Edinburgh physician Dr Will Raven returns for the fourth in the series set in Edinburgh in the middle years of the nineteenth century. Ambrose Parry is the husband and wife writing team of Chris Brookmyre and Dr Marisa Haetzman. For new readers, a brief ‘heads-up’ about the personal dynamics between the main characters might be useful. Raven is assistant to – and disciple of – Professor James Young Simpson, pioneer anaesthetist and the only real life character in the book. Sarah Fisher was once Simpson’s housekeeper and, briefly, Raven’s lover, but he has since married, as did she, but her husband is now dead. She has a burning ambition to become a doctor.

When Raven is summoned to Surgeon’s Hall by his friend Henry Littlejohn he becomes caught up in a chain of events which range from the comically macabre through to the murderous. Wrapped in a blanket and deposited in the bottom of a cupboard, a human foot has been discovered. The head of the College, the aloof and irascible Dr Archibald Christie has been informed. Anxious to avoid any whiff of scandal, and aware that Raven has something of a reputation as an amateur investigator, Christie orders Raven to discover the origin of the foot without alerting the police. Things spiral beyond Raven’s control, however, when other body parts are located. Along with the irascible detective James McLevy, all concerned initially make a wrong assumption about the person whose limbs seem to be randomly scattered around the city. Will Raven’s past is punctuated with several episodes that might be described as unfitting for a respectable physician, and one such – by way of an all-too-human ghost from the past – sets him back on his heels.
We are soon drawn into a fascinating parallel plot involving the ‘science’ of mesmerism. Its creator, the German physician Franz Mesmer has been dead for over thirty years, but displays of what we now call hypnotism are still able to draw crowds. The flames of interest in mesmerism are being found by the activities of two people. One, Richard Kimble is more of a stage illusionist but the other, Doctor Harland Malham, seems to have better credentials, so much so that Sarah is extremely interested in what he is doing. Her interest is heightened because, when meeting her for the first time, he suggests that she has an aptitude for mesmerism and could possibly be taken on by him as a trainee. Raven of course is deeply sceptical, but is acutely aware of Sarah’s determination to succeed in the medical profession by one way or another. Is she being duped? And who is the mysterious local businessman, Mr Somerville, to whom Sarah has become attracted?
One of the key elements in this series – and this book is no exception – is the nature of the relationship between Raven and Sarah, now Raven is married. He already has one child, a small son, and another is on the way. He is devoted to his wife Eugenie, but there is always a frisson between him and Sarah and we wonder, as readers, where this will end.
It doesn’t take a critical genius to work out that Brookmyre is providing the plotting and textual nuances while Haetzman is providing the (sometimes grisly)medical details and sense of medical authenticity. This is certainly one literary partnership that works very well, and the world of 1850s Edinburgh is portrayed in vigorous detail, contrasting the often squalid lives of the poor with the very different world of the more advantaged. The bottom line is that this is a bloody good crime novel, full of twists and turns, convincing historical ambience and main characters we believe in. It is published by Canongate Books and is available now.

Meanwhile, Raven has met – and fallen in love with – Eugenie Todd, the beautiful and intelligent daughter of another Edinburgh doctor, and has also become involved in a murder mystery. Sir Ainsley Douglas, a powerful and influential man of means has been found dead, and the post mortem reveals traces of arsenic in his stomach. His wastrel son Gideon is arrested on suspicion of poisoning his father, with whom he has had a fairly unpleasant falling-out. Raven is an old acquaintance – but far from a friend – of Gideon. The two knew each other from university and Raven has a very low opinion of his former fellow student, and is very surprised when he is summoned to Gideon’s prison cell and asked if he will investigate Sir Ainsley’s death.
