From Edgar Award Winner Dori Hillestad Butler comes a new chapter book
mystery series, The Treasure Troop! Join Marly, Sai, and Isla, three
code-cracking kids on the hunt for an old neighbor's hidden treasure.
In the second book of this code-busting series, Marly, Sai, and Isla are
back on the hunt. After finding Mr. Summerling's hidden treehouse,
they've discovered a new set of clues for them to follow, leading them
straight to the heart of their mysterious neighbor's life: his house.
The same house Marly has been living next to all of these years, which,
they discover, is filled with hidden rooms and staircases. With just a
few scraps of papers as clues, and Mr. Summerling's angry son on their
tails, can the Treasure Troop find the answers they're looking for?
