Crowned as ‘crime-writing royalty’ by fellow Scot Ian Rankin, Denise Mina joins us for her latest mystery which ponders the question: if you were responsible for a miscarriage of justice would you admit it? What would you do?

Blood spatter expert Doctor Claudia O’Sheil’s evidence put a killer behind bars – or so everyone thinks. Since the trial, Claudia has learned a horrific truth: her evidence and her testimony were wrong.

Now as she takes the stage to give a speech before London’s elite specialists, Claudia has to choose: keep lying and leave the wronged killer behind bars or stand up, tell the truth and rip her life apart.

Denise will be in conversation with Prof Keith McLay, Chair of Derby Book Festival and Deputy Vice-Chancellor of the University of Derby.
