The Hidden Tunnel, the fourth book in The Mystery House Series, is now available in audiobook!
Ellen, Sue, and Tanya travel to Portland, Oregon where a local billionaire has promised to give them his current renovation project - a historical carriage house in the downtown area - if they can find his missing brother. As they dig deeper into a local legend, they soon fear that the cause of the brother's disappearance is more sinister and more powerful than ghosts.
Praise for The Hidden Tunnel:
"I disliked the fact that the book came to an end. This series is one of the best I have read in a long time. I can hardly wait for the next book to come out. "--Jon C. Scones
