As far as it goes, this is an erudite, well-written and readable book which gives the modern reader enormous insight into the way British justice functioned in the first half of the twentieth century: How it worked in favour of the rich and powerful and worked against the underprivileged: How anyone found guilty of murder was usually swiftly hanged with little chance of a reprieve. Although the book deals in detail with famous and gruesome murders, such as the Crippen case, it is all understated and not sensationalist.
Sir Bernard Spilsbury was fallible. He made mistakes which sent at least one or two innocent men to the gallows. And at the other end of the spectrum, he made mistakes which allowed at least one or two guilty men to escape punishment. This book is written by a judge who basically puts Sir Bernard on trial and finds him guilty of arrogance, obstinacy and prejudice. Sir Bernard almost never admitted he was wrong. He traded on his reputation and for many years no one dared, in any substantial way, to contradict his "evidence". In court, he seldom backed down, even when confronted by powerful arguments that went against any of his opinions. He was moralist who disliked homosexuals and abortionists, amongst others, and who would deliver his "evidence" in a cleverly worded way that was not favourable to such people. To be succinct, the author does not like Sir Bernard and makes no bones about saying so.
I have two main problems with this book. One is that it is too biased against Sir Bernard. The man was a compulsively hard worker who took his work very seriously and who often got things completely right. That side of Sir Bernard hardly gets a mention. The second is that the book lacks authority when it deals with forensic pathology. The author is not a forensic pathologist and tends to skate over the medical side of things. The best person to dissect Sir Bernard's technical ability properly would be a top forensic specialist (such as the late Keith Simpson).
In conclusion this is a good solid contribution to the available literature on Sir Bernard Spilsbury and it ought to be read by anyone who wants to find out more about the man who was a legend in his life time and who put forensic medicine on the map (despite making some disastrous mistakes). However it is not the definitive work on Spilsbury and for that reason I can only award it four out of five stars.
