It starts with the opening sentences: the luxury apartment building is not a regular rental property, it is meant to lure only specific renters; the rental agent, Barney Northrup, is not a real agent at all, and the reader is told that he isn't even a real person. By the end of the first chapter, we're ready to become suspicious of everyone. Some of the characters don't even know everything about themselves; they're surprised to find that they've been named as heirs. A will is read, but it's actually instructions for a game. It seems that the will and the game it starts are meant to destroy one person and drive others apart, but it helps people break through barriers, find hope, and become closer; this theme continues until the final page.

The heirs appear to have lost the fortune, but they have gained new friends, refreshed relationships, and skills, contacts, and support that assure each one a bright future.
