However, Gordon Draper, owner of Bondgate Books in Bishop Auckland, was recently looking through a pile of books in his shop when he discovered an envelope – which contained the letter and a photo of Lisa and Bethany.Mr Draper returned the letter to Ms Gash, after BBC Tees helped track her down.”I can’t emphasise how pleased I am,” he said. “Absolutely amazed.”The letter says: “If your dad is reading this to you it is because I have died and gone to heaven to live with the angels.”I will always be in the sky making sure you are alright and watching over you so when you see a bright star, like in the nursery rhyme Twinkle Twinkle Little Star, that’s me.
