Answer:
Yes she does
Step-by-step explanation:
After an incident where Meg hits Ralphie when he touches her breast, Ruth beats Susan for "being in connivance" with Meg. When Meg tries to tell a police officer about the abuse, Ruth locks her in their bomb shelter, allows her boys to strip her, then leaves her bound and gagged all night.
Ruth locks up Meg in the downstairs basement and doesn't let her come out.
