As Maisie is questioned and cleared by Detective Chief Superintendent Robert MacFarlane of Scotland Yard’s elite Special Branch, she is drawn into MacFarlane’s personal fiefdom as a special adviser on the case. Meanwhile, Maisie’s assistant Billy Beale is struggling with his own personal tragedy as his wife slips further into melancholia after the death of their young daughter.

The stakes are high as Maisie becomes involved in a race against time to find the man behind the threat before he can carry out his plans. Along the way, she must navigate a darkness not encountered since her days as a nurse in wards filled with shell-shocked men during the Great War.
