This is the fourth book in Ambrose Parry’s series of crime novels set in the medical world of 19th century Edinburgh – and it’s my favourite so far. Ambrose Parry is a pseudonym of Dr Marisa Haetzman, a consultant anaesthetist, and her husband, the crime author Chris Brookmyre, and they each bring their own set of skills and knowledge to the writing of these books. The series follows Dr Will Raven, assistant to the great Scottish obstetrician James Simpson (a real historical figure), and Sarah Fisher, who dreams of one day becoming a doctor herself, so each book includes a wealth of medical detail as well as a murder mystery to be solved.

In Voices of the Dead, set in 1854, Will is now married with a child and another on the way, but he doesn’t have much time to enjoy being a husband and father – not only is he struggling to move out from under the wing of Dr Simpson and establish his own reputation, he has also become mixed up in yet another murder case. Parts of a dismembered body have been turning up in random places around Edinburgh and Will’s friend, Dr Henry Littlejohn, has asked for his help in identifying the victim.

Meanwhile, Sarah Fisher’s plans to study medicine and follow in the footsteps of Dr Elizabeth Blackwell have had to be put on hold. Disappointed and frustrated, she turns instead to the emerging science of mesmerism, which is beginning to grow in popularity. An American mesmerist has just arrived in Edinburgh and Sarah is keen to learn more about the possible uses of mesmerism in healing patients. Will Raven, however, has a low opinion of such things and, not for the first time, he and Sarah find themselves in conflict. Eventually, however, Sarah is also drawn into the murder investigation and she and Will must work together again to find the culprit.

If you’re new to this series you may be wondering whether you could start here without having read the previous three books. Well, this one does work as a standalone mystery, but I would recommend reading all four in order if you can, starting with The Way of All Flesh. Will and Sarah have a complex relationship – made even more complex by the addition of Will’s wife, Eugenie – and it would be best to get to know them both from the beginning. There are also lots of recurring characters who develop throughout the series; in this book, I particularly enjoyed being reacquainted with Gregor the giant. Like the real life Irishman Charles Byrne (whom I read about recently in Hilary Mantel’s The Giant, O’Brien), Gregor’s size has made him the target of unscrupulous men who hope to acquire his body for exhibition after his death.

As well as the usual details of Will’s work as an obstetrician, I found it fascinating to read about the public displays of mesmerism, hypnotism and spiritualism being staged across Edinburgh and the differing views people held towards them. Were the mesmerists and spiritualists really just frauds preying on gullible victims, as Will believed, or were they acting with the best intentions, trying to provide comfort to people who needed it? This storyline introduces some colourful new characters, including a magician of whom I became quite fond and am hoping we’ll meet again.

Every book in this series has been very enjoyable, but I think this one is the best yet. I’m looking forward to the next one and hope we won’t have to wait too long for it!
