A trial for murder takes a dramatic turn in A CERTAIN JUSTICE, when the brilliant lawyer Venetia Aldridge agrees to defend a man accused of the brutal murder of his aunt. For Aldridge the case means no more than a chance to show off her remarkable skills, but little does she know that she has just signed her own death warrant: Four weeks later, she is found stabbed in her chambers, her head covered with a bloody wig. Called to the scene, Commander Adam Dagliesh begins an investigation unlike any he has done before, struggling to penetrate the complexities and secrets of the tight-knit London legal community. Then, without warning, a second murder happens… Once again, P.D. James turns the classic English detective story into a powerful narrative, superbly told and rich with suspense.
