A Haunted Hotel

I'm reading this book called A Haunted Hotel. It's about a boy, another boy,
and a girl. they're trying to figure out if there is a ghost in the hotel. They
saw the ghost by a elevator and they try and follow the ghost and in one of the
floors, they found that ghost and idk what happens next. last time i read that fudge book
and fudge wanted to know why the adults don't talk about money in front of everybody
and he wanted to know why....
