Complete story — includes the ending
Dexter continues to investigate Hannah McKay, suspecting that she may have murdered her late husband. Wanting to kill Hannah, Dexter sabotages the case against her, lying on the blood report and not testing for Hannah's blood at the crime scene. Sal Price ( Santiago Cabrera ), a true crime writer, approaches Miami Metro for case files on the last Wayne Randall murders, as he is writing a book about Hannah. Dexter later breaks into Sal's apartment to copy all of the digital files he has on Hannah. In them they reveal that Hannah poisoned the woman who bequeathed her a greenhouse business. Meanwhile, the Koshka Brotherhood blackmails Quinn by threatening to hurt Nadia so he will remove evidence linking Isaak to the murder scene at the Colombian bar. LaGuerta continues to probe into the Bay Harbor Butcher case. Debra finds out that Dexter was not completely truthful in the blood report on the Wayne Randall murders. Dexter takes Hannah out on a date where he intends to kill her, securing her to his kill table but ends up freeing her before the two have sex.
