The last thing Boston Detective D. D. Warren remembers is walking the crime scene after dark. She is later told she managed to discharge her weapon three times. All she knows is that she is seriously injured, unable to move her left arm, unable to return to work. Six weeks later, a second woman is discovered murdered in her own bed, her room containing the same calling cards from the first: a bottle of champagne and a single red rose. The only person who may have seen the killer: Detective D. D. Warren, who still cant lift her child, load her gun, or recall a single detail from the night that may have cost her everything.
