'Under the dazzling glare of the electric lamp, Tartaglia saw the naked body of a young woman. She was kneeling down in the snow, head bent right over touching the ground, her face almost hidden beneath a tangle of pale blonde hair. He felt cold just to look at her.'

The young woman was Rachel Tenison, a wealthy art dealer, who led what appeared to be a normal, fulfilled life. But as DI Mark Tartaglia and DS Sam Donovan scratch away at the surface, a darker, secret side emerges.

Then a tip-off sends their investigation spinning in an entirely different direction.

Still haunted by the 'Bridegroom' case, which they were lucky to survive, Tartaglia and Donovan are forced to confront their own demons as they struggle to pin down the most elusive of killers.
