Dance with the Devil

In 1993, Paddy Doyle was responsible for the death of Lt. Cavanaugh's wife and child. Arson Detective Calvin Ghetts, who died recently, has been connected to Doyle, causing the court to consider letting him out on bond. Frost, Maura and Jane find photos in the exhaust pipe of a confiscated vehicle, which leads Maura to talk to Hope as the photos connect her to Doyle. She had helped bandage Doyle after he set Cavanaugh's apartment on fire. Hope must now testify in court. Maura, Korsak, and Jane go there and learn Cavanaugh is preparing to kill Doyle in the bathroom. Maura talks him out of it by saying Hope will testify against Doyle.
