SOLVED. NYC brownstone fantastical house, death theater in a children's book [s]

[Abigail]

This book was about a young girl who lived in a brownstone in NYC. Her father was a plumber. They had a strange neighbor with a fantastical house- he kind of reminded me of Gatsby. And he has this theater of death where everyone acts out and practices the script for how they will eventually die...

[Deborah]

Well I want to read it. How long ago did you read it. What was the feel of it (YA, mystery, horror). Did the people acting actually die.
