When the ghostly rumors about a creepy abandoned house spark an undercover investigation, the kids have every intention of proving the rumors false.

Plus, the house would make a killer set for Noah's school film project, and he has to ace this one, so getting some good footage along the way would be a bonus.

But when they step into the shadows of Hemlock Hall, everything changes. Because this isn't just a spooky old mansion. It's a puzzle with missing pieces and a darkness waiting to be unleashed.

Grab this spine-tingling adventure where history, modern-day sleuthing, and the supernatural collide. Recommended for ages 9-12.

Warning from the author for readers 10 and under: No graphic violence or language, but this book is a bit scarier than the others in the series due to the nature of the haunted house setting.
