This was a pretty cool little horror film, eh?  It's called _Trilogy of
terror._  The third is called "Prey," and it is *that* one that has the 'devil
doll' [Maltin] that persues her.
The whole film runs only 78 minutes, and I remember watching it on a "Movie of
the week," that ran 90 minutes.
Maltin indicates that it is available on video.
Good luck,
