Landlady Alternate Ending

"No thank you," Billy said. The tea tasted faintly of bitter almonds, and he didn't much care for it.
"I very much appreciate the tea, but I am feeling quite tired from my journey. I think I'll have to retire to bed." Billy saw a faint glint of happiness in the landlady's eyes as he said this. Oddly, he didn't think much of it.
"Alright, dear. I do hope you sleep well. The tea should help. Do you need help finding your room again?"
"No thank you," Billy said with a smile," It is quite easy to find"
Billy got up from where he was sitting and made his way to his room. When he was about to open the door, Billy remembered something quite strange. The two previous visitors before him were still at the bed and breakfast, so why didn't they
He felt as if his heart stopped. Leaning against the wall for support, he beat his chest with his fist. When he had calmed down, he walked closer to the landlady. "Thank you very much! I will be sure to drink it!" The landlady smiled and left. Billy moved towards his bed in deep thought. How had she gotten in his room? He had left before her.

There were two men. Billy knew this was not normal. These men must have been good friends. He approached the door. It looked different than his door, heavier, noise proof. Billy opened the door to a broom closet. His face twisted in surprise. The other visitors were supposed to be on this floor. He stepped into the closet and turned on the light. He must be missing something. That is when Billy saw it. It was a small attempt to hide a door. Billy moved aside the shelf. Whatever was back there must be important enough to hide. Billy closed his eyes and opened the door. Lights switched on one by one. This hallway seemed to never end. It had hundreds of doors, luckily each one was labeled. Billy passed the first door Taxidermy Room. He walked to the second Holding Room. Somehow Billy knew that this was the room he needed to
