Top flight criminal attorney Venetia Aldridge (Penny Downie), a high-profile woman with an abrasive reputation and turbulent private life, has been found dead in her office, stabbed through the heart with her own paper knife. Commander Dalgliesh and his team are called to investigate the murder. As Dalgliesh and Detective Inspector Kate Miskin (Sarah Winman) unravel the complex clues to Venetia's bizarre death, the other members of her prestigious chambers close ranks against the embarrassing questions of Scotland Yard's top commander. Then, just as a prime suspect is within Dalgliesh's grasp, an apparent suicide throws the case into turmoil. Roy Marsden stars as poetry-loving detective Adam Dalgliesh in this three-part adaptation of P.D. James' A Certain Justice.
