At the point of her retirement from the Metropolitan Police Service in 2019, Parm Sandhu was the most senior Asian woman in London's police force. She was also the only non-white female to have been promoted through the ranks from constable to chief superintendent in the Met's entire history. In this enthralling memoir, Parm chronicles her journey from life on the outskirts of Birmingham as the fourth child of immigrants from the Punjab to the upper echelons of the Met. Forced into an abusive arranged marriage aged just 16, Parm made the decision to escape to London with her newborn son and later joined the police as a constable. During her thirty-year career, Parm worked in everything from crime prevention to counter-terrorism, and she also served in the Met's police corruption unit. She played a senior organizing role in the London Olympics and was the superintendent on duty when Lee Rigby was beheaded in the street in Greenwich. However, Parm's time on the force was marked throughout with incidents of racial and gender discrimination, and, after deciding to make a stand, she found herself facing a spurious charge of gross misconduct. Black and Blue tells her shocking story and of her quest for justice in her police work and for herself. It is a story that cannot fail to inspire anyone who has experienced prejudice or abuse of any kind.
