In 1929 New York City, twelve-year-old housemaid Martha O'Doyle suspects that a wealthy recluse may be trying to communicate with the outside world through the paintings on her gallery walls.

It's 1929, and twelve-year-old Martha has no choice but to work as a maid in the New York City mansion of the wealthy Sewell family. But, despite the Gatsby-like parties and trimmings of success, she suspects something might be deeply wrong in the household-specifically with Rose Sewell, the formerly vivacious lady of the house who now refuses to leave her room. The other servants say Rose is crazy, but scrappy, strong-willed Martha thinks theres more to the story-and that the paintings in the Sewells gallery contain a hidden message detailing the truth. But in a house filled with secrets, nothing is quite what it seems, and no one is who they say. Can Martha follow the clues, decipher the code, and solve the mystery of whats really going on with Rose Sewell?Inspired by true events described in a fascinating authors note, The Gallery is a 1920s caper told with humor and spunk that readers today will love.
