Gemma Osbourne always wanted to be a cop. She served her two years' probation with Greater Manchester Constabulary then transferred to the Met expecting bright lights but getting leafy Surrey. Feeling isolated and home sick, she discovered a flair for driving and a fondness for nicking disorderly motorists. After four years on a response team, she successfully applied to become a 'black rat' and joined Met 315 Traffic Patrol. There, she excelled, flying through motorcycle, advanced driving and vehicle inspection courses. Not only could she drive anything put in front of her, she could strip down a vehicle and put it back together again. She had also passed her Sergeant's Exams and was often 'acting' Sergeant.
