Charlie's Angels Season 4 Episode 20 Harrigan's Angel

When Starrett Electronics is the victim of a second large heist, Paul Starrett's insurance company insists he have additional help for Joseph Harrigan, a bumbling, disheveled private investigator covering the case. The Angels investigation develops leads and they question photo engraver Belkin materials and shipper Felber, who both have police records linked to Starrett. Kris and Harrigan figured out the heist method but Starrett has already ordered them killed. The Angels confront and arrest Starrett for robbing his own business. They then rush to Harrigan's apartment in time to capture Felber and Belkin attempting to kill Harrigan.
