What will it take to tell the truth when your life depends on a lie?

A year ago, a father and his fiancee were brutally stabbed in their opulent townhouse, sparking the most high-profile murder investigation in recent history. Blood spatter expert Doctor Claudia O'Sheil's evidence put the killer behind bars - or so everyone believes. Since the trial, Claudia's learned a horrific truth: her evidence and her testimony were wrong. And someone she knows made sure of it.

Now, as she takes the stage to give a career-defining speech before London's elite, Claudia faces a devastating choice. Protect her children and her livelihood with her continued complicity or blow the whole conspiracy apart and reveal the truth: not only is the real murderer still out there, they're in the audience.

As Claudia steps toward the microphone, she revisits that fateful night. What really happened? And what speech will Claudia give?

From The New York Times bestselling and Costa-shortlisted author, Denise Mina, comes a taut, intelligent thriller about power, class, and the lengths we're willing to go for family.
