In “Lamb to the Slaughter” Dahl conveys dramatic irony through Mary’s dialogue when she speaks with the detectives. Dramatic irony is when the reader knows something that at least one of the characters doesn’t know. This can be shown when Mary offers the detectives dinner. “It’d be a favor to me if you’d eat it up” Mary knows the lamb is the murder weapon. Dahl’s readers also know the lamb is the murder weapon. Detective Noonan is clueless of this and doesn’t realize the lamb is the murder weapon. The detectives eat the lamb unaware of this. “Personally, I think it’s right here under our noses.”
