A victim on display. A detective on the rails.

Shopping with her sister, DI Amy Winter is admiring a Valentine's Day window display of a perfect bride encrusted in diamonds and resplendent in lace--until she notices blood oozing from the mannequin's mouth.

This is no stunt. A post-mortem reveals the victim was left to die on her macabre throne for all to see. When a second victim is found, it emerges that both women were 'Sugar Babes' arranging dates with older men online--and Amy finds herself hunting an accomplished psychopath.

As she tracks down the killer, Amy's instincts go into overdrive when the charismatic head of the agency behind the display makes no attempt to hide his fascination with her serial-killer parents. What exactly does he want from Amy? With her own world in freefall as her biological mother, Lillian Grimes, appeals her conviction, Amy pushes the boundaries of police procedure when a third 'Sugar Babe' disappears...Is she as much at risk as the killer's victims?
