Why don't they laugh?

Welcome to Kensingtons’ Manor
A young lady named April arrives at an old manor in Maine to assist the Kensington circus dynasty's last heir in preparation for selling his family home. While carrying out tasks for this cheerful old man, she unwillingly learns more about his family's history and gets dragged into the family disputes of his relatives... who seemed to have died long ago.
Why has young Thomas left his parents’ house 50 years ago and never contacted his parents again? What events led to the most famous circus house in America being forgotten? And what sacrifices sometimes need to be made to become a famous performer?
Explore the manor and pay attention to all the details you find there.
After all, only you can determine how this story ends.
