Book excerpt: This new, fully updated edition of The Crime Writer's Guide to Police Practice and Procedure is the essential detective in your pocket - something to reach for when your writing needs that short, sharp shock of modern-day investigating. Every writer has paused at some key point in the development of their story to wonder what happens in real life. How would the murder in my story be investigated by the police? How far can I go without leaving holes in the plot? Can I use low count DNA to identify the killer? How does a cop react to a bloated body or, even worse, just part of one? Written with answers to these questions in mind, this is the essential guide to police procedures and practice written specifically for writers. A handy reference book to dip into, or a textbook to guide you from the outset while you are still developing your plot, this second edition of The Crime Writer's Guide to Police Practice and Procedure will leave you confident that you have covered all angles of your thriller. It would be a crime not to read it!
