When a woman is found strangled on a torture rack in the basement of her fashionable Highgate home, DI Madeleine Fox's squad are called in to investigate the murder. On the face of it a bizarre but straightforward case. Or is it?
Sometimes the truth has a dark underbelly and Operation Dark Lady uncovers a host of twisted dreams. But Fox, the only woman on the squad, is haunted by dark visions of her own and the nightmares dog her tracks on Dark Lady. The investigation charts a descent into London's S & M underworld, the murky politics of Freemasonry and heavyweight Westminster identities. By the time the file is closed, five people are dead, untold more lives irretrievably ruined, and Fox has learned more about the insidious certainty of evil than she ever wanted to know.
