The MYSERY

One day I found a horse in my room.   I went to town and found that no one was there.  I went to  the mall and no was there, but the stores were open later. Jace and his horse that he named  Bill went to check the food store.  No one was there too,  but the doors were open.   He went to check the sewer, and all of the town people and had big party.
