Answer:
The physical appearance of the landlady impacts the story in the way that no one can imagine her as a killer because her physical appearance is nice in some way.
Explanation:
The short story of the landlady written by Roald Dahl, is a story about a young man called Billy. He travelled from London to Bath and there he meet a middle aged woman. Then, he starts talking to the landlady.
The author describes the landlady as an old woman with a warming smile. She also has blue eyes:
"She was about forty-five or fifty years old, and the moment she saw him she gave him a warm welcoming smile."
"She had a round pink face and very gentle blue eyes."
“She seemed terribly nice. She looked exactly like the mother of one's best school-friend welcoming her into the house to stay for the Christmas holidays”
"He noticed that she had small, white, quickly moving hands and red finger-nail."
The physical appearance of the landlady impacts the story in the way that no one can imagine her as a killer because her physical appearance is nice in some way.
