​Three dead girls, and not a single lead.

​

It’s London, 1943 and nearly Christmas.

​

Everyone is tired of the war which never seems to end.

Detective Chief Inspector Robert Delaney is war -weary, recently widowed and short-staffed.

A killer is targeting young women, and he has no leads.

​

His Chief Superintendent tells him to “be creative", so when a line of enquiry leads to a chance meeting with a colleague from his past, he asks for her services once again.

Maggie Carroll is facing yet another Christmas without her husband, who is fighting on the front lines.

​

When a young woman from her daughter’s work place is murdered, Maggie is worried for her family’s safety. When she’s presented with an opportunity to bring a killer to justice, Maggie takes it, even though she hasn’t worked undercover for nearly twenty years – and no-one in her family know anything about her past.

​

The Silent Night Killer introduces the unlikely partnership of Maggie Carroll and Robert Delaney, the ex-spy and British cop, working to keep the streets safe, in war time London.
