Law of Perdition

A couple is found dead in a quiet Bucks County home leaving Detective Christopher Petrowski to follow some small but very ironic leads. Petrowski questions a young girl whom he finds oddly familiar though can't he place why or from where.

Detective Petrowski gets a lead on his current double-homicide case when a family member of the deceased is caught snooping around the crime scene. Petrowski also attempts to go on the mend with his daughter, Rebecca and realizes why the young girl on the stoop seemed so oddly familiar.

An unexpected high-priced attorney comes to the rescue of the Meth-dealing Will Pepper, forcing Petrowski's Captain to let him walk. Petrowski visits the site of a former cold case, bumping into the girl from the Walsh crime scene and does some off the record surveillance.

During a steak out Petrowski's new friend reveals her identity, causing him to have a near break-down. Malik's brother Aamir scolds him for tagging a bridge and Petrowski has something to show Angela that she might not be ready to see.

While Mr. Peck continues to fly under the radar as Bucks county's biggest Meth Dealer, Petrowski and Angela retrace the last moments leading up to her death. Rebecca invites her Father to Chloe's fifth birthday party and Angela reveals a strong lead in her case that points to Peck.

Mr. Peck is arrested under suspicion of multiple homicides only to come up clean. Petrowski shows up late for Chloe's fifth birthday causing more discord in his relationship with Rebecca and Malik's older brother Aamir clues Petrowski in on an important detail about the night Angela was killed.
