Mary had just opened her mouth when her mother interrupted her and scolded her.
This time, Mary was not angry at being scolded. Instead, she focused on asking another question. She asked in shock, "Mom, how did you know about this?"
"The person who kidnapped your brother called me. He said that as long as you're obedient, he won't hurt your brother. You must not tell anyone about this. Otherwise, if something happens to your brother, I won't forgive you!" Her mother was probably frightened out of her wits; her voice was trembling.
"Mom, don't be so anxious. I know this matter is very serious, but we probably can't solve it ourselves, so shouldn't we call the police…" Although Mary was already panicking in her heart, she still tried her best to maintain her shock and comfort her mother.
