This is an indispensable guide for fans of true crime and crime fiction, whether in books, film or on TV, who want to look behind the crime, to understand the mechanics of an investigation, to walk in their favourite detectives' shoes and, most importantly, to solve the clues.

To do that, one needs to be fluent in the language of the world of crime. We need to know what that world-weary DI is talking about when she refers to another MISPER. We have to immediately grasp the significance of the presence of paraquat, and precisely why it is still a poison of choice.

If you want to know how many murders it takes for a killer to be defined as a serial killer, what Philip Marlowe means when he talks about being 'on a confidential lay' and why the 'fruit of a poisonous tree' is a legal term rather than something you should avoid on a country walk, this is the reference book you've been waiting for.

It covers police and procedural terms and jargon of many different countries; acronyms; murder methods; criminal definitions, including different types of killers; infamous killers and famous detectives; notorious cases often referred to in crime fiction and true crime; gangster slang, including that of the Eastern European mafia; definitions of illegal drugs; weapons; forensic terminology; types of poisons; words and phrases used in major crime genres, including detective fiction, legal thrillers, courtroom dramas, hardboiled crime, Scandi and Tartan Noir, cosy crime and psychological thrillers; criminology terms; and the language of the courts and the legal systems of British, American, French, Nordic and other countries.

FROM ACONITE TO THE ZODIAC KILLER is an essential, go-to resource for readers and even for writers of crime fiction. More than simply a glossary, this is a guide that provides a doorway into a supergenre, and one that is not just for readers, but also for the many fans of film and TV dramas, of podcasts, and crime blogs. It is also an indispensable resource for writers or would-be writers of crime fiction.
