"'On Scene and Dealing'" is a call sign made by a police officer to Control when arriving at an incident. This is Part One of the early career of DCI Sarah Rudd from 1997, when she joins the Hertfordshire Constabulary, to May 2003 when she is a Detective Constable. Each complete chapter tells of the her adventures facing knife wielding yobs, drug-crazed hostage takers, the tricks used by bullying parents and her tensions with male colleagues. She sees through an alcoholic guardian and a lying war veteran. She meets the man of her dreams and has a son. But she finds herself in a wife-swapping party and, in the last story, succumbs to the libidinous advances of a senior officer. But Sarah Rudd is on her way to the top and nothing will prevent her from becoming one of the bravest woman police officers ever to patrol the streets of the Home Counties.
