I will tell the answer to all your questions. John was a spontaneous man and he wanted to know how his Home sweet home originally looked like. He went down to “city records” and opted for blue prints of his house. Those plans had different story. He found out after studying the plans that there is something hidden beneath his backyard. He was startled and confused. He couldn’t figure out before, even after living there for so long. He couldn’t hold his curiosity anymore and he planned to find out the “mystery of the backyard”.
