White Victorian

at the very end of the film the doll is in a picnic basket in the back of the car
you see the dolls hands creep up and clasp onto the edge of the picnic basket,
the camera shot then goes onto the car, and it then crashes.
throughout the film the doll kills people with small knives etc.
It's an old black and white film,
must of been made in round about 1950's (i may be wrong)
it was around the baby jane era
and I have been searching for this film for ages.
and cannot find the name or the film anywhere!
if you could help me out in anyway at all id be extremly grateful
