Why would Nathan kil-l his biological son?". Steve Austin shrugged. "Well that is because he was not his biological son. Gretta had cheated on him after they got married and made Nathan believe that he was not the father of the baby until the biological father of that baby had contacted him and told him everything. One month after Gretta's wedding with Nathan, she had cheated on him. Just one month! Nathan's heart was broken and my sister had mended back the heart. Few months to Gretta's death, she had found out that Nathan had known about the paternity of the child for a long time and also how he had killed her child. She blamed him for killing her child but she was scared of her family finding out that she had committed adultery. With the kind of principled man that Alexander Anderson was, he would never allow her to have that inheritance because of that act of adultery that she had committed. Gretta had struggled on what to do, that was why she was quiet and pained without telling anyone the reason and eating herself up in silence". "Who killed her?". Raymond asked as he searched his eyes. "I killed her of course". Steve Austin answered. Raymond rolled his eyes. "You have a witness in prison that was with you the day Gretta was murdered". Steve Austin fumed at him. "I ki--lled her!!!". Raymond smiled. "Your sister kill--ed her". Steve Austin burst into laughter. "What evidence do you have to back that up?". Raymond smiled to himself. "Arnold...". "I have told you everything you bastard! I escaped from the prison and ki--lled that ba---stard!!!". Raymond walked out. He walked along the road, holding Rosa's hand possessively. He thought deeply about Arnold's last words. "When Arnold had sang that song to me, he had kil---led two birds with one stone". Rosa looked up at him. "What do you mean?". "He had used that song to link everyone that was involved in Gretta's m)urder but he had also sang Twinkle twinkle Little Star in a different way that day to tell me something". "How do you mean?". "Instead of singing it like this, 'Up above the world so high, like a diamond in the sky', he had repeatedly sang it like this, 'Up above the wall so high, like a diamond in the sky. He had said Wall, not World. He had repeated it so many times and emphasized the WALL so that I would get the message". "Are you saying that the evidence is 'Up above the wall so high, like a diamond in the sky'...it is on a wall?". He squinted thoughtfully. "Since everyone must have ransacked Gretta's room and his room, Arnold wouldn't be stupid to have hidden it there". "Are you saying that he would hide it somewhere with a high wall?". He nodded. "Should we go back to the house of the Andersons?". He drove to the place. Mirabel glared at them as they walked into the house. "Mirabel, do you have a high wall in this house? Something like a high wall?". "The play house? Only the play house has high walls and a small door. Why do you ask?". "Where is the play house?". She directed them to a pink and blue cartoon like house with very high walls and a small door that you had to crawl in to get inside. There was a small book that was placed on the high wall. Raymond climbed on a ladder and took the book. It was 'Twinkle Twinkle Little Star' rhyme book. He opened the book. The missing two pages of Gretta's secret book and a memory card was in it. Tbc
