Patrick’s betrayal of his marriage drives the rest of the story’s plot, leading to both his wife’s betrayal and that of his colleagues. When he leaves his wife, Patrick betrays not only the love Mary has for him but also the unborn child she is carrying and their private domestic life together. At the sudden breakdown of her marriage and the world she built around Patrick, Mary commits her own betrayal by killing her husband. Covering up the murder primarily for the sake of her child, Mary calls the police, maintaining a façade of innocence and manipulating the policemen to inadvertently commit a betrayal of their own. As they investigate the murder, the policemen unknowingly betray both their former colleague and their profession by drinking whiskey on the job and by eating the evidence, ironically speculating in another example of Dahl’s black humor that the murder weapon is “right under our very noses.” Through this succession of betrayals, Dahl seems to be suggesting that betrayal begets betrayal, that disloyalty and deception will only lead to more treachery.

“Here you all are, and good friends of dear Patrick’s too, and helping to catch the man who killed him. You must be terribly hungry by now because it’s long past your supper time, and I know Patrick would never forgive me, God bless his soul, if I allowed you to remain in his house without offering you decent hospitality. Why don’t you eat up that lamb that’s in the oven? It’ll be cooked just right by now.”
The woman stayed where she was, listening to them through the open door, and she could hear them speaking among themselves, their voices thick and sloppy because their mouths were full of meat.
“That’s the hell of a big club the guy must’ve used to hit poor Patrick,” one of them was saying. “The doc says his skull was smashed all to pieces just like from a sledge-hammer.”
“Personally, I think it’s right here on the premises.
“Probably right under our very noses. What you think, Jack?”
And in the other room, Mary Maloney began to giggle.
