Death is stalking the streets of Newcastle.

An anonymous killer is offering the terminally ill a dignified escape. Mercy to some. Murder to others.

DCI Jack Parker doesn’t want the case. He has a secret of his own – an early-onset dementia diagnosis he’s desperate to conceal. But the signs are becoming impossible to ignore.

As his mind begins to betray him, the city faces its own moral reckoning. While politicians debate a contentious new law and the self-styled Angel of Death selects another victim, Jack’s world is shaken when the killings are traced to a carers’ support group – one his wife, Helen, has been attending in secret. Yet his deepest fear is also his darkest temptation.

Because when his disease becomes unbearable, Jack can’t escape one haunting question: could the Angel of Death be the saviour he’s been waiting for?
