Olivia and the missing toy

Olivia is one of my favorite characters. She is funny,smart and caring. In this book Olivia has lost her toy. Who could of took it? Could of her little brother Ian have taken it? Or her brother William? When Olivia was practicing her piano she heard an awful sound. The sound got louder and louder and of course she followed it. And thats when she saw it.It was......THE DOG. And he had chewed her toy to bits. Olivia is a good character.
