All the Rules to Break (слэш)

A notorious serial killer returns after a three-year hiatus, reminding Detective Arthur Moss of the infamous case he couldn't close. But when the FBI becomes involved, Arthur is forced to work side-by-side once again with Special Agent Daniel Eames, a man who knows Arthur better than Arthur himself will ever admit. Both men must confront their past and heal old wounds in order to bring a psychopath to justice.
