it’s more complicated than you think, it needs funding, it needs to be impartial, and it needs to be done in context”. But those cautionary notes for the understanding of and the future of forensic science get a bit lost when suddenly she’s complaining about the perils of borrowing money to start a company and how things could have gone wrong there. The book’s neither fish nor fowl; it’s not just about digging into the story behind investigating specific crimes, but it’s so heavy on those details that it feels like maybe that was the original point.

That said, the details are interesting and her style isn’t bad, just a bit flabby. I mildly enjoyed it, but felt it could’ve been more impactful if it knew what it was.

While there were a few moments in this book that made me audibly "wow" - particularly regarding discovery of important forensic clues and use of interesting techniques - I ultimately found reading this book dry and disjointed. The timeline of the author's career, accented by significant cases, felt mixed up and she frequently and unnecessarily repeats herself throughout the book. I felt that the blurb was misleading and, like other readers, expected more cases and less business/technical discussion outside of the casework.

The author did make some incredibly significant points related to the study and practice of forensic science, which I think anyone in a career related to the justice system should hear but, in my opinion, the book could have benefitted from some further editing.

This was a fascinating book for anyone interested in forensic science.

This book was really interesting. I enjoyed the short chapters, which made the book easy to read. The writing style was engaging and accessible, as scientific terms were explained fully.

Angela, highlights very well known cases she has worked on and some lesser known cases, so it was interesting to hear the details of these investigations.

Angela, also talks about how she got into forensic science as well some of the political and financial issues involved in forensic science companies and services used by the police.

Personally, I would have liked less detail on the running of these companies and the intricacies in to how they work, their finances etc. as that was less interesting.

Nonetheless, this book was really interesting and I learnt a lot about the real world of forensic science which is very different from what is portrayed on TV. Highly recommend!

Just like what one of the reviewers ‘Sara’ stated that Forensic world is very complicated yet intriguing at the same time. I felt the book was good but I found I could only read a chapter or two at a time as I could not engage with it fully.
I am pleased that Professor Angela Gallop progressed throughout her career showing that it’s not easy going out on your own and competing with other companies and as she rightfully said, when working for defence teams, you will always respect your fellow colleagues findings even though there maybe difficult situations that can undermine a case.
So a very interesting read but sorry not a 5 star from me but could easily be a 5 star to someone who fully understands the Professors World.

When The Dogs Don’t Bark is the compelling memoir from the UK’s most eminent forensic scientist and some of the most fascinating criminal investigations she has worked on. ‘Finding the right answers is what forensic science is all about. What often matters even more, however, is asking the right questions.’

My friends and family know that I have a deep shameless obsession for CSI Miami. Horatio Caine is my fictional favourite and if I could live my life again I would have tried a lot harder to stay focussed in science so I could solve crimes on fancy glass whiteboards using snazzy software.

Of course, I know that real life forensics is a gritty, tough, and painstaking job, searching for clues and understanding all possible scenarios to solve a crime. When I’m not watching CSI, I am watching true crime docos and exchanging recommendations with my brother (yes, my parents raised a couple of creepo’s). The drawcard is two-fold for us, the dissection and psychology of a disturbed mind and the tenacious, smart and out of the box thinking of hard working forensic scientists and investigators. These awe-inspiring people find the tiniest piece of proof, seemingly from left field and crack a case taking a dangerous person off the street (Paul Holes im looking at you).

When The Dogs Don’t Bark had me hooked as soon as I read the book cover. Professor Angela Gallop shares her story, not just the cases she worked on and the one she wished she could’ve got to but all that happens inbetween. Gallop shares what it was like starting out in forensics in the ’80s and 90’s when DNA and forensics were on the cusp of huge changes and breakthroughs.

The reader also gets to learn about the career changes and business decisions Gallop made throughout her career and her fight against sexism and an initial scepticism for forensic science. I’ve seen a few reviewers who found the book a little dry in places, but I think that’s a bit of Gallop’s self-described ‘disassociative’ personality traits coming through. Business mergers, blood workgroups and hires of scientists aren’t nearly as exciting as nailing a murderer in a high profile national case, but what you’re getting here is Angela Gallop’s career in its entirety and its enthralling.

I remember as a teenager reading and hearing about the tragic stabbing of Stephen Lawrence and the heinous murder of young mum Rachel Nickell. To read the words of someone who passionately worked on these cases to bring about justice, whilst trying to not pin emotion or influence on a case was so interesting to me.

A must-read for anyone interested in forensic science and true crime. I read it one solid sitting and it’s been a while since a book had such a grip. Angela Gallop is inspirational.

So many things are good about this book. Angela Gallop had an interesting career as a Forensic Scientist at a time where so many changes happened in her field. She also worked on many prominent cases, and it is the cases that made the book a compelling read as it felt like a crime novel explained.

I did stumble a bit though with some of the book. I am not a fan of too much jargon and lots of the technical details went over my head, and I wasn't really interested in the business side of the book. I guess I wanted more cases and I think that all the crime books I read and shows I watch make you think that the Forensic scientists will be out there solving the cases, whereas in reality I am sure that they are in the lab most of the time.

I read this book with the hope that it would be reminiscent of ‘Unnatural Causes’, but instead found it a rather dull read that took me half the month to finish.

Whilst the premise is certainly interesting, as were the descriptions of work on the (primarily high profile) cases - I felt there was little rhyme or reason to Gallop’s writing. The story was not told chronologically - at times it felt chapters had occurred to her on the spot. I expected a book at forensic science yet walked away having read one that may as well have been about setting up your own business - for the establishment of Forensic Access and its selling seemed to dominate the book.

Whilst I’m sure a significant event, it really was not what I had envisioned when I bought this book.

Really disappointing.

Looking forward to meeting this author at the Derby Book Festival on June 6th this was a highly
insightful observation and perception of the forensic science industry. A front hand witness to its development, technical advancement and politically/policy motivated changes. Addressing the far reaching aspects of the industry as well as the broader elements of the challenges faced in the science and criminal investigations themselves.

Автобиографический роман Анджелы Галлов - самого востребованного криминалиста Великобритании по нераскрытым делам - покорил мое сердце.

Я есть быть честной, я и представить не могла что на деле - это не как в кино. Ни в одном: ни в документальном, ни в художественном.

Анджела Галлов рассказываем нам свой путь, начиная с того, что в целом-то она хотела изучать огурцы и их воздействие на благоприятную среду человека. Но что-то пошло не так, и на авось придя на собеседование - она получила зеленый свет работы - криминалистом.

Анджела всегда говорила, что " - Мне хотелось заняться тем, что могло бы принести пол��зу большему количеству людей прямо сейчас" и часто задумалась о том, правильно ли она выбрала профессию? Сможет ли она до конца своих дней копаться в грязном белье, видеть свежие трупы и обжигаться проявляющими растворами?

Наверное многие, как и я считали, что все достаточно просто при нахождении док вещей, а копы просто напросто ленятся и пьют кофе с пончиками. Вот как-раз это насмешище - полная чушь, которую нам часто показывают в разных фильмах.

Когда Анджела впервые пришла в лабораторию, что она увидела развешенные вещи в кровавых пятнах. Сказать, что ее это шокировало - ничего не сказать.

Но днем за днем она привыкала к обстановке. Ведь, работа криминалиста - это не только проявление вещественных доказательств с вещей, но и при надобности - выступление в суде.

Если быть честной, то рассказывать о книге можно - бесконечно! Ведь, она охватывает огромный период времени, в который мы погружаемся вместе с воспоминанием Анджелы.

По-мимо очень сокровенных слов о кропотливой работы криминалиста, Анджела рассказывает о громких делах, в которых участвовала. И как раз первое ее дело - поставила ее на путь истинный.

"Интересные факты:"

* Раньше невозможно было собрать все-все частички с ткани каким-нибудь хорошим прибором, поэтому использовали липкую ленту, которую потом рассматриваю под микроскопом и сравнивали уже существующие материалы.

*В годы, когда Анджела начинала работать не существовало интернета, поэтому, им приходилось вручную перебирать нужные документы в огромных архивах, а также проверять любую зацепку и находить новые.

* Чаще всего полицейские могут ошибаться и неоднократно допрашивать настоящего убийцу, но так и не поймать его года.

*Чаще чего правда оказывается в нашей работе - фантастическим вымыслом

*Возраст крови невозможно определить научным путем

*Полиция часто развязывает веревки, которыми был скован труп, а зря, ведь в узле криминалисты могут найти вещественные доказательства, оставленные преступником

*Анджела всегда использует просроченную кровь для моделирование событий, которая предназначалась для переливаний

*Характеристики волос даже у одного человека могут значительно отличаться друг о друга



и другие интересные факты вы можете найти в этой прекрасной книге.

I found this curiously mixed. The opening fifty or so pages felt a little basic, slightly oversimplified - I completely understand why this part of the book might serve both as an introduction to Gallop's story, and an introduction to forensic science.. but having read plenty about the field I found parts of the opening chapters a touch 'skimmed through' and simplified.

The body of the book however was impressive. I've a lot of respect for the author, her expertise and her achievements. The middle two hundred or so pages formed case studies and provided a more satisfying in-depth discussion of the forensic science involved in trying to solve these crimes. Gallop was extensively involved in the modernisation of the field of forensics in the UK and provided insight here, especially with regards the work she and the bodies she set up had done in looking at cold cases and in providing counter-checks of the forensic investigations performed previously on behalf of the police/judiciary.

Regrettably the final fifty or so pages were a little disappointing, dealing less with crime investigation and more with her later career and her views on the future of forensics. I understand as a memoir she had every right to include this, but it interested me less.

Gallop became a forensic scientist in 1974, when men thought they were better and a woman's place was in the kitchen. She fought hard to be where she is and to have a successful career. She's worked on such high profile cases as the Yorkshire Ripper, the abominable murder of James Bulger and the racially motivated deaths of Stephen Lawrence and Damilola Taylor. This book recounts her career and the parts she played in proving or disproving guilt. Some of the scientific descriptions were a tad dry and it could have done with a little more focus on people but it was still an interesting book to read.

This book follows the career of Angela Gallop as it develops from liking sea slugs to being one of the foremost forensic scientists in the Uk and indeed beyond. Within her career she carved a niche for herself in working initially for the defence and later in cold cases.

Some of the cases she describes are very interesting and the flow of the book works quite well. There is, however a lot of detail that can be mind boggling to the non- forensic specialist and also appears repetitively in the book.

There were parts i thoroughly enjoyed and others which i really had to slog through

I've read several books about forensic science and generally find them very interesting. This one, although extremely detailed and referencing several cases that were headline news in the UK, was arguably a bit too long and I was relieved to reach the end.
It was a very detailed narrative, focussing mainly on the forensic examination of fibres and scene-of-crime studies and explaining why DNA testing was such a major leap in the forensic sector, as useful for proving guilt as innocence.
Perhaps that was part of my problem with this book - it was obviously written for the uninitiated but contained too much detail for its intended audience.
Because of its length, I have only given it three stars.

This took me far longer to read than it should have... A lot of the chapters were very interesting and engaging but many were not. There was a lot of gumpf that just was not necessary, it often felt like a long-winded job application or business case.
Also the amount of times Gallop seemed to forget details or hadn't bothered to look into outcomes but still wrote about them got quite annoying.

For me, Sue Black is far better at blending the science and personal stuff!

Bottom line if you are into forensics/crime read this book and maybe skip some chapters.

Well that was disappointing.
On the upside, if I ever want to start my own business - again, again and again - I consider myself fully equipped.

Not so much with the forensics, though. Which is a bit of a letdown, as that was all I was really interested in.
