Alfred Hitchcock Presents Season 3 Episode 12

Miss Paisley's Cat

Miss Paisley adopts a stray cat. She names him Stanley. Stanley sneaks into the room of the violent tempered Mr. Rinditch. He tells Miss Paisley to keep the cat out of his room, but she fails. The cat sneaks into his apartment and Rinditch kills it. When Miss Paisley finds out, she grabs a knife to kill Rinditch, but she has second thoughts. She sits down and falls asleep. In the morning she wakes up wearing different clothes. The knife is also missing. She discovers that Rinditch has been stabbed to death and that a janitor has been charged with the crime. She is convinced she is the murderer but the police don't believe her. The janitor is later convicted and executed. Miss Paisley then discovers Stanley's collar. She remembers the murder. She did kill Rinditch and threw her bloodstained clothes and knife into a river. She now does the same thing with Stanley's collar so that no one can trace the crime to her.
