Whispers in the Attic: The Past Won't Stay Buried (Julia Wright Mysteries)

Inventorying the attic at the library should not be that hard. At least until you find a hidden space where a body is buried. Can Lucy and Julia solve this case before they and others are eliminated?
Secrets long kept hidden about graft and other felonious deeds make this book have all kinds of twists, turns and threats to go with them. You will never figure out the ending so you will just have to read from cover to cover.
