The tale tell heart What are the themes of this tale?

The story is not, by any stretch of the imagination a fairy tale if this is what you are thinking of. it was a Gothic Horror short story by Edgar Allen Poe. It5 is true a sort of adaptation- with only the slightest connection- yes the heart angle, was made up as either originally a story or novel and later a radio drama- I heard it last night on WBAi and it was called ( The Doll) a Girl of 7 receives an animated doll for a birthday present, the doll as a simulated heart action controlled by winding up a string- something like very early automatic cameras using a pull-out spring clip- I accidentally broke one of these..when I was a kid.. oh well. anyhow the tot , who is in no way retarded or stupid, is very much entranced with the doll, and names her after her deceased mother, Henrietta or Henny for short, in typical kid-fashion she goes somewhat overboard on the new toy./ The toy has to be periodically rewound, and the heart action is loud. it is a very disturbing story without ( Bad Child) or supernatural elements but it does pack a whallop. the Girl has a heart attack- in the radio drama it is not clear whether she survives or not. the Doctor comments the item ws (an ill-chosen Toy) as the Kid"s deceased mom died of- you guessed it a Heart attack, do not rewind people! I had never heard this story before- it was on (suspense) on WBAI. it may or may not have been originally intended for kids.Story is called (The Doll) but the Heart action is thematic.
