The Bomb Shelter
Harry called the authorities as soon as he got back up. He and Tracy had found a bomb shelter likely from the mid-20th century judging from the furniture Harry had seen. The police flocked the Parker residents throughout the week.
They uncovered more rooms in the shelter, sharing that the Parker house had been built over a World War II military bomb shelter. Of course, the Parkers were allowed to keep the shelter. As a thank you to the state, they donated the furniture inside it to the local museum.
