Part V

Heart-broken at the disappearance of Kate, Pete looks to keep her memory in honour by pretending that she has gone to Liverpool to stay with a fictional uncle. To maintain this lie against the gossip of the town, Pete multiplies his lies in beginning to fake a written correspondence between Kate and himself. As Philip watches his friend's pathetic pretence, he feels the weight of his deceit, which causes him to take to drink and to pull away from Kate who has been secretly installed in his house. This situation continues until Kate leaves Philip so that he is relieved of his wretched situation.

Meanwhile, the child falls sick, the news of which reaches Kate where she had fled, in London. She returns to see the child where she again meets Pete before throwing herself into the harbour, attempting to end her shameful life. However, she is saved and immediately brought before the Deemster, Philip, to be tried. Philip realises who she is as he commits her to the prison in Castletown, and then faints. Whilst still in a swoon he is taken to Pete's house, where Pete hears Philip's feverish and unconscious confessions. However, instead of wreaking vengeance on Philip and Kate, Pete "realises that he alone is the person in the way, and therefore wipes himself out in order that the woman he loves may be happy.  So Pete determines to leave the island again, divorcing Kate before he goes and leaving Philip with the child and his best wishes. Philip then overcomes his final temptation, to take up the position of Governor, and confesses everything publicly and so unburdes himself. The final scene sees him retrieving Kate from prison to start life afresh.
