While both were happily engrossed, there was a sudden, loud knock at the door.
"Huh?" Tom grunted after hearing the wrapping of knuckles at the door. Stirred as well, Matt looked over at Tom to see if he had any idea. They shared equally confused shrugs.
"Hello?" Matt called out.
There was no immediate response until another swift couple of knocks.
"Were you expecting anyone?" Tom asked in a whisper.
"No, you?" Matt returned.
Tom shook his head. Unsure what else to do, he rose and walked to the door slowly. There was no peephole but there was something casting a shadow under the door that he could already notice. Making sure to keep the chain still locked, Tom turned the deadbolt and poked his head out to see.
