"Homicide - A Year on the Killing Streets", by David Simon
http://www.amazon.co.uk/exec/obidos/...880788-8264625
Excellent "true-crime" book, which was the inspiration for the brilliant "Homicide: Life on the Street" US TV cop show.
The book is based on reporter David Simon's experience of following the detectives in Baltimore PD's Homicide Unit for a year. Well worth reading
