Ray Garwood attacks Marshall, blaming him for the death of his daughter due to an overdose. Garwood denies leaving the note, and Captain Larkin and Myerson believe him. Then an apparent break in the investigation comes when Briarly tells the captain that a priest on board may be an imposter, because he did nothing when it appeared Gruenwaldt was near death. Donaldson checks the priest out and discovers he is indeed an imposter and a known thief, thereby placing him under suspicion. Myerson looks for the priest, but finds him dead in the dumbwaiter. At this point the threatening letter's contents are revealed to the passengers. Briarly again notices that Barons seems the most fazed by the priest's death, and wonders if the two men knew each other. Soon a second murder occurs; flight attendant Vera Franklin is found dead by the co-pilot, meaning the real murderer is still lurking.
