The Landlady-Predictions

I first started to suspect that things in the boarding house were not normal when Billy read the guestbook, and found out that the last entry was two years old. How could a boarding house in a place like that have only two people in three years? It's almost impossible. Also, the way the landlady talks is kind of creepy too. I predicted that something bad happened to the two other guests, the story makes us think that they are dead also. And, I believed that something bad was going to happen, but the story didn't write about it in the end.
