There's the Landlady. She seems friendly at first but has a very sinister side. Another is the Great Automatic Grammatizator's creator. His greed and ambition make him a memorable and somewhat terrifying character. And then there's the man in 'Lamb to the Slaughter' who is the victim of his wife's rather unexpected act of violence.
The Landlady is quite memorable. She has this strange, overly - friendly demeanor that hides her truly creepy intentions. In 'The Great Automatic Grammatizator', Adolph Knipe is a character that stands out. His desire to use a machine to replace writers shows his immoral and power - hungry nature. Also, in 'Man from the South', the strange little man with his bet - making obsession is very memorable.
