The Opposite of Murder

***WINNER OF THE 2023 CWA DAGGER IN THE LIBRARY***

What if the only way you could prevent a murder was by confessing to it?

Jemma Stelling has confessed to a murder.
She is the police's lead suspect.
She couldn't have committed the crime.
She has an unshakeable alibi: at the time of Marianne Cass's brutal murder, Jemma was at the police station, confessing to a murderous obsession with Marianne.
Is Jemma Stelling innocent? Or is she an ingenious, cold-blooded killer?
Can you be guilty of the opposite of murder?
