'My name is Dr Adeline Glen. Due to a genetic condition, I can't feel pain.'
All Boston Detective D.D. Warren remembers is walking the crime scene. Next, a creaking floorboard, a voice in her ear... Now D.D. is seriously injured and unable to return to work.
'My sister is Shana Day, a notorious child murderer. She has killed more people in prison than as a free woman.'
Then a second victim is found with the same calling cards left at the scene: champagne and a single red rose. D.D. may have seen the killer, but she recalls nothing from the night that may have cost her everything.
