Jackie dealt with rapists, wife beaters, murderers, blackmailers and armed robbers but it was tackling the corruption in her own station that proved the most challenging.
Ostracised and harassed by fellow officers furious that she reported the illegality of some colleagues, Malton used alcohol to curb her anxiety.
A chance meeting with writer Lynda La Plante five years later changed the course of her life. Together they worked on shaping Jane Tennison, one of TV's most famous police characters, in the ground-breaking series Prime Suspect. Not long after, Malton recovered from alcoholism and now works as an AA volunteer in prison and as a TV consultant.
Jackie has spent her life working in crime. Now she's ready to share her story.
