Stranger in the House

Rudy had returned home, his mind buzzing with thoughts about the changes in the world he had observed. He went straight to his room and decided to connect to the neighbor's wifi to begin his research. However, before he could even start, something caught his attention.

His ears twitched as he heard the distinct sound of water hitting the floor. It came from downstairs, and Rudy couldn't fathom the source of the noise. His confusion deepened because he knew that Rebecca was at work, and no one should have been home.

Curiosity got the better of him, and he made his way downstairs. As he approached the bathroom, he realized that the sound was coming from there, and to his surprise, the bathroom lights were on. 

At first, Rudy thought he might have left the tap running and the lights on after his bath earlier, but he distinctly remembered turning everything off before leaving. He decided to investigate and reached for the bathroom door, only to find it locked.
