Miért beszél annyit Mrs. Piper?

About

"Good evening... I'd like to report a murder... Where do I live? In the basement... but I'm not there now... I'm on the top floor, in the boss's room... Ah, I don't know who the body is... You like to know, I'm the cleaning lady... How can I check if he's just taking a nap? Maybe, but he's got a dagger sticking out of his back the size of half my arm... So I lock all the doors... don't touch anything... keep my mouth shut and don't tell anyone until you arrive..." - Mrs. Piper, the cleaning lady, begins the eerily cheerful, twisty story with her broken sentences, but at the end we are left with no answer as to why Mrs. Pipper talks so much.
