Meldrum gains entry to Jenny's flat on the same night she visits the church for confession. The summary does not specify exactly how he enters, but he appears to use his position as a priest to gain access, possibly claiming pastoral duties. He attacks Jenny's friend Robert, mistaking him for Terry Wyatt, Jenny's boyfriend.

Meldrum mistakenly attacks Robert because he assumes the man in Jenny's flat is Terry Wyatt, her boyfriend who pressured her into the abortion. Robert is merely a friend visiting while Jenny is out, making him an innocent victim of Meldrum's misplaced rage. This mistake sets Robert on a path that eventually leads to his death in the hospital.

Meldrum secretly records Jenny's confession about her abortion and relationship with Terry. He uses this tape as blackmail material to control Jenny, threatening to expose her private confession if she goes to the authorities or reveals his actions.

Meldrum kills Terry after Terry confronts him at the presbytery. Terry had learned about Meldrum's actions and threats toward Jenny, so he tracks down the priest to threaten him.

Bernard Cutler, the priest who is Jenny's friend, discovers the bodies of Terry and Vanessa and confronts Meldrum. Meldrum tries to deflect blame and claims Brabazon acted out of love for him. He appeals to Bernard's loyalty to the church, asking him to help cover up the crimes 'for the good of the church.' Bernard reluctantly agrees, though the summary does not fully explain his reasoning, possibly fear, shock, or a misguided sense of protecting the church's reputation.
