Inside a Police Informant's Mind
暫譯: 警察線人的心靈深處

Written by a former informant, Inside a Police Informant’s Mind presents an honest account of the role, risks, and motives of police informants. It chronicles the relationship and course of events between the author and a Royal Canadian Mounted Police commissioner. The author provides a fascinating insider's perspective on the working relationship between an informant and those in law enforcement who handle informants.

The book gives balanced insight into the thoughts of both the police and the informant, addressing the hazards of manipulation by both parties. It highlights the importance of trust, communication, and understanding as means to bridge those hazards. Also, it demonstrates the difficult shift in lifestyle being an informant entails. After testifying in court, Paul Derry’s life was placed at high risk of retribution, necessitating his entry into a witness protection program. He reflects upon the process of entering a witness protection program and life afterward, not only for himself but also for his family.

This autobiographical account is a must-read for police officers and informant handlers and is an especially useful source for intelligence gathering. The vivid, real-life accounts of Inside a Police Informant’s Mind are as revelatory as they are engrossing. It is a great addition to any collection of books on law enforcement and criminal justice.
