Law & Order: Criminal Intent

The Faithful (1x4)

:

Goren and Eames investigate the death of church sexton Morris Abernathy but soon find their chief suspect, Kevin Donovan, dead in his apartment. After realising that someone performed last rites over Donovan's body, the police realise that a priest was involved in the murder, and are led to a priest who has been desperately trying to keep a twenty-year-old secret hidden. Goren risks the prosecution's case by protecting an innocent third party who could lose everything if their own secret comes out.
