Themes In Roald Dahl's Lamb To The Slaughter

Roald Dahl the author for child-fiction famous book titled “Charlie and the Chocolate Factory”, is also known for his works for adult-fiction, either it is novels or short stories. The way Roald Dahl tells stories is unique, included how he builds tension to the story by making the characters gone through a transformation.
Roald Dahl’s “Lamb to the Slaughter “ starts with a very detailed description of the situation of the house Mary Maloney and husband live in, as she is waiting her husband to come home from work.

Mary Maloney, who was a victim at first, but as the story goes on, she became a villain. This also happens to the husband, Patrick Maloney, who was a villain of the story at first, but became a victim of Mary at the end. Even the lamb itself is going through a metamorphosis. Lamb, which often used to symbolize innocence, is used by Mary as a deadly weapon to kill her husband, which is an irony. The metamorphosis also can be found on “The Black Cat” by Edgar Allan Poe, who has the anonymous narrator gone through a metamorphosis from the protagonist, and later on becoming the antagonist as we can see from his description about how he felt as the story narrated from the first person point of
