Why would a woman with everything to live for be driven to murder?

After leaving her work summer party on Plumstead common, twenty-five-year-old Courtney Baker drives into a busy bus-stop outside Queen Elizabeth Hospital, killing seven bystanders, and herself.

The pressure for answers from the police is immediate. When it’s discovered Courtney is an ex-drug user with a heart condition, it’s easy to jump to the conclusion that she relapsed. She must have lost control: of herself, and the wheel.

But Detective Liz Field is not convinced. Courtney was in recovery, a regular volunteer at narcotics anonymous, and there’s no evidence in her home or the car wreckage to suggest she was taking drugs again.

Yet there seems to be no other reason why Courtney would do this. She leaves behind devastated boyfriend Louie – who had kept their office romance a secret, but was about to propose – and their colleague Lara, who is hit hard by Courtney’s death, as she lost her own husband to an overdose on prescription painkillers.

Racing for a solution, Field must ask the terrifying question: what if Courtney wasn’t the murderer – what if she was the victim? And if she was really killed for no good reason, what’s to stop the murderer from striking again?
