Who was he talking to?
She kept her mouth shut while listening in the hopes that she would catch a glimpse of what her father was up to. It’s possible that she can piece together something meaningful from the sounds. However, he wasn’t making use of any equipment, and everything was happening at a lightning-fast pace. Abby was unable to hear a response even though it appeared as though he was having a conversation with another person. It’s possible that he’s on the phone.
A scary sound
Abby was the only one who could make out the odd sound, which was laughter. He was speaking so softly that it was impossible to understand what he was saying. If he seemed to be enjoying his actions, there is no reason for him to keep them a secret from his wife and children. During the time when Abby was getting ready to confront her father by knocking on the door, there was another sound that echoed through the walls.
