John Scaggs has written a really good introduction to the genre of crime fiction. This short and accessible book covers the history of tales about crime before detective fiction; the golden age of Agatha Christie and others; mysteries; hard-boiled crime fiction; the police procedural; the crime thriller and historical crime fiction. As well as being a lucid and well-organised introduction, this book offers some fascinating insights: for instance Scaggs explores the relationship between hard-boiled fiction and the wild west stories that preceeded them. He also takes an interesting look at the role of crime fiction in supporting the status quo. This is thorough and excellently done and I would recommend it to anyone studying crime fiction in college, or who is a fan looking for some analysis of the books they love.
