I remember this episode of a series of that type about this young deaf-mute girl who is adopted by a family who allows her biological grandfather visitation. It turns out the grandfather has certain powers including telepathy with which he can communicate with his deaf granddaughter and also skills involving voodoo which he uses to instruct her to make "dolls" of her adopted family and their maid using home baked cookies and toothpicks. With these cookie dolls he uses a doll house replica of the family's home, instructing her to "put them all to bed" so they cannot be awakened. and set the doll house on fire whereby the actual house bursts into flames as well. The girls's deceased biological mother saves the family at the last minute by communicating with her from beyond the grave to instruct her how to "wake them all up".
Does anyone remember this? The girl looked like she may have been played by a young Jodie Foster(but that could be wrong).
