Whoever Slew Auntie Roo?

An ex-music-hall singer becomes a recluse following the death of her only daughter. She keeps the child's room exactly the same as when the girl was alive, rocking and singing to the cradle that holds the child's mummified remains. When she throws an annual Yuletide party for children from the local orphanage, she kidnaps one of the girls who reminds her of her daughter, but the girl's brother comes to the rescue.
