Fourth-Grade Book Club: Walls Within Walls by Maureen Sherry

This 2010 novel for tweens focuses on the mystery that must be unraveled by the Smithfork kids, who find, to their distaste, they don’t like living in the Fifth Avenue apartment their parents buy after their father, a video game inventor, becomes wealthy. But then it turns out that the apartment, previously owned by a deceased multi-millionaire, is a puzzle that involves the children traveling all over New York City to solve it.
