The Tunnel At Rogues' Hollow

Ghost legends have been around for centuries.  Teams will go to haunted places trying to prove their existence.  Henry and Dana are one of those teams...sort of.  They spend weekends and vacations investigating ghost legends, but Dana doesn't believe in the existence of ghosts.  She goes along enjoying the travel, the adventure, the antiquity in these out-of-the-way places.  A funny lady, she also likes to pull Henry's chain and be spanked by her man. He is her guy and no one else.
The pair venture into sub-Appalachia to find an abandoned tunnel near the remains of an old, rundown mining town.  The story is full of tongue-in cheek silliness up until circumstances become dangerous.  Henry and Dana unravel a century-old mystery, resulting in their becoming targets.
