Lamb to the Slaughter by Roald Dahl
Quick answer: Lamb to the Slaughter by Roald Dahl: summary with the ending, Mary Maloney and the frozen leg of lamb, the detectives who eat the evidence, and the title's double meaning.
Mary Maloney, six months pregnant, sits in a warm, tidy room with two glasses ready and waits for her husband, a police detective, to come home so she can watch him drink his whisky. Roald Dahl published Lamb to the Slaughter in Harper's in September 1953 and collected it in Someone Like You the same year.
It is the standard black comedy for teaching dramatic irony: the reader knows where the weapon is while a room of policemen eat it.
The story in brief, ending included
Patrick Maloney comes home, drinks more than usual, refuses supper, and tells his wife something the story never repeats, only that he is leaving and will see she is looked after. Mary, dazed, goes to the freezer for something to cook, comes back with a frozen leg of lamb, and swings it into the back of his head. He falls dead. Thinking of the child, she decides to act. She puts the lamb in the oven, practises a normal voice and smile in the mirror, and walks to the grocer Sam for potatoes, peas and a slice of cheesecake, chatting about Patrick's supper.
She comes home, finds the body, and this time her grief is real enough to convince the police who arrive, colleagues of her husband led by Sergeant Jack Noonan. They search the house and grounds for the weapon, a heavy blunt object, and find nothing. Mary asks them, as a kindness to Patrick, to eat the lamb that has been roasting all this time. They do, standing in the kitchen with their mouths full, agreeing that the weapon is probably right under their noses. In the other room, Mary giggles.
The characters
A wife, a husband, and the men who eat the evidence.
Themes: the lamb who slaughters
The classroom readings are betrayal and revenge, the domestic wife capable of anything, and appearance against reality, since the police read Mary as the helpless widow she was an hour earlier. The title reverses on itself: the lamb is the victim, the weapon and the meal, and the woman it seems to describe becomes the butcher.
The sharper observation is how little Dahl moralises. Mary is not punished and not condemned; the story ends on her laugh, and the reader's complicity in enjoying it is the real subject.
The craft: dramatic irony served hot
The opening promises marital calm and spends a full page on it so the blow lands harder. The turn is the swing of the lamb, told in a sentence. From there the story is procedure, and the ending pays off the oven, lit early and forgotten by everyone but the reader.
The technique to steal is letting the reader hold the one fact the characters lack and then bringing the characters as close to it as possible. A story whose ending is on the table for the whole second half is what the Storytelling mark on Writory's rubric is built to reward.

What writers can take from this
- For exams, define dramatic irony using the final kitchen scene.
- Explain the three meanings of the lamb: victim, weapon, meal.
- Note the mirror scene: rehearsing normality is the story's turn from impulse to plan.
- Writers: give the reader the key fact early and bring the characters as close to it as you dare.
- End on the character's reaction, not the crime's discovery.
Try it yourself
Write a story in which an ordinary domestic object becomes a weapon in one impulsive moment, and the rest of the story is the character calmly disposing of it in plain view of the people looking for it. Let the reader know everything; let the investigators come within a sentence of knowing. End on a private reaction.
