Family!

"Who was my sister? What did you do to her?" She repeated her father's question but changed it as she didn't want him telling them that she was not alive once more. However she wanted to know who she was, what she looked like, what happened to her? She had the right to know it. 

"Would you like to guess? Let me give you a hint," He sat back on the chair and crossed his one leg over the other while his eyes were over her all the time. "You have heard her tragic story."

Isabella's mind was running miles per second upon his words but she can't remember any tragic story which she could consider of her sister's. Sure she had seen tragic ends or it would be more accurate to say that had sent many to their tragic ends in past two years but she couldn't relate any one of those to her sister which she never even knew existed until a while ago.
