It's hard to say no to a handsome billionaire.
 
From USA Today bestselling author Eva Pohler comes a thrilling series featuring a hilarious trio of middle-aged friends who travel the country flipping haunted houses and solving old mysteries, no matter the danger. In this fourth book, The Hidden Tunnel, 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.
