Crime's most original series character returns in a gripping new case.
Dr Harry Kent is on the edge...
He works too hard, sleeps too little, hardly sees daylight.
And then the Met police call him out to certify the suicide of a whistleblower from a world-renowned London children's hospital - a trainee children's surgeon who accused her boss of negligence.
Except someone held Susan Bayliss down...
The grieving parents of the children who died demand answers. The hospital is stonewalling. Everyone has secrets - it's up to Harry and DCI Frankie Noble to find out which were worth killing for.
But Harry's taking this personally... and that means trouble's on its way.
