I was back at the house, our old property, left empty and deserted for a decade or more. My name is Thea. This my inherited treasure which I was planning to sell to gather enough money to start my own hotel/restaurant. It had always been my dream to start my own business but I didn't have enough money.

In fact, I had once decided to convert the house itself into a restaurant but it wasn't in such a good condition. So its renovation would cost a hell lot of money. Oh how badly I wanted to keep it. This house had been in our family for generations. I wanted it to be my place. But I couldn't. If only I had a ginnie. But then I had another idea. I would sell the house.

So I came here today, to take a look at it. My lawyer had already found me a buyer. I wanted to see it myself and decide the cost. Well, obviously it was too precious to set a cost but we had to decide one.

I had lived in this house till the age of ten. It had my childhood memories contained in each and every corner. The person that I missed the most was my grandpa. He was a detective back then. I loved him so much. He gave me all sorts of puzzles and situations which I had to solve. So many games and so many tricks. When we left this house, he said one thing to me, "Child, this house will be yours one day as it was mine. You would probably want to sell it, but before you do so, I will have a puzzle ready for you. Promise me, you will...
