Dexter is none to pleased to discover a copy-cat killer has started his own attempt at vigilante serial murder in Miami. He is even less pleased to learn the new killer claims to be inspired by the Bay Harbor Butcher. As Dexter sets out to stop the imposter, he finds himself drawn into the arms of Lila. When Rita discovers the truth, it could be the end of their relationship.

After a fire at Lila s place, Dexter finds her becoming more attached to him than he is comfortable with.

Dexter stalks his latest victim: A man so vile he could only be a used car salesman. But Dexter finds the man s smooth talking charm and effortless lying something he lacks these days. In fact, Dexter s inability to lie to Rita about his midnight activities has caused her to think he is a drug addict and forced him into Narcotics Anonymous where everyone wants him to share confessions of his troubled past.

While pretending to be a drug addict, Dexter gets an N.A. sponsor to please Rita. But when the sponsor turns out to be a beautiful woman who may have more in common with Dexter, Rita is not happy. Things get worse for Rita when her estranged mother comes for a visit. Meanwhile, Dexter must find a way to lead the all-too-smart FBI Agent Lundy, now working with Miami Metro PD, off his trail.
